    Super Flower Leadex Gold 650w Power Supply Review

    Overview

    Despite having been established way back in 1991 we’ve seen very little from Super Flower in the UK until fairly recently and mainly in the form of Power Supplies. It’s worth taking note that they also develop and manufacture computer cases and a few other accessories as well, but it is really in the area of Power Supplies where they are most widely recognized (so much so, that companies such as EVGA use Super Flower as their OEM for some of their most highly rated Power Supplies). So rather handily I’ve been taking a look at the Super Flower Leadex Gold 650w.
    Super Flower manufacture a variety of the fully modular Leadex Power Supplies to suit your needs. We have the Platinum rated Leadex Platinum series available in 1200w, 1000w, 850w, 750w or 650w, then we have the Leadex Gold series available in 1300w, 1000w, 850w, 750w and 650w like our review sample. One thing they all have in common is the availability of white or black coloured powder coatings, then a little more interestingly white LED illuminated cable sockets!

    Leadex Gold series PSU are 80+ Gold certified with 100% fully modular cable design, our R&D team’s latest innovation, a brilliant idea to maximize PSU cables & connectors management to have the best cable routing solution, also increase case chassis air flow to have best cooling for your system. Leadex series PSU provides high efficiency & stable power output and come with a 14cm two-way thermal control intelligent cooling fan to ensure your professional PC system will work under heavy load, also capable of powering your PC system equipped with NVIDIA® SLI™ or ATI CrossFireX™ setup.


    The Super Flower Leadex Gold 650w arrived at pcG in a predominately black box, with golden yellow highlights and a honeycomb pattern in the background. Dead in the centre is a ‘super’ picture of a flower… Ok, it’s actually a giant butterfly which also happens to be the insect of choice for the company’s logo. Why? I’ve no idea (given you’d associate neither flowers or butterflies with power supplies no matter how ‘super’ they are, does it matter?), but due to their obscurity in regards to technology, they are sure to stick in your head. To the upper left we have the Super Flower logo, lower left is the PSU wattage, then to the right of this we have the model name and type, leaving the 80+ Gold certificate in the upper right.
    Over on the back and following a similar style we have the Leadex Gold 650w specifications (see Specifications/Features below), beneath this a brief description of the exclusive patents; the ECO Thermal Control System, then the High Power Vertical Double Layer Main Transformer. Whilst to the left of these we have several pictograms and labels for each of the Leadex Gold’s key features and a brief on what makes an 80 Plus Gold rated power supply.


    On the left side of the box, we have a list of the Leadex Gold’s key features (see below), below this is an image of the PSU which is partially transparent to show off its innards.
    Features

    • 100% Full Modular Cabling Design For Easy Cable Management
    • 80 PLUS ® Gold Certified, 90% 92% 89% Efficiency At 20% 50% 100% Rated Load
    • Full Range Auto Voltage Detection Design 100V~240V (Active PFC)
    • Comply With ATX 12V. V2.2, EPS 12V. V2.91 & SSI EPS 12V. V2.92 Specification
    • Comply With Energy Star Standard & EuP (Energy Using Products) Regulation
    • Over Voltage Protection / Over Current Protection / Over Power Protection / Short Circuit Protection / Under Voltage Protection
    • Support All Intel/AMD Multi-Core CPU & ATX/BTX Compatible Motherboards
    • Support NVIDIA® SLI™ & ATI CrossFireX™ High Performance Graphic Card
    • Patented Easy To Use & Install Crystal Clear Cube Connectors with LED
    • More than 2,000 times On/Off test
    • Unleaded Green Materials with RoHS/WEEE Compliance
    • Perfect For Professional & High Performance Gaming System

    Exclusive Patents
    (Taiwan & China Patents Approved, USA, Germany & Japan Patents Pending)

    • ECO Intelligent Thermal Control System
    • High Power Vertical Double Layer Main Transformer

    (China Patent NO.:ZL2009 2 0273193.2 ; Taiwan Patent NO.:M381155)
    Then on the right we have two angled images of the Leadex Gold, showing the available colours (white or black), our review sample is the black version.



    Upon lifting the lid of the box, we can see the Super Flower Leadex Gold 650w PSU is very well packaged within a very dense soft foam block, allowing no movement at all.

    SilverStone SX600-G 600W PSU Review

    SilverStone is no stranger to producing small-form-factor (SFF) PSUs capable of powering high-end rigs. The company has even provided guidance to Nvidia when designing for the nascent range of graphics cards that, at times, far exceed their rated TDP.

    Headlining the SFF range is the diminutive SX600-G that's presented in an SFX form factor. This means it is 100mm wide, 125mm deep and a maximum 63.5mm high - or just under 50 per cent of the cubic volume of a standard ATX supply. SilverStone adheres to the specification exactly, which is impressive given that a larger-than-normal, 80mm fan is shoehorned into the chassis.


    Click to enlarge

    Speaking of which, the all-black 600W unit is more functional than attractive. There's no power switch on the back, mind, with SilverStone using that space for the exhaust grille instead, and the only interruption to the design is for the specification badge on one side.


    Click to enlarge

    But looks are subservient to features and performance. SilverStone gets marks for making this high-capacity unit fully modular with respect to cabling, enabling tidy builds in the tightest of confines. The small size is visually reinforced by the amount of space taken up by the 24-pin motherboard connector. Four further ports, clearly marked, are used for additional CPU power connectivity, peripherals, and dual-plug PCI-E.


    Click to enlarge

    The package includes a special bracket for attaching the supply into chassis that only accept ATX supplies. Flat-ribbon cables make a lot of sense for SFF builds, too, and SilverStone varies length between 30cm and 70cm, depending upon cable-run. Here's how they stack up:

    Cables Length and plugs
    Main (24-pin) 30cm x1
    ATX/EPS (8-pin) 40cm x1
    PCI-E (6+2-pin) 40-55cm x2
    SATA 30-70cm x4
    Molex 30-50cm x2
    Floppy Extended from Molex (+20cm)


    There's enough cabling and power for all single-card builds commonly seen in SFF PCs, and the use of 16-gauge wire enables easily manipulation of the cabling... a must when space is limited. Users wanting smaller cables for tidier builds can purchase the optional 'shorter kit'.

    Amps/watts and voltage 3.3V 5V 12V -12V +5VSB
    Rail amps 20A 15A 50A 0.3A 2.5A
    Maximum rating 90W 600W 3.6W 12.5W
    Maximum continuous rating 600W @ 40°C


    It's common fare to have the maximum continuous power shunted down a single 12V line used to service graphics cards and the CPU. This 80 PLUS Gold supply's engineering credentials are further boosted by SilverStone specifying the wattage capacity at a 40°C ambient load, which is easily achievable, and likely, in an SFF build.

    The SX600-G's 80mm ball-bearing fan remains switched off at idle and low loads, according to the company, and only kicks in once the internal temperature exceeds 45°C - this usually happens at around 15 per cent total load. The fan then steadily ramps up from 750rpm to a maximum 2,300rpm when running at full chat.


    Click for high-resolution

    Inside, the Enhance-made unit has good filtering, excellent soldering and uses Nippon Chemi-Con capacitors for primary filtering and the cheaper Su'scon caps for some of the secondary-side filtering; we'd have preferred Nippon or Teapo to be present instead.

    High capacity, fully-modular cabling, and a good selection of cables do come at a cost when presented in an SFX format. The SX-600G's £100 asking price is steep, but, putting it in context, it's a niche product that has no real rival.

    SilverStone Announces SX500-LG Power Supply

    For small form factor enthusiasts, the standard SFX power supply form factor has excellent combination of size, power, and affordability. At 100mm deep, however, the standard SFX PSU is also limited in fan size to 80mm. While advances in engineering and components have made modern high-end SFX PSUs quieter than ever, there is still inherent limitation with 80mm fan’s ability to dissipate heat at maximum loading conditions while maintaining satisfactory noise profile for users sensitive to higher-pitch sounds. With this in mind, SilverStone has released a “lengthened” variation of the SFX form factor called, SFX-L. With 30mm of added depth, a SFX-L power supply has enough room to fit a 120mm fan, thus its maximum load noise can be not only lower in intensity (via slower fan speed), but also lower in pitch (due to larger fan size).
    The first model to debut in the SFX-L will be the SX500-LG, a 500W model that includes all features available from top of the line SFX SilverStone PSUs such as 80 PLUS Gold efficiency, modular flexible flat cables, and semi-fanless capability. An ATX adapter bracket is included as well to enable users to install this PSU into any small or even larger cases that do not have SFX mounting holes.





    Special Features:
    •Silent running 120mm fan with intelligent semi-fanless operation
    •Support SFX-L form factor and ATX via included bracket
    •High efficiency with 80 PLUS Gold certification
    •100% modular cables
    •All cables made with flexible flat arrays
    •500W continuous power output at 40℃ operating temperature rated for 24/7 operation
    •Class-leading single +12V rail with 40A
    •Strict ±3% voltage regulation and low ripple & noise
    •Support dual PCI-E 8/6pin connectors
    •Active PFC
    The recommended End User price (excl. VAT): $89.11 USD. The SX500-LG will be available in our stock on the 28th of January.

    Corsair CS850M 850W Power Supply Review

    Corsair has really made a name for themselves in the power supply market over the past few years. This is mainly because of their high-end AX and HX series, but at the end of the day not everyone needs a super high-end power supply. Corsair’s CS series is marketed more towards the typical user / builder who is looking for low energy use and easy installation. Today we are taking a look at the CS850M which is an 80PLUS Gold certified power supply. It also features flat modular cables and a 3-year warranty. Does this power supply hold the same high-quality and performance that we’ve seen from other Corsair power supplies? Let’s take a look! Special thanks to Corsair for providing us with the CS850M Power Supply to review.
    Features & Specifications

    Packaging
    The CS850M comes in the typical Corsair retail packaging. Corsair denotes their different power supply series by using colors, so the CS series uses neon green. On the front of the package it lets us know that the power supply is module, has an 80PLUS Gold certification and carries a 3-year warranty.

    The back of the retail box goes into great detail on the unit. One of the most important things is that it shows you the number of connectors that you do have. The ensures that you choose the right power supply for your system.

    Opening the box up inside you will find the CS850M power supply, a bag of modular cables, power cable, cable ties, mounting screws, users guide and warranty guide.

    Thermaltake Toughpower Grand 1050W 80 PLUS Platinum PSU Review

    Introduction



    Thermaltake is one of a handful of companies that have so many different lines of power supplies that their offerings are constantly evolving. This evolution allows for them to constantly inject new technologies into their line up and bring things to the table faster than others. This provides Thermaltake with a very distinct advantage over their competition as most companies tend to rely on annual or semi-annual refreshes of all their product lines.

    The Toughpower Grand series of units is certainly one of their most prominent series. Thermaltake injects their heart and soul into these power supplies to bring both beauty and performance to the table in a single unit. As such, it should come as no surprise that Thermaltake recently unveiled the next generation of Toughpower Grand units at this year's CES. The Toughpower Grand units have always fared very well for us and Thermaltake promises that this generation will not disappoint, so let's start digging into the 1050W model and see what we can find.


    Specifications, Availability and Pricing



    The Thermaltake Toughpower Grand 1050W Platinum power supply utilizes a single 12V rail design that is rated for 87A or 1044W. The minor rails share a combined maximum output of 120W, but are not rated for the same output individually. The 3.3V rail is rated for 25A and the 5V rail is rated for 22A. The 5VSB rail is rated for 2.5A or 12.5W. This seems a little bit low, especially for a 1000W+ power supply.


    Thermaltake never skimps when it comes to features and the new Toughpower Grand 1050W Platinum doesn't falter here. All protections are present including SCP, OVP, OCP, OPP, and OTP. All of the cables are modular and of the flat ribbon variety. The Toughpower Grand 1050W Platinum is rated for 80 PLUS Platinum efficiency and 100% continuous output at 50C.

    Thermaltake lists the Toughpower Grand 1050W Platinum with an MSRP of $209.99. This makes it one of the cheapest 80 PLUS Platinum rated units on the market. Adding to the sweet price that you can pick up this unit for, Thermaltake backs it with their seven-year warranty so you know that your investment is protected for years to come.


    PRICING: You can find the Thermaltake Toughpower Grand 1050W TPG-1050M for sale below. The prices listed are valid at the time of writing but can change at any time. Click the link to see the very latest pricing for the best deal.

    United States: The Thermaltake Toughpower Grand 1050W TPG-1050M retails for $185.86 at Amazon.

    Canada: The Thermaltake Toughpower Grand 1050W TPG-1050M retails for CDN$330.26 at Amazon Canada.

    CableMod PSU Cable Kit Review

    CableMod PSU Cable Kit Review

    Manufacturer: CableMod
    UK price (as reviewed):
    £69.99 (inc VAT)
    US price (as reviewed): $89.95 (ex Tax)

    We've reviewed a couple of pre-braided cable sets here at bit-tech. Shackmods' nylon stranded braided extension cables are pretty awesome-looking and available in multi-coloured options while many manufacturers such as Corsair offer their own pre-braided kits that actually replace the stock cables your PSU came with.

    The former might offer plenty of customisation but extension cables aren't ideal as you still need to use your stock cables for things to work. Corsair's own cable sets are perhaps a better option but the colours are fairly limited. We're pretty sure that you're reading this because you don't want to have to go through the hassle of doing it yourself and having done this ourselves a few times, we'd sooner opt for a pre-braided kit too.


    Click to enlarge

    Thankfully, if you're after more than just a plain colour and you don't want any sign of heatshrink at the end of the cables like many replacement kits use, then CableMod may have just the thing for you. Its kits replace your PSU's original modular cable set and at time of writing, it offers sets that are compatible with an impressive 56 PSU models from Corsair, EVGA, Seasonic and XFX - you can see the full list of compatible PSUs here.


    Click to enlarge

    We're looking at the C-Series red and black kit, with 'C' indicating it's compatible with Corsair PSUs, specifically those in the AXi, HXi and RM series. In the kit you get the full complement of cables:
    • 1 x 24-pin ATX Cable (600mm)
    • 2 x 4+4-pin EPS Cable (700mm)
    • 2 x Dual 6+2-pin PCI-e Cable (750mm)
    • 4 x 6+2-pin PCI-e Cable (600mm)
    • 1 x Quad SATA Power Cable (850mm)
    • 1 x Quad SATA Power Cable (700mm)
    • 2 x Dual SATA Power Cable (500mm)
    • 1 x Triple 4-Pin Molex Cable (750mm)
    • 2 x Dual 4-Pin Molex Cable (500mm)
    • 1 x Molex to Floppy Adapter (100mm)


    Click to enlarge

    The first thing that struck us, apart from the neat and slightly luscious packaging, was how flexible the cables are. Some kits we've seen have been very stiff, but these are based on a super-dense cloth braid that allows the underlying cables to be completely covered using less material. It's very noticeable when routing the cables through a case.

    Corsair CX750 750W Power Supply Review

    Introduction

    Corsair is known in enthusiast circles as a supplier of high performance memory and has risen to become one of the most talked about power supply brands around. Corsair was initially able to establish a presence in such a short time through the use of quality OEM’s (Seasonic and CWT), rigorous standards, and excellent support. Since its entrance into the PSU field, it has established a number of lines of power supplies of varying quality to address (and overlap) just about every market segment. Today, we have the first unit we have seen from Corsair's CX line; the CX750 (CP-9020015-NA). This unit is once more produced in conjunction with CWT.

    Channel Well Technology (CWT) was founded and began manufacturing power supplies in 1993. Since 1993 Channel Well Technology products have shown up under various guises including Antec, Xclio, 2theMax, CWT, Thermaltake, Xigmatek, and Corsair. While most familiar to our US users from when they used to provide OEM services for Antec, CWT is one of the more complete OEM manufacturers as they have a fairly high level of vertical integration providing transformers all the way up to its well designed independently regulated SMPS. However, CWT has been stretching out over the last few years and they are providing OEM services for a number of brands as today’s unit demonstrates.




    It's the Hobie Cat of the Fleet

    The Corsair CX750 is the largest member of the CX series of power supplies from Corsair. Over the years, we have seen a few lower end power supplies from Corsair and until recently those products have still been good options for users. However, over the last few years much if not all of the lead Corsair had established over other brands in every product segment we have seen has wasted away as their product lines have stagnated, reverted, or just been botched relaunches of products for no apparent reason. However, none of the products we have seen have been from an entry level product like the CX series (one of only three series we have not seen from Corsair), though the less than stellar CS550M is very close. So, how this unit will perform relative to the competition is certainly up for grabs today as history is not kind but this product is a bit of an unknown. Before moving on to see if this ship has started to right the course, let’s see what Corsair expects from this ship:


    CX Series PC power supplies are an excellent choice for basic system builds and desktop PC computer upgrades. CX Series PSUs are available in a variety of power configurations, and include features that are normally found only on premium power supplies.
    Moving on let’s see what we can expect when a user purchases the Corsair CX750 power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.

    Review: Fractal Design Edison M 750W

    Introduction

    Fractal Design is known to many enthusiasts as the designer of thoughtful, well-constructed chassis, with the Define series in particular winning general acclaim for ease of use and good looks.
    But like any company trading in the PC space, Fractal knows that diversification is key to ensuring business longevity, and this is why we've seen case fans, watercooling, and power supplies augment the traditional chassis base.
    The power-supply range is split into the Integra, Edison, Newton and Tesla series, with each offering something different, albeit often through overlapping wattages.
    A decent supply in 2015 needs to be at least 80 PLUS Gold rated in terms of efficiency, have modular cabling, and able to mete out capacity at high ambient temperatures. Fitting most of that bill is the newly-announced Edison M series, and we have the 750W version, priced at £85, in for review today.
    It's rare to find a poor-quality PSU these days, primarily because brands such as Fractal go to a handful of original equipment manufacturers (OEMs) who have years of experience in producing supplies for big players such as Dell and HP. An understanding of this fact is insightful when looking at the close proximity of results for various 80 PLUS Gold supplies; what we're really testing is the quality of FSP, Delta, Flextronics or CWT engineering, not the obvious brand's.
    But brands do choose how to implement the underlying technology and have a say in the design. The Edison M, available in 450W, 550W, 650W and 750W models, is unmistakably Fractal in appearance, and the overall aesthetic blends in perfectly well with, say, the Define R5 chassis. And while it's true that the PSU is generally kept out of the way, the recent trend of matching all hardware within a PC has positive implications for a company such as Fractal.
    Fractal designates this Edison M as modular but keeps a gaggle of wires fixed to the standard-sized supply. The 24-pin ATX, 8-pin CPU and two 6+2-pin PCIe are sleeved and hardwired to the unit. We understand the rationale behind the main power cables being fixed but feel that the PCIe should be fully modular, which is useful for people who may want to run the latest integrated graphics alone.
    Speaking of which, a further four PCIe 6+2-pin, 10 SATA and five Molex are provided in high-quality flat-ribbon runs, and the full cabling is arranged thus:
    Cables Length, plugs
    Main (24-pin) 55cm x1 (fixed)
    ATX/EPS (8-pin) 70cm x1 (fixed)
    PCIe (6+2-pin) 58-68cm x2 (fixed)
    55-65cm x2
    55-65cm x2
    SATA 40-76cm x4
    40-76cm x4
    65-77cm x2
    Molex 40-64cm x3
    30-42cm x2
    Floppy Extended from Molex
    Edison M's cables are longer than normal, especially the CPU 8-pin, so it's useful for bigger chassis, and the use of thin, flexible cabling certainly helps in routing the various wires through the usual motherboard cutouts.
    Looking back to the PSU's modular ports shows there's room for the full complement of PCIe, and up to four runs of either Molex or SATA. In other words, you can use all but one of the SATA/Molex cable-runs concurrently.
    Fractal forgoes the hybrid fan mode seen on some competing supplies by using an always-on Ong Hua temperature-controlled FDB-bearing 120mm fan identified as HA1225H12F-Z and coloured for Fractal's unique look. The control logic behind the fan ensures it spins at below 600rpm until 60 per cent load is reached (490W DC), and then ramps up linearly to 2,200rpm at full load.
    Peeking inside shows that Fractal uses the established, well-received Seasonic G-750 design for the innards of the Edison M. This means it uses high-quality primary-side capacitors from Rubycon while secondary-side filtering is taken care of by Nippon Chemi-Con - the large cap you see bottom-left in the above picture - and all the important caps are rated at a toasty 105°C. Just like the Seasonic unit, this one is backed by a five-year warranty.
    Soldering quality is excellent again. Fractal/Seasonic goes with the recent grain of pushing all the supply's available capacity down a single 12V rail. The minor rails still branch off the main 12V, showing this is another example of a DC-to-DC supply. We have no qualms about the quality of engineering supporting the Edison M.
    Amps/watts and voltage
    3.3V
    5V
    12V1
    -12V
    +5VSB
    Rail amps
    20A
    20A
    62A
    0.3A
    2.5A
    Maximum rating
    100W
    744W
    3.6W
    12.5W
    Maximum continuous rating
    750W @ 40°C ambient
    Higher ambient temperature ratings enable a supply to be used in smaller chassis or ones with limited airflow, and the Edison M's 40°C rating is consistent with most upper-mainstream models. Though thin on information, the provided user guide states that the 750W model can provide 80 per cent of its continuous rated output at an ambient 50°C.

    be quiet! Straight Power 10 700W CM Power Supply Review

    The phrase "straight forward" reminds me of going in a straight direction, one focus in mind, looking in front of you and not deviating your viewpoint at any time. When you really think about it, it is a very powerful statement. Straight forward makes you focus “straight forward” and not on anything else.
    The word "power" to me embodies strength, toughness, and an overall general ability to accomplish anything. It has been used in many mainstream media forms, for example; “by the power of Grayskull… I have the power”, “use the power of the force.” It carries an inherent strength, which just by the use of the word power means you are serious. When power is combined with other words, it strengthens the combined phrase. When we combine the two words we mentioned, straight, and power, it gives me the idea of focused strength, a power that is reliable.
    This topic brings us to the gold rated be quiet! Straight Power 10 700W CM power supply. Just from reading the title, we get an idea of a reliable power supply, with a great gold efficiency rating, which has 700 watts of continuous power, and is semi-modular. It is equipped with the new Silent Wings 3 technology which utilizes fins on the blades of the fan, as well as a funnel shaped intake port to direct the airflow into the power supply unit. The max sound produced at full load on the power supply is 23.1 dBA. Airflow inside your PC chassis can also be optimized with the be quiet! 700W CM (cable management), featuring all modular cables except for the 24-pin motherboard cable. Premium quality capacitors rated to 105°C provide maximum performance, reliability, and durability. With a full suite of safety protection circuitry built-in, as well as a 5 year manufacturer warranty, this power supply unit from be quiet! is sure to give you the longevity and reliability you are looking for. Along with cable lengths designed even for large computer cases, an 80 plus gold certification efficiency rating, SLI and Crossfire certification, support for C6 and C7 power states, and full Intel® Haswell support, the be quiet! Straight Power 10 series of power supplies, pack everything you need into a well-designed package.
