    Exploring PSU Design and Testing with Cooler Master

    Exploring PSU Design and Testing with Cooler Master

    Choosing a PSU for your rig was once a relatively simple choice – roughly work out the wattage you'd need for your components and likely future upgrades and then buy whichever best suited your style and budget. However, within the last decade and the last few years in particular, users are becoming more aware that simply providing power to components isn't enough. The 80 Plus certification program, launched in 2004, helped to raise awareness about efficiency, especially as different levels (e.g. Bronze, Silver and Gold) were added in 2008. However, efficiency is still only another small part of the story. A proper power supply also needs to be able to supply constant voltages under any load level with minimal ripple (also known as noise). Thankfully, the PSUs of most leading manufacturers now do, but cheap units with low quality components inside may fail and put your entire system at risk in the process. PSUs without the ability to operate within specific electrical guidelines can damage components and at their worst can even be fire hazards.

    Testing power supplies effectively and properly is not easy or cheap, but it is important for the reasons outlined above – it's why you'll find so many graphs and figures in our latest PSU roundups. During our time at Cooler Master's new HQ in Eindhoven, we were lucky enough to sit in with René Grau, technical marketing manager, for a PSU testing session. He took us through the testing process and the professional equipment needed for it, which costs upwards of 50,000 Euros. All PSU models produced by Cooler Master have to be checked for quality using the lab gear. Of course, Cooler Master can also use it to keep an eye on the competition, though the focus is on quality control and fault checking of its own products.

    FSP Announces 80 PLUS Titanium Power Supplies

    Having committed themselves to ‘green image’ in switch mode power supplies (SMPS) for two decades, FSP Group’s corporate social responsibility (CSR) activities reflect in their dedicated policies toward safety, quality and environment. By innovation in improving the performance of SMPS, they put the Group’s CSR into action in energy saving and carbon footprint reducing product design. Among 80 PLUS certified power supply list, FSP Group’s brands headed the list with more than 390 models. Now they proudly announce to be the first power supply manufactory to launch the latest 400W SMPS with the most efficient specification–80 PLUS Titanium PSU.
    Keeping the CSR in mind, FSP’s R&D teams work tirelessly in increasing product efficiency. Development of what was to become the MIA ICTM(Multiple-Intelligence Ability) began in 2008, when FSP Group started to research active clamp forward topology. MIA ICTM, FSP Group’s own design patent, later became the core technology in Aurum series, which were recognized as high cost-performance ratio products by their customers.
    On top of this, we are also working on reducing heat generation that caused by energy conversion lost. The directions were taken towards circuit layout design, components placement and Copper Bus Bar usage. Effectively placing heating components is vital to create negative air pressure; while extensively using Copper Bus Bar to conduct a substantial current of electricity is beneficial for energy-efficiency considerations. Together these three elements laid the foundations of a new era: Taking efficiency to the next level, FSP Group are thrilled to launch a brand new 400W PSU model with 80 PLUS Titanium logo.
    Making SMPS as small footprint as 400W with up to 94.18% of the energy conversion efficiency not only significantly reduces energy wastage, but also makes it applicable to computers and office equipment which means energy saving was not just a slogan but a way of life. FSP Group have built a strong reputation for supplying high quality, most reliable SMPS and will add a significant value proposition going forward.

    Rosewill Capstone 750W Power Supply Review

    Introduction

    Today, we look at another new product that is being sold by a company familiar to many HardOCP readers, Rosewill Inc., a subsidiary of Newegg since its inception in 2004. Newegg was founded in 2001 by it's then parent company ABS Computer Technologies who has been a part of the enthusiast computer market since its founding in 2001. The now defunct [H]Consumer covered a few of its fully built computer systems back in the day. Over the years, we have seen a few power supplies from the ABS/Newegg/Rosewill conglomerate branded by ABS. The Rosewill product portfolio, however, is much more complete than the few power supplies we have seen previously from ABS and it includes just about every peripheral you can think of. Today, we are looking at our first Rosewill branded power supply with the Capstone 750W (Capstone-750) produced by SuperFlower.

    SuperFlower Computer Inc. is a name that may not be familiar to most of our US readers, but as a company SuperFlower has been designing and producing power supplies, and chassis, since 1991. In 2006, it expanded with the establishment of a new subsidiary factory, Jing Hua Co., Ltd, now handling its increased power supply production. While SuperFlower has not been a high profile OEM in the US, some of its products can be found branded by TTGI, MadDog Media, Kingwin, EVGA, and occasionally SuperFlower itself. One of the distinguishing points spearheaded by SuperFlower units was the inclusion of some of the first 140mm fans. While not historically found as the OEM behind ultra high end brands, SuperFlower has typically made good budget oriented offerings and it has produced a number of outstanding designs in the last few years.




    Stop and Smell the Roses?

    Today's Rosewill Capstone 750W is the first power supply we have reviewed sold under the Rosewill brand. At 750 watts though, it is going to be facing competition from a lot of other brands that have much longer histories of making quality power supplies and much greater name recognition. As such, the Capstone 750W is going to have to truly shine if it is going to attract much attention of a good nature. Previous offerings from Newegg such as the ABS branded power supplies, however, have not exactly shined in our testing so that is somewhat of a concern today. Before we start too far down that track though, what does Rosewill have to say about this unit to allay some of those perceived fears:


    Features
    • 80 PLUS GOLD Certified
    • Continuous 750W@50°C
    • Supports Intel Haswell CPU C6/C7 Low Power State
    • Single strong 12V rail – idea for Gaming system
    • SLI & CrossFire Ready – 4 x 6+2pin Connector
    • 1x Silent 140mm Fan with Auto Fan Speed Control for better silence
    • Active-PFC with auto AC-input voltage adjustment(100-240V)
    • Black Coating Housing
    • Mesh sleeving on all cables for easier cable routing and better ventilation
    • Over Current/Voltage/Power Protection,
    • Under Voltage Protection, and Short Circuit Protection provide maximum safety to your critical system components
    • Safety & EMI Approval: cTUVus, FCC, CE, ROHS
    Well, the generic list of features that we find on many truly generic products did little in the way to inspire confidence in this unit today. That said, we have often seen where talk is cheap as well in the PSU arena. Let’s move on and see what we can expect when a user purchases the Rosewill Capstone 750W power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.

    Hardware.Info Taiwan Tour: FSP

    Introduction

    FSP is one of the lesser known power supply "brands" in retail, but it is one of the few that actually manufacture their own products – and not just their own products. We visited the company in Taiwan, and were offered a tour of their large R&D department and their extremely comprehensive testing facilities.
    FSP was founded in 1993 and is one of the largest manufacturers of power supplies, and not just for PCs and notebooks, but for LED lights, LCD displays, and industrial purposes as well. Their headquarters are located in Taiwan. No power supplies are actually manufactured here; instead, this location is used to design, test, and certify them. We were offered an opportunity to receive a tour of the headquarters, a truly special opportunity that we would like to share with you through this photo report.

    FSP's headquarters in Taoyuan, Taiwan.

    The entrance hall contains a scale model of the building...

    ... and a rather large reception desk.

    Before you're allowed anywhere else besides the ground floor, you'll have to replace your footwear with a pair of slippers.

    Cougar CMX 1000W Power Supply Review

    Overview

    We (well I) have been really impressed with the latest products from Cougar, with both the 700M and 700K walking away with a Gold award and Platinum award in recent reviews! So what will I make of the latest Cougar product to drop through the pcG door; the Cougar CMX 1000W Power Supply. This particular CMX version is the 1000 Watt version with 1200, 850, 700, 500 & 450 watt versions also available. All CMX PSUs feature a semi-modular cable system with the modular cables all being flat.


    The Cougar CMX 1000W came in a large smart black ‘n orange box with an oversized image of the PSU on the front, with the Cougar logo taking centre stage. The front of the box goes on to highlight Cougar’s Vortex fan technology and the fact that this PSU is 80+ Bronze rated (see here for more detail) and the fact that the PSU has a three year warranty.
    The back of the box highlights various features and technical information in numerous languages. In addition to this there’s a wealth of information on the main features of the CMX PSU range (see Specifications/Features below).



    On opening the box we can see that the Cougar CMX 1000W PSU isn’t very well packaged with the PSU itself just wrapped in bubble-wrap and left loose in an oversized box. Although, I did find all of the contents to be in good condition (luckily!)…



    In the box other than the Power Supply itself we find a bundle of modular (flat) cables, a very basic user guide and a pack of four screws.
    At the time of writing the Cougar CMX 1000W is retailing for approximately £150 on Amazon and comes with a 3 year warranty.

    FSP Aurum 92+ 650W 80 PLUS Platinum PSU Review

    We haven't seen an FSP power supply in the lab for quite a while. It was a stroke of good luck, then, when the company sent in a high-efficiency product with a reasonable output level in time for a comparison against two similar competitors. We already published the first evaluation in Corsair HX750i 80 PLUS Platinum Power Supply Review, and that solution proved compelling. As fans of FSP's 80 PLUS Gold-rated Aurum models, we're interested to see how the Platinum-class Aurum sizes up.

    Its enclosure differs in one small way from the Gold-class Aurum: the fan’s frame is not golden colored, but rather silver, hinting at the PSU's 80 PLUS Platinum rating. FSP's workmanship is otherwise perfect; the roughened finish gives the PSU an upscale look.

    Seasonic 1050 Snow Silent Platinum power supply review

    Seasonic SnowSilent 1050W 80 PLUS Platinum Certified PSU
    Today we peek at the Seasonic 1050 Snow Silent Edition Platinum power supply series. It's 1050W, Platinum certified, really silent, modular and can be spotted for just 235 EUR. Hell they even throw in a 7 year warranty. That just oozes value, features and lifespan for your enthusiast grade all black and white PC build. The trend lately is making the most energy efficient models. Platinum is what you want, however it's often expensive if you stick to the top brands like Enermax, Corsair, and so on.
    Today we're testing probably what is amongst the better power supplies we have had in our hands, and it comes from a bit of an underdog, Seasonic. You probably all have heard of them but they are not really that known. See Seasonic is primarily an ODM, (Original Device Manufacturer) which means the pure product ends up in a lot of PSUs from NZXT, Cooler Master, Corsair and so on.
    Seasonic just released a new model, all white with black cabling. it is a 1050W Platinum certified model that is very silent, modular and can be spotted for just 235 EUR. Seasonic will even throw in a 7 year carry-in warranty. That all makes a lot of sense as a secure investment.
    Next to we notice that the cables, sleeves and connectors have had an upgrade to receive an all black ribbon design. Forms, shapes and sizes, power supplies come in a wide variety these days. The trend lately is making the most energy efficient models though. Bronze, Silver, Gold but Platinum or Titanium is what you want really, however the upper stack in hardware remains expensive. T
    So today we peek at the Seasonic 1000W Platinum series. A PSU loaded with features and top notch efficiency, it certainly surprised us in a very good way. Have a peek at the product and then let's head onwards into the review.

    SilverStone SST-SX600-G 600W Power Supply Unit Review

    INTRODUCTION










    Everything seems to be getting smaller and smaller nowadays (oh miniaturization) from the very obvious everyday things like clothes and cars and up to electrical and electronic devices of all kinds. Of course PC hardware couldn't be far behind (although it actually seems to be leading the "pack") and so lately we've seen many manufacturers produce really small/compact CPU coolers, graphics cards, mainboards, PC cases, power supplies and even complete systems. Power supplies however have always been amongst the first thing people tend to check out when starting to build a brand new system from scratch and that goes double for mATX/mITX configurations. Well today we're going to take a look at what could be the solution for people after compact SFX form factor PSUs with adequate power outputs, the SST-SX600-G 600W by SilverStone.

    Founded in 2003, SilverStone is an established leader in its field, with an elite team of engineers; we started our quest of providing products that create inspirations. We have since expanded the lines of products as well as types of products we produce, giving our customers a wide selection of choices. With distribution centers in different areas of the globe, SilverStone products can be seen all over the world, not just for computer users but also for home entertainment use. Providing leisure with integration of advanced technologies that is functional and making them enjoyable to use. Here at SilverStone Technology, we continue to pride ourselves in providing the highest level of standards in designing and manufacturing computer enclosures, power supplies, and accessories. Our pursuit for the first class aesthetic appeal is relentless; our teams of devoted engineers are constantly searching for the best technologies that suit end-users with different needs and will make our products as technologically sound as they are beautiful.

    The SilverStone SST-SX600-G 600W SFX form factor power supply unit is the first of its kind to arrive here so the very first things that impressed us all after opening its box was not only its tiny size but also the very good build quality and its modular design (aside its very good specifications and features). Of course due to the very compact size of the SFX form factor we don't expect to see much higher wattage units anytime soon (if we see any and modular at that) but 600W should be more than just sufficient for mATX/mITX systems (some may even say overkill). As a matter of fact even the 80 Plus Gold certification was a surprise to us since the only PSU some of us were aware until now that could come even close to the SST-SX600-G in terms of size only featured an 80 Plus Bronze certification.

    Thermaltake Toughpower DPS G 750W


    Page 1 of 5
    When I was putting together the last few parts for our In Win D-Frame Mini build I knew I wanted to stick with a black and red theme and get a power supply that matched the performance of the rest of the build. Going with a Thermaltake Power Supply really was the only option to get both. So they were kind enough to send over their Toughpower DPS G 750 Watt power supply. While it fit everything I needed, it also peaked my curiosity. I mean, this is a power supply that comes with software. So today, beyond taking a look at the power supply itself, I will also be taking a closer look at the included software to see what it is all about and find out If it is something you really need or if it is marketing fluff.

    LanOC Reviews only covers the features of power supplies due to not having the equipment to test them up to our standards. Because of this you will not see a performance section, a final verdict, or awards. Therefore we prefer to call this a preview rather than a review.

    FSP Aurum PT 1000W PSU Review

    If you are building a new, powerful multi GPU gaming system then the FSP Aurum PT 1000W power supply will likely interest you. This high end modular unit is 80 Plus Platinum certified and the company say the design uses industrial grade Japanese capacitors with solid capacitors on the secondary side. It is a single +12V Rail design and features E-Sync Remote Sensing – providing synchronised 3.3V/5V/12V with superior noise and ripple suppression.

    The FSP AURUM PT 1000W utilises a 135mm fluid dynamic bearing (FDB) fan for long life, and to reduce noise levels as far as possible. The supply is coated in a ‘Granite touch’ finish which is said to be very resilient long term. The AURUM PT Series is available in three output capacities – 850W, 1000W and 1200W. FSP also include a 7 year warranty, for peace of mind. Product Highlights:

    • 80 Plus Platinum Certification.
    • Designed for gamers and overclockers.
    • Modular design.
    • Japanese capacitors.
    • Arrow shaped ventilation for superior cooling.
    • Quiet and long lasting 135mm fluid dynamic bearing (FDB) fan.
    • 7 year global warranty.

    MSRP:

    • 850W – €209,99 / US$ 219.99
    • 1000W – €229,99 / US$239.99
    • 1200W – €259,99 / US$279.99

    Antec Unveils 750W EDGE Silence Defined PSU

    Antec expanded its super-quiet EDGE Silence Defined line of power supplies, which made its debut in September with 550W and 650W model, with a series-topping 750W one, aimed with gaming PC builds with up to two high-end graphics cards. The unit is characterized by a 135 mm FDB fan that stays off until the unit kicks a load/temperature threshold; and rubber grommets and bands that dampen whatever little vibration slips out of the fan.

    The innards of the 750W EDGE Silence Defined are made by Seasonic, featuring a single +12V rail design, APFC, Haswell C7 state support, and all modern electrical protection mechanisms. The unit features fully modular cabling, with enough juice and straws to go around, for a build with two high-end graphics cards.

    Corsair HX750i Power Supply Review

    Introduction

    When Corsair first diversified into the PSU market back in 2006 with the release of the HX520W and HX620W, it is likely that not even they could predict that in 2015 their company would be one of the most active players in this segment of the market. After all, Corsair's primary focus at the time was memory-related products, with the company having seemingly zero experience on power supplies. At that point, it would be extremely difficult to project that nearly nine years later Corsair would be one of the most reputable PSU brand names and would be offering dozens of products through eight different PSU series.
    The people over at corsair did not limit themselves to releasing new models and series – they kept upgrading their old models as well. Today we are going to have a look at a unit from the latest revision of their HXi series, the HX750i. The HX series is of special significance to the company as it was their first PSU series. Much has changed since the first units that could barely get to 80% efficiency and had mediocre power output; the HXi series now ranges from 750 to 1000 Watts and are fully modular, digital units with an 80 Plus Platinum certification. That makes the HX750i the least powerful unit of the series and, with a retail price of $170, the least expensive one as well.
    Power specifications ( Rated @ 50 °C )
    AC INPUT 100 – 240 VAC, 50 – 60 Hz
    RAIL +3.3V +5V +12V +5Vsb -12V
    MAX OUTPUT 25A 25A 62.5A 3A 0.8A
    150W 750W 15W 9.6W
    TOTAL 750W
    Packaging and Bundle

    We received the Corsair HX750i in a relatively large cardboard box. The company opted for a straightforward, clean artwork theme for their enthusiast-grade PSU, which is mainly focused on a picture of the unit itself. The front of the box lists the most important features of the power supply, with additional details on its sides and back.
    Despite the class of the power supply, the bundle is rather spartan. Corsair only includes the necessary AC power cable, four black screws, a few small cable ties, and a case sticker. There are no cable straps, thumbscrews, or any extra accessories included with the HX750i.
    Every cable of the HX750i is detachable, including the 24-pin ATX cable. Corsair uses flat, ribbon-type cables with black wires everywhere, with the sole exception being the internal USB Corsair Link cable that is a typical USB cable with round black insulation.
