    EVGA SuperNova 1600 P2 80 PLUS Platinum Power Supply Review


    Can you have too much power? Well, in the case of PSUs the actual answer is “no”, but you can certainly spend more than you need to on a PSU with more power than you actually require. For most, a 1600 watt PSU would be a complete waste. Even higher end gaming systems rarely draw more than ~600 watts at peak, and if you are running some of the newer processors with incredible efficiency, that number could be lower. On the other hand, running multiple AMD 290/290x along with an overclocked FX-Series processor can draw some serious power. And mining can bump this even further. So, really, this article isn’t about figuring out how much you need. This article is for those who already know they need the power, and a 1600 watt PSU would fit the bill.
    So, yes, we are seeing great strides toward efficiency in most components, but we are also seeing more and more multi-GPU setups than ever before. When you put four cards in a system, even a card as hyper-efficient as a GTX 980, it is going to have some serious power requirements and an 850W PSU is not going to get the job done, no matter how good the quality. And multiple 290X with an FX-9590? Well, you are going to either need a nuclear reactor, multiple PSUs or the largest PSU you can get your hands on. It is these systems that the 1500W+ PSUs are aimed at, and it is these systems that actually need this kind of power. PSUs with this kind of output are few and far between, but now EVGA is answering the call and joining the ranks.
    With their largest power output unit to date, EVGA has also reached 80PLUS Platinum certification with their SuperNova 1600 P2. The SuperNova 1600 P2 is the current flagship in EVGA’s outstanding new lineup, and one glance shows many common traits with the balance of the line. The 1600 P2 uses the same outer shell styling we have seen in the SuperNova line, along with the same outstanding modular cable system. The 1600 P2’s cables are black from end-to-end, with individual sleeving at the ends. The cable assortment is abundant, and covers just about any possible setup, with nine 6+2 PCIe connectors plus four 6-pin PCIe for even the largest SLI/CrossFireX setups. Power delivery uses a single 12V rail capable of a whopping 133.3A/1599W continuous output at 50C. The 1600 P2 uses only top-quality components throughout, featuring all Japanese 105C rated capacitors. Full protection circuitry is used across both 12V and minor rails to keep your PSU and other components out of harm’s way. EVGA’s ECO fan system is used, allowing the unit to run passively at lower loads for absolutely silent operation. EVGA backs the SuperNova 1600 P2 with an industry leading 10-year warranty.

    XFX XTS Series 1000 W



    XFX's portfolio currently consists of three PSU lines. The most affordable is called TS and only includes non-modular units, the XTR belongs to the mid-level category and features fully modular low-to-mid capacity units, and the new XTS is their high-end line. The three members of the XTS family can, respectively, deliver 460 W, 520 W, or 1000 W, and the first two are also completely passive, which has them use no fan, while the third utilizes a hybrid fan mode where the fan doesn't spin up with light loads for a noiseless experience at those loads. All XTS units are manufactured by Seasonic, so we expect much in terms of performance.

    This review will take a good look at the XTS-1000, XFX's current flagship PSU. The unit not only features 80 Plus Platinum efficiency as it is also fully modular, uses capacitors of high quality, a key component in a good PSU, and promises very high performance under all conditions. Since we have come across this platform many times before, we are pretty sure its performance will be on par with that of the high-end competition. The XTS-1000 even features a unique external design, which will make it appeal to many case modders, and it, contrary to Seasonic's retail implementations which utilize smaller 120 mm fans with ball-bearings for significantly more noise under similar operating conditions, actually uses a 135 mm FDB fan. This unit will hopefully also use a relaxed fan-speed profile to fully capitalize on the additional airflow its larger fan provides

    Review: Antec EDGE 650W

    There is no shortage of quality power-supply units (PSUs) on the market. The sweetspot, as far as we're concerned, is with 80 PLUS Gold-rated models that offer fully-modular cabling. Significantly cheaper than Titanium supplies but offering almost all of the performance, these £70-£100 models are a good fit for anyone looking to power a new PC build.Stepping into this market is Antec with the release of a trio of new supplies that are marketed under the EDGE banner. Now available in mainstream 550W (£75), 650W (£90) and 750W (£100) capacities, the EDGE series combines high efficiency and modular cabling in one tidy package.
    The 650W model, in for review today, looks a little different due to the red bumpers on each side. These are easily removed and replaceable by a couple of black ones also included in the box. The supply can also be fitted without them, but it looks surprisingly good with the bumpers attached... assuming the insides of the chassis are also red. They are for more than looks, too, as Antec claims the bumpers reduce vibration in the chassis.

    Cooler Master V1200 Platinum Power Supply Review

    Even though 1200 Watts is ludicrously excessive for the typical modern PC, such PSUs are necessary for very advanced or application-specific systems, such as quad-SLI gaming computers and cryptocurrency mining rigs. The market for such equipment is small and very demanding, but succeeding at the top can also affect the reputation of the manufacturer, increasing the sales of their mainstream equipment. This desire to have the best halo product results in strong competition between manufacturers, and it also moves the industry forward as the new technologies developed at the top eventually make their way into mainstream offerings. We had a look at FSP's and Seasonic's offerings, the Aurum PT 1200W and the Seasonic's SS-1200XP3 respectively, a few weeks ago. Today we are reviewing Cooler Master's contender for the 1200W PSU market, the V1200 Platinum.
    The main difference between FSP/Seasonic and Cooler Master is that the former are ODMs (Original Design Manufacturers) -- they design, manufacture, and sell their own products. Cooler Master on the other hand has no such capability; their products are generally based on someone else's design (with tweaks and component choices made by Cooler Master), and this ODM also undertakes their manufacturing. This includes the V1200 Platinum, which the company hopes will compete in the top segments of the PSU market.
    As its name suggests, the V1200 Platinum is an 80 Plus Platinum certified power supply capable of 1200W of continuous output. However, any advanced user knows that these figures alone mean little regarding the actual quality and performance of a PSU. We are going to closely examine the efficiency, power quality, and thermal performance of the Cooler Master V1200 Platinum in this review and, more importantly, see where it stands in relation to the competition.
    Power specifications ( Rated @ 50 °C )
    AC INPUT 100 - 240 VAC, 50 - 60 Hz
    RAIL +3.3V +5V +12V +5Vsb -12V
    MAX OUTPUT 25A 25A 100A 3A 0.5A
    125W 1200W 15W 6W
    TOTAL 1200W
    Packaging and Bundle

    The packaging of the V1200 Platinum is simple and effective, with a serious, professional artwork theme. The front of the box notes only the most important features of the unit, but more information can be found on the sides and rear of the box. On the back of the box Cooler Master claims that this unit can save you over $450 compared to an 80 Plus Bronze equivalent -- if you have a 1000W system at maximum load powered on 24/7 for five years, that is.

    SilverStone Strider Gold 1500W Power Supply Review

    Introduction

    SilverStoneTek is a company best known for its high quality cases but its product lines extend into other components such as cooling, power, fans, storage, and so on. As a company, Silverstone has built up this impressive product repertoire in a very short time having been founded in 2003. Today, however, we are interested in its power supplies which are comprised of the Strider, SFX, Nightjar, Gemini, and Zeus model lines that range from 300W to 1500W DC output. For this review, we are looking at SilverStone’s largest capacity unit available at this time, the ST1500-GS, which is produced in conjunction with Enhance.

    Enhance Electronics Co. Ltd. was founded over 20 years ago in 1986. While a major power supply OEM Enhance is not nearly as well known to most users as some other OEMs as its core business focus has been outside of the desktop market in areas such as servers, embedded, and telecom markets. However, its products have started to surface in the US consumer realm in the last year or so under the likes of SilverStone, Silverpower, Antec, Cooler Master, and Thermaltake, as well as the occasional Enhance branded model.




    Can You Still Call it "Petite" if it is 1500W?

    Over the years, we have reviewed a number of power supplies from SilverStone including products as big as today's 1500 watt unit. One thing of note, that we have seen recently, is SilverStone's focus on physically smaller units with a few products that are even outside the scope of full size ATX/EPS power supply dimensions. Today though, we are looking at something of a hybrid product within this focus as the ST1500-GS is an ATX/EPS power supply but it is on the smaller end of that form factor. Previously, the 1500W units we have seen have been hulking behemoths that, while fitting the width and height of the ATX/EPS specification, were very long/deep products. Certainly then, a smaller product would be of interest to a number of people but, for us, just because it is a bit shorter does not mean we expect any less from the product. That all said, our previous experiences with SilverStone's truly high powered products have generally been good and we expect nothing less today. Before moving on, let's see what SilverStone has to say about this power supply:


    To meet the requirements of current and future desktop computers, SilverStone created the Strider Gold S series power supplies. The Strider Gold S models are all new designs engineered to be the smallest, full-modular ATX power supplies at any wattage levels.
    The Strider Gold S series includes wattage range from 550W to 1500W for a great variety of applications. With short depth designs, all models in the series are among the world’s smallest full-modular ATX PSUs. In addition to 80 PLUS Gold level efficiency, the Strider Gold S PSUs are built to meet very high standards in electrical performance with ±3% voltage regulation, ±3% ripple & noise, and high amperage single +12V rail. Other notable features included are 24/7 40℃ continuous output capability, low-noise fan, and multiple sets of PCI-E cables. For users looking for a power supply with faultless combination of compact size, performance, efficiency, and quality, the Strider Gold S Series is the only choice.

    Thermaltake Toughpower 1500W Gold

    “Holy smokes, look at the size of that thing!”
    “So. Much. Power!”
    Now I know what you guys are thinking. These are the kind of things we’ve all either heard (because of that monstrous 2 mile per gallon Escalade or Ram truck you drive; what were you thinking, hmm?) or long to hear. And, gals who love their guys – there are ladies who read and love Techgage, right? Right? – understand just what kind of thrill it is for their guys to hear these kinds of things.
    Well, I’ve got to confess that these were the same kind of thoughts that sizzled through my brain the first time I laid my eyes on Thermaltake’s Toughpower 1500W Gold power supply unit. As the name suggests, it’s a monster PSU capable of a max output capacity of 1500W. Thermaltake, though, says in its spec sheets that it is actually capable of delivering a peak output capacity of 1550W!
    There is no doubt that this is a true top-of-the-line model. If its power output specs aren’t enough to convince you, then its typical price of circa $300.00 should be. This is obviously a serious power supply meant for nothing but the most endowed PCs you can build.
    Let’s have a look at it, shall we?
    It’s a big boy, for sure. With dimensions of 86mm x 150mm x 220mm (H x W x L), it’s longer than most PSUs. This angle shows that the Toughpower 1500W Gold is a semi-modular unit. Quite logically, the 24-pin motherboard power cable and the 8-pin and 4+4 pin EPS CPU power cables are permanently attached to the unit.

    EVGA SuperNova P2 1200 PSU Review

    EVGA have earned a fantastic reputation over the years for their selected range of motherboards and graphics cards. Today we look at one of their high end power supplies – the SuperNova 1200 P2. This is a creation with OEM partner, Super Flower. The EVGA SuperNova 1200 P2 supply is full modular, 80 Plus Platinum certified and can be driven in a semi passive mode. The warranty is certainly exhibiting a confidence in the product that EVGA wish to pass onto the customer – ten years is not to be sniffed at.

    EVGA are keen to point out that the SuperNova P2 1200 is built with long term reliability in mind. They have opted for premium grade Japanese capacitors and selected high grade components throughout the build. We have reviewed a handful of Super Flower designs in the past and they have certainly left us with positive impressions so far. This unit is also Haswell compatible, using DC-DC converters for the generation of the minor rails.
    EVGA SuperNova P2 1200 overview:

    • Unbeatable 10 Year Warranty and unparalleled EVGA Customer Support
    • Highest quality Japanese brand capacitors ensure long-term reliability
    • Fully modular, to reduce clutter and improve airflow
    • Double ball bearing fan for exceptional reliability and quiet operation
    • Heavy duty protections
    • NVIDIA SLI and AMD Crossfire Ready
    • 80 PLUS Platinum certified, with 92% (115VAC) / 94% (220VAC~240VAC) efficiency or higher under typical loads.
    • ECO Intelligent Thermal Control Fan System (Zero Fan Noise < 45C)

    Chieftec Navitas 650W GPM-650C Review

    With the Navitas 650W Chieftec has a high quality mid range power supply in its portfolio which offers 650 Watt output power. When looking for an 80Plus certificate we find a Gold sticker on this unit. Since Chieftec doesn't own their own PSU factory, their using an OEM platform from CWT (Channel Well Technology) for this model. As usual we're curious to find out what this 92.90 Euro PSU is capable of.

    Chieftec A80 CTG-500-80P Review

    With the A80 500W Chieftec has an entry level power supply in its portfolio which offers 500 Watt output power. This unit is only compatible to 230V outlets and therefore Chieftec is mainly targeting the European market with this power supply. Since Chieftec doesn't own their own PSU factory, their using an OEM platform from High Power for this model. As usual we're curious to find out what this cheap 47 Euro PSU is capable of.

    Seasonic X Series XM2 1050 W



    This year was definitely a very busy one for Seasonic since they revamped all of their high-end lines with new models. They essentially modified their already very good high-end platform in order to ensure even even better performance. It is admittedly very hard to improve on such good design, but their engineers apparently all work around the clock to somehow find ways to do so. We have said so in previous reviews, but are going to mention it again: Seasonic's platforms push the analog circuit to its limit for performance that is almost on par with that of digitally controlled PSUs. However, we would like to see them introduce a digital platform soon since delaying the introduction of digital units any further would give the competition a huge head-start, and truth be told, the fewer player there are for digital PSUs, the less likely it is for their prices to drop to more affordable levels.

    We reviewed the SS-1250XM2 unit a while ago, and it left an excellent impression on us with its top-notch performance. Today, we will take a good look at the smaller model with 1050 W maximum power output, which is more than enough for a pretty demanding system. Like all high-end Seasonic units, the SS-1050XM2 is fully modular and comes equipped with a 120 mm fan of high-quality. We would prefer a larger fan for a quieter operation, but Seasonic has thus far insisted on using smaller fans than the competition. This unit is also 80 Plus Gold certified and offers a hybrid operation during which the fan doesn't spin at light loads. The hybrid fan option can be deactivated, which would cause the fan to spin throughout the PSU's entire load range, with its speed depending on the temperature inside

    EVGA SuperNOVA 1300 G2 1300W Power Supply Review

    Introduction

    As a company, EVGA was founded in 1999, and is well known in the DIY computer industry for its high performance video cards, motherboards, and other computer components. Recently, EVGA has expanded its product offerings to include power supplies which of course draws our interest to it today. Currently, EVGA has a few lines of power supplies with the majority being some variation on the SuperNOVA name and variously branded "SuperNOVA" or "SUPERNOVA". Today’s EVGA SuperNOVA 1300 G2 Power Supply, which is also listed in the EVGA literature as the SuperNOVA 1300W Gold, (120-G2-1300-XR) is one of the largest capacity power supply that EVGA offers in this product line and it is 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, 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, it has produced a number of outstanding designs in the last few years.
    Finally a Shining Star?

    There is an old urban legend that runs around which says the Chevy Nova did not sell well in Spanish speaking countries because the name means "no go" and people probably did not want a car that said, "no go." It is an urban legend, but the phrase "no va" can be translated as "doesn't go" somewhat correctly and, to date, EVGA's products that we have seen have been more "no va" thanshining white flash of a star even if the name says otherwise. With the stage set for today, we have in the EVGA SuperNOVA 1300 G2 today and this power supply once more heads back into the flagship product part of the EVGA realm like the worst of the "no go's" did once before (NEX1500 Classified). However, it has been 2 years now and 3 OEMs later so perhaps something has changed for EVGA at the high end today. Before moving on to see if this unit has gotten going today, what does EVGA have to say about the positioning of this product?
    The EVGA SuperNOVA 1300 G2 power supply is here. This power supply raises the bar with an 80 Plus Gold rating, with 1300W of continuous power, exceptional efficiency and a fully modular design. Not to mention, a first class 10 Year EVGA Warranty. The entire electrical design was engineered to be efficient, silent and optimized for the enthusiast. Take your system to the max with the EVGA SuperNOVA 1300 G2.
    With little there of real substance, let’s move on and see what we can expect when a user purchases the EVGA SuperNOVA 1300 G2 in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
