eTeknix has been absent from the world of power supply reviews for around 18 months. Ever since our Sunmoon ATE SM -268 Load Tester broke we have been left without enough test equipment to do a “proper” power supply review. By proper we mean not simply loading the system with VGA/CPU components and taking motherboard readings with programs like OCCT, neither do we find using a multimeter is accurate enough. Our definition of proper power supply testing at eTeknix has been to use a dedicated power supply load tester. Just a week ago we took a trip to Hamburg in Germany where Enermax kindly allowed us to test a whopping 29 power supplies on their Chroma power supply load tester.
The first of those power supplies we tested for review was the XFX Pro 750W Black Edition fully modular power supply. This power supply from XFX is actually manufactured more or less entirely by Seasonic and is based upon the Seasonic X-750. XFX is actually one of Seasonic’s OEM partners. With 750W of continuous power over a single 12 volt rail the XFX Pro 750W power supply is designed to power the most demanding gaming systems with a single ultra high performance GPU or a pair of mid-high end GPUs.
Furthermore the XFX Pro 750W Black Edition uses a fully modular design meaning it is entirely capable of giving you a clean looking system. What’s more impressive is every cable is fully black while all cables, except the motherboard 24 pin, use “flat” black cables for easier cable management. Furthermore the power supply features a hybrid fan switch that allows you to switch between an “always on” or “hybrid on/off” fan mode. The always on mode means the fan always spins and varies with temperature while the hybrid on/off mode allows the fan to turn off at low loads. The option to choose is indeed a very nice feature.
On top of all that the XFX Pro 750W Black Edition power supply is one of the most aggressively priced power supplies on the market and comes with a 5 year warranty, yet has performance that beats most of its competitors if the Seasonic X-750 is anything to go by. But without any further ado, let us proceed on to this XFX Pro 750W Black Edition power supply review and sea how this product stacks up.
After having reviewed XFX’s Pro 750W Black Edition power supply I have high expectations of this next power supply from XFX. The XFX Pro 650W Core Edition power supply that we have here today is XFX’s attempt at a well priced power supply powerful enough for most high end single and dual GPU gaming systems. The raw design, like with all XFX power supplies is based on a Seasonic OEM design. This particular unit boasts 650W over a single 12 volt rail and is cooled by a 135mm fan.
The XFX Pro 650W Core Edition power supply features 80 Plus Bronze Certification and a non modular cable design. Like with all gaming products XFX have gone for a rugged looking black design. XFX state that this power supply is certified for SLI and CrossFire. Additionally XFX say that this product uses Japanese Capacitors and you need not worry yourself about its quality because XFX are backing it with a huge 5 year warranty.
Fractal Design's flagship power supply delivers plenty of power at a good price. Read on the see how well it performs under our tests.
Within the last decade we've seen the 80Plus certification become a widely accepted standard and further expanded into Bronze, Silver, Gold and Platinum levels as efficiency improves. Combine lower hardware power requirements with more efficient power supplies and we start to see what had been a steady upward trend in power supply size begin to level off and perhaps even decline. Where 750W or 850W may have once been the norm, we're now seeing units in the 500W to 650W range become more popular.
Today we take a look at another power supply from Corsair and we have the GS800 (V2) “Gaming Series” power supply in for testing. The GS800 boasts 80 Plus Bronze Certification, a bucket load of connectors, a 3 year warranty and more uniquely customisable LEDs and plastic strips (though the strips are sold separately). The GS800 is in this regard one of the most unique PSUs on the market in that it allows you to customise its colour scheme. Though by default it comes with a blue LED and blue strip to match the blue sticker. The Corsair GS800 uses blue, white and red LEDs which you can see below. These are switched between by using the LED switch on the rear of the power supply, accessible from outside the case.
Other than that there isn’t that much else to discuss because this is pretty much an 80 Plus Bronze non-modular PSU with some extra bells and whistles. Let’s proceed with the testing and see how good the GS800 (V2) from Corsair performs.
We take a look at one of SilverStone's lower wattage offerings to see if their low-end is just as good as their high-end. Let's dive in and see.
The Seasonic Platinum 660W, 760W and 860W are basically perfect power supplies. They have the best low-load efficiency we've ever seen in this segment, the efficiency at higher loads is also good, their ripple is outstanding and the semi-passive design makes them inaudible in most circumstances. Had some of the cables been a little longer there would have been nothing we could complain about.
Das Enermax Revolution X't soll gegenüber dem Revolution87+ mit niedrigerem Preis punkten, ohne auf wesentliche Features zu verzichten. Wir testen, ob die Rechnung aufgeht.
BeQuite! Is a German company that specializes in silent power supplies and maximum cooling solutions for PCs. They have been manufacture of the year multiple times and are the #1 company leading in Power Supplies. BeQuiet! Has finally decided to share they silent and cooling solutions with us and we are extremely excited to be one of the first to review this amazing power supply. The PURE POWER L8 600W. (80PLUS Bronze/AMD CrossFireX)
At first glance to most people power supply units may not seem to have advanced much compared to the ones we used to check almost a decade ago but in reality most of their interior components have, some just a bit and some quite a lot. Regardless of that however the same "principles" that applied even 10 years ago apply today (perhaps even more so due to the cost of multi-GPU setups) and so we always recommend using good quality power supply units to avoid any unpleasant issues for your hardware and of course to provide optimal stability (especially for overclocked systems). Now as many of you are well aware the safest and fastest way for consumers to "rate" a power supply unit is to check its 80 Plus efficiency certification and although the top of the line Titanium models offer the highest possible electricity savings currently and thus make use of the highest quality components they don't land far from the Platinum and Gold ones. The ToughPower DPS G 1050W model is one such 80 Plus Gold certified PSU and we have it with us today to see how it ranks in the market.
