It really feels like centuries since i last reviewed a power supply unit and so todays review is not only the first of its kind here but also the first one i test with a new test rig (well not actually new since the components are pretty much what I’ve always used, just on a different test bench). I am sure that by now most of you are well aware about the reasons as to why people should always prefer brand name power supplies over noname ones but for all of you who are not i can point the 3 perhaps most important ones which are clean and stable power for your system (translates to more life for your computer), higher quality components (more durable) and finally lower noise levels (who likes noise?). So today on the new test bench we have the latest Antec HCG-620M, a 620 modular unit targeted towards the mid-end segment of the market and more specifically gamers.
Today we look at the latest power supply from Corsair, the Professional Series AX1200i. This is the first desktop power supply to use a digital signal processor (DSP) to digitally control the power output. Corsair class the AX1200i as the ‘ultimate performance power supply for a dream PC system’. This fully modular design has over 100A available via the +12V output and has achieved 80 Plus Platinum certification.
he Cooler Master V-series 1000W power supply is the latest flagship model PSU from Cooler Master. The CM V-series also includes 700W and 850W models, all of which use a fully modular design like the 1000W model. Ditching the Silent Pro Hybrid’s Enhance OEM, the new V-series is based on a new Seasonic design and is 80-Plus Gold certified. Unlike other power supplies including previous Cooler Master models, the V-series power supplies use a new premium-grade 135mm Fluid Dynamic Bearing fan from Protechnic Electric Co. that runs quieter and longer lasting. The 1000W V-series PSU from Cooler Master supports up to Quad-SLI/Crossfire with its eight 6+2-pin PCI-E connector and has 83A on a single +12V rail. The Cooler Master V1000 power supply uses 100% Japanese capacitors for stability and high-reliability with protection for over-voltage, under-voltage, over-current, over-power, over-temperature, and short-circuit protection. The CM V-series 1000W power supply also has MTBF rating of >100,000 Hours and carries a 5-year limited warranty.
In the next few months Enermax will be refreshing their offering in the mainstream / low end areas bringing the Triathlor to market. Today we have the 550w model on our test bench to find out what it offers for those on a limited budget.
The Thermaltake Evo Blue 2.0 850W Power Supply is 80+ Gold certified, comes with flat, flexible modular leads, has a quiet 140mm fan and a 5 year warranty. What's different about this PSU is the turbo switch, which offers up another 100W of power. A great PSU for an enthusiast on a budget.
Be Quiet’s L8 500W PSU from their “Essential” line boasts a 120mm silent operating fan. The Be Quiet L8 500W PSU is 80 plus bronze rated and is compatible with ATX 12V V2.31. The PSU utilizes two independent 12V rails, which reduces crossover effects and improves voltage stability. The housing of the L8 is painted all black, giving it a sleek appearance that will fit well into most cases.
Seasonic is releasing the third generation of their power supplies with the 80 Plus Gold certification, dubbed the X-Series KM3. Let’s take an in-depth look at the 650 W version of this new generation, which comes with a fully modular cabling system and a single +12 V rail.
OCZ have had many successes in recent years, and one of the most noticeable would be their StealthXstream series of power supplies. Today we are looking at a very competitively priced power supply in their new value range, the ZS Series 550W which replaces the StealthXstream 2.
It has been awhile since our last PSU review and today we are glad to introduce you another interesting, high performance PSU. Our hero today is Arctic Cooling Fusion 550R which is a 550W ATX2.2 PSU. Besides green and high efficient, Arctic Cooling Fusion 550R has another unique feature; an ultra quiet 80mm fan. Let us go through further.
The Antec High Current Gamer power supply series is comprised of 400 W, 520 W, 620 W, 750 W, and 900 W models, all with 80 Plus Bronze certification, single +12 V rail, and no modular cabling system. Let's take a look at the 520 W model.
