620W-1050W Power Supply Review Roundup - Corsair, Enermax & More

• bit-tech: First Look: Enermax Revolution 85+ power supply:
  
  

  “It nudges the underside of 90 percent at 50 and 75 percent load, but drops to a healthy 87+ at full load. This matches the Corsair HX1000W at 12V weighted full load but exceeds it on the rest. The 5V standby dropped a little low, but was still well within ATX spec - there's not much to criticise at all really, it did what it said on tin pretty solidly.
  
  The biggest surprise was just how quiet it was at full load - it definitely wasn't silent and there was some obvious bearing noise from the Globe Fan (also a subsidiary of Enermax), but it wasn't intrusive and the noise was mostly a general rush of air, rather than a tornado like so many others.”

• Digit-Life: Corsair HX620W Power Supply:
  
  

  “Corsair is popular among PC enthusiasts, in particular, because of its high-performance memory modules. Power supplies of this company are somewhat less known. To fill this gap, we are going to review a number of its PSUs of various series. The first product that we have obtained is Corsair HX620W. The company positions the HX series as advanced high-performance power supplies for PC performance enthusiasts.”

• TechwareLabs: Thermaltake ToughPower Power Express VGA 650Watt:
  
  

  “The Thermaltake Power Express 650W VGA Power Supply turned out to be a superb product. The sleek and stylish exterior will look great in nearly every case. Although, if your case has a solid door on the front, then the ventilation might become a problem. With a very acceptable voltage output, this power supply will not only last a long time but will help even make your components last longer because of not suppling too much or little voltage to the device. The installation of the power supply was quite simply and painless. Being priced at $98.99, you might be better off to just purchase a large enough single power supply if you are building your computer from scratch, but if you are upgrading your graphics cards and need more power than it is something to look at.”

• Virtual-Hideout: GlacialPower GP-AL650 Power Supply Review:
  
  

  “Well, we're finally here. First, the short of it - is this a good product? Yes, but. It features high quality components, good quality cabling, a quiet, intuitive design, fairly stable voltage rails, and almost the same amount of connectors found on the recently reviewed BFG ES800 - a much more expensive and robust unit. But, I feel that this power supply is over-rated in terms of wattage. The performance is just as indicative of this as the ratings chart is - in effect, I would feel much, much more confident calling this unit a sober 500w, than an eager 650w.”
