AnandTech checked out another power supply from Zippy's Serene lineup this week, the GP2-5600V. This 600W PSU has an advertised efficiency of 86%.
When companies target the high-end enthusiast market, there are often expectations about what is necessary as well is what is actually required. Many enthusiasts appreciate getting some extras, but at the same time there are others that already have all the zip ties, badges, lanyards, etc. that they need -- anything else is just clutter and extra cost that could have been spent on improving the quality of the primary component. Zippy chose to target the latter group of enthusiasts, and we found just the needed items for installing this PSU. Hopefully that means that Zippy focused more on the inside of the PSU, which is a perfectly acceptable approach if it holds true.
Check out the full review over here. AnandTech says the GP2-5600V from Zippy performs really well and is an absolute winner in the efficiency race. It's the best one they've ever seen with an efficiency of 89% - which is even 3% better than advertised.
