Gearing up for Windows Vista, Aero Glass, and DirectX 10, power consumption for 3D graphics is likely to increase by 20 to 50 percent. Any doubters need only look at published estimates for the next generation of 3D processors from ATI and nVidia. Those that thought increased efficiency of new system processors would mean they could hang onto their old power supply are going to face a harsh reality: We still need more power!

Fortunately, 500W+ power supplies have been working their way into mainstream status for a few product cycles. In a time when 500W seems as though it may be barely adequate, 650W should be plenty!

Following up on our recent NZXT Apollo case review, the youthful brand sends its Precise 650W power supply. But how precise is it? Can it meet SysOpt standards for quality and value?
