Performance

Tested on: AMD Athlon64 FX-62 @ 2800 MHz, ABIT AT8, 2x 512 MB DDR400, WD Raptor 36 GB, Radeon X1900 XTX + Radeon X1900 XTX Crossfire

12V line stability with only one videocard active is perfectly fine. Even with two X1900 cards in CrossFire, leeching a massive 400W, the system was completely stable, but getting closer to the limits of the ATX specification.


The ripple voltage was measured on the 12V line at idle. With an amplitude of 17.2 mV it's about average.


Standard deviation is a statistical term, which tells how far away from the average the measurements are. In other words it's the average of the average.
A large standard deviation indicates that the data points are far from the average and a small standard deviation indicates that they are close within the average.


PC Power & Cooling's Silencer 750W could not hold the top spot for a long time. The Corsair VX450W delivers the highest efficiency with our standard 320W test load. You may argue that 320W is much closer to the peak load of 450W than 750W on other PSUs. But in reality most computer system are running at far less than 320W average power consumption when measured over a day of use.
