Performance

The UL number E166947 reveals that the PSU is made by OEM manufacturer Enhance Electronics for Cooler Master.



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

While the 12V line is very stable, the 3.3V and 5V lines fluctuate quite a bit under load. All voltages remain within the limits of the ATX specification however, so there is nothing to worry.


The ripple voltage is exceptionally small with only 6 mV, which is one of the best results I've seen so far.


For easier comparison between power supplies we put the (normalized) line regulation standard deviation into graphs.



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.
So the smaller the standard deviation is, the better the line regulation.
