Performance

The UL certification number E319019 reveals that this PSU is made by HIPER.



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

All voltages are very stable and show only slight deviations when load changes. I would like to highlight the 12V line here which is the most stable I have ever seen in all our recent PSU reviews.


The ripple voltage is OK with a range of 18.4 mV.


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.
