Performance

The UL number E144195 tells us that this PSU is made by Sirtec International Co. Ltd.



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
Voltage stability is good, the 3.3V line flucuates a bit, but still stays inside the limits set forth by the ATX specification.


The ripple voltage was measured on the 12V line at idle. With an amplitude of 17mV it's quite ok.


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.


Sirtec can be proud of achieving such a high efficiency with their Rock Solid 1000W PSU. The immediate benefit of a high efficiency is less heat, which means less cooling required. Sirtec did a great job keeping the fan noise down as well as we can see on the next page.
