Installation & Use
I used OCCT Perestroika in conjunction with Everest for benchmarking and monitoring on Windows 7 64-bit after installing into my standard testing rig with an ASUS M3A32-MVP motherboard, Athlon X2 6000+, 8 GB of DDR2 RAM, three SATA hard drives, a Kingston V-Series 128 GB SDD, a Killer 2100 Gaming NIC, and a Foxconn-made nVidia 8800 GTX inside a Cooler Master Cosmos S case.
Spot checks put the 3.3V, 5V, and 12V rails at 3.3V, 4.89V, 12.3V idle and 3.28V, 4.87V, 12.3V under load.
I’ve included comparison graphs from the test of the Sparkle Gold Class 1250W I reviewed recently. The Silent Pro Gold graphs are on the left, the Sparkle on the right.
The 3.3V rail rippled more than the 5V and 12V rails, but it’s still within acceptable limits and is quite stable despite some spikes between the 20th and 24th minute of the test.
The 5V rail undervolted by as much as 3% at times during the test. This is still within our +- 5% range, but it’s a little close for comfort.
The single 12V rail overvolted by 2.9% at times, but held a pretty steady 12.29V.
The noise level was nothing out of the ordinary.
