Installation and 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 Xeno Pro NIC, and a Foxconn-made nVidia 8800 GTX inside a Cooler Master Cosmos S case.
I’ve included graphs from the Cooler Master Real Power Pro 1250W power supply review I did a while ago using very similar hardware. The differences since are the addition of the SSD and the Killer NIC, and subtraction of a Creative X-Fi Gamer sound card. The graphs from the Sparkle 1250W are on the left and graphs from the Cooler Master Real Power Pro 1250W are on the right.
Spot checks put the 3.3V, 5V, and 12V rails at 3.26V, 5V, and 12.22V respectively while idle and 3.23V, 4.97V, and 12.22V under load.
The 3.3V rail on this waved a little (1.52%), but was still within acceptable range. It bounced up and down a little during the middle of the test, but was more stable at the end.
The 5V rail ripple was fine (~1%), but the voltage was up and down through the test, not really remaining consistent.
The 12V rail rippled, but was largely stable throughout.
Noise-wise, I didn’t notice an above-average amount of noise produced.
