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 Xeno Pro NIC, and a Foxconn-made nVidia 8800 GTX inside a Cooler Master Cosmos S case.
I’ve included graphs from the Silverstone Strider Plus 750W power supply review I did a while ago using very similar hardware. The graphs from the Thermaltake Toughpower XT 775W are on the left and graphs from the Strider Plus 750W are on the right.
Spot checks put the 3.3V, 5V, and 12V rails at 3.3V, 4.96V, and 12.04V respectively while idle and 3.26V, 4.95V, and 12.10V under load.
The 3.3V rail held up pretty well, rippling only 1.4% and staying quite stable throughout the test. The Thermaltake definitely beats out the Silverstone on this rail, in both amplitude of fluctuations, as well as frequency.
The 5V rail was also quite stable, rippling only 0.40%. The Strider took a drop in voltage during the test, and the Thermaltake didn’t.
Now the 12V rail is where the the ripple was the same (0.58%), but the Thermaltake had some stability fluctuations. This was likely during the heavier sections of the graphical tests.
The noise level is nothing out of the ordinary. The fan stays active following shutdown in order to quickly cool the unit, extending its life.
