Thermaltake Toughpower 550W Power Supply
March 16, 2006

Testing and Performance (continued):

For an idle baseline test each of the power supplies was installed on a scaled down version of the original installation. For this the following was used:

DFI LanParty nF4 SLI-DR Motherboard
AMD Opteron 148 water-cooled
2 X 7800GTX graphics cards
2 x 512MB TCCD G. Skill LE RAM
1 X 36GB WD Raptor hard drive

All other components were disconnected and the current configuration was run at stock speeds. The first chart shows how the two supplies compared on the above named hardware. In this chart we look for the voltages of the 12V, 5V and 3.3V rails as measured with a Fluke 87III multimeter (the closer to the rated voltage the better).


The next chart shows another set of voltage readings from the Fluke 87III multimeter, but this time the power supply will be placed under a heavy load. The closer the voltages remain to the idle reading will indicate the quality of the power supply. In order to achieve a well-loaded system the following was used:

DFI LanParty nF4 SLI-DR Motherboard
AMD Opteron 148 water-cooled
2 X 7800GTX graphics cards
2 x 512MB TCCD G. Skill LE RAM
1 X 36GB WD Raptor
3 X 200GB Seagate hard drives
NEC 3510A DVD burner
Asus DVD ROM
Full ATX case
4 120mm fans

The processor was then overclocked to 2.7GHz (300x9), a DVD was ripped, all fans were turned on high speed, and a data exchange of 10GB was happening from the 36GB Raptor to each of the 200GB Seagate hard drives. What about the video cards you say? I didn't leave them out; a program called 3Dmark2006 was used to make sure they stay stressed.
