Testing

For testing power supplies, we get together the most power hungry of all our hardware, get it all plugged in and then test the rail's outputs at idle and at load to check their stability. However, since this PSU is rather large in it's wattage, we decided to use our hillbilly testing setup. This involves placing our AM2 and Conroe systems very near each other and having the Olympia not only powering the entire C2D rig, but also the GPU, hard drives, CD drives and all fans from the AM2 rig.

Testing is performed using Asus Probe. A multimeter is used to check accuracy of readings.

The pieces of hardware that the OP650 powered were:

Core 2 Duo E6600 @ 2.7ghz
Asus P5W DH Deluxe
MSI 8800GTS
x1950 Pro 512mb
2gb OCZ Special Ops. Urban Elite @ 900mhz
1x 36gb WD Raptor
2x 80gb WD Caviar SE
2x LG CD/DVD Writer combo.
3x 120mm Noiseblocker fans
2x 120mm Akasa fans

Our hillbilly rig setup

Result

As you can see from the above results the Olympia is very stable and the voltages only fluctuate slightly on each rail. There is also very little variation when switching from idle to load which is another indication of a top class PSU.
