1KW PC Power & Cooling SLI power supply tests

[eva2000]

Further load testing this time Opteron 148 @3102mhz at 1.6v with HIS X1800XT @756/900 with GPU = 1.45v (1.48v) running 3dmark05 with MBM5 running in background.



MBM5 results see:
3.3+ = drop from 3.25v to 3.23v (0.615%)
5+ = drop from 4.97v to 4.94v (0.603%)
12+ = drop from 12.27v to 12.14v (1.06%)

Digital multimeter read the 12+ rail as:

LOAD:
12+ = at start of 3dmark05 drops from 12.19v to 12.16v and stays steady at 12.16v throughout the GT1, GT2 and GT3 tests and then jumps back up to 12.18v for cpu tests in 3dmark05.

So for GT1-GT3 = 0.247% drop and CPU tests = 0.082% drop.
