Simulated Load Results (Data)
OK, so we've seen the graphs over on the previous page. Now here's the data that they were derived from.

To repeat what's already been said on the previous page, the Silver Power SP-SS750M is one very stable PSU across all tests including the Max load test where it's pushed to an impressive 936w. The only minor issue I'd like to see rectified is the relatively high idle voltages that give the feeling that Silver Power haven't spent much time fine tuning the unit. As for the rest of the results: efficiency is great, exhaust temperatures are low and cross-loading the unit had little negative effect. Nice.

The greatness also continues on to the ripple results where the +12v rail seems to be impersonating a pancake. Seriously though, 30mV of ripple on the +12v rail at full load is quite possibly the best result seen yet on OC3D since we began using the oscilloscope. The +3.3v rail is equally as awesome with a maximum ripple of 18mV in test 4 and only slightly higher in the Max Load test. The +5v rail results seem to go hand-in-hand with the +12v results which may suggest that only the +3.3v rail received the DC-DC VRM treatment whereas the +5v rail was derived direct from the transformer. But regardless the results are still well within ATX specs.
Now on to the conclusion...
