I ran a 750W PSU, with ~875W coming from the wall (4 or 5 heavily overclocked 5870s), which was something like 5% above its rated capacity

I think you meant either 16% above its capacity, or 785W instead of 875:

875 * 100 / 750 = 116.67
785 * 100 / 750 = 104.67

No, I do not mean that; I specifically stated that 875 was wall-draw. There is a difference between power drawn from the wall, and power delivered to the components of your computer, and PSUs are rated for power delivered to components. A gold rated PSU will run at roughly 87%-90% efficiency (depending on the one you purchase) at > 75% load. I believe the one I had, being one of the most superior models on market, was running close to 89% or so (don't recall where I got that now, so I will take it on faith) -

.89 * 875 * 100 / 750 = 103.833333; or roughly 104% give or take.

Responses like this are part of what annoy me about the OPs model choice (I linked him a review by one of the most reputable PSU info sources detailing his PSU as a "must-pass for 1kw+"). People remain willfully ignorant of things that are so important to them as to seek out assistance. I also linked him a model that would perfectly meet his needs, save him money on his power costs, is a far superior build, as rated by experts, not retards on a forum who say "omgz my PSU didnt blow up so that means its awesomez", and cost roughly the same amount as what he purchased.

So to the OP, no, I don't give a crap about your purchase, but your mentality is what bothers me. But, as P.T. barnum said, you'll never go broke under-estimating the intelligence of people. Words to live by.
