However, even so, your system draws far less than most people think. You *could* run another GTX580 on your PSU, though I usually recommend a 750W for SLI GTX580s.
Well, i'm definitely not trying to kill my psu in a hurry, I want to keep this system for as long as possible.

Should I just stay away from sli in the future unless I get a higher wattage psu?

Huh? Folding is much more stressful than any benchmark.

Lynx would like to have a word with you.

EDIT: Never mind, you said bench, not burn test.

There's a million other variables that go into that. How often you turn on lights in the house/run AC/having the computer on different amounts of time during the month...

Typo sorry, I meant stress test (power/stability benchmark, if you will, not like PCMark).

yes I know but depends what your testing for? Is it to see what a pc pushes out and to see what it will cost a person is this correct. Now your pc will never run on full load 24/7 it will go up and down for the full month or till you get the Powerbill. But will the meter give you your avg usage? Now does a persons Powerbill have huge differences every month or do it stay around the same amount more or less. Not exactly the same but a small difference in it. Now by monitoring your bill a month or 2 if its up you can see if it stays at that amount more or less. So you can take the difference and compare it to what you worked out with the meter to get a avg more or less. Not saying its the best way just a thought coz the bill matters in the end

Are you kidding me? i'm running 3x gtx580s and folding@home gets me to like 875 watts, along with cpu folding.

650 is enough... You'll draw 550-600 watts at full..

As for whether you could go 580 SLI on that PSU? I'd personally be a bit wary, my VX-550 could theoretically have taken two HD4890s in CFX, but it blew up after a month or so of having that, it's mostly about the +12v rail and how many amps you use on it.
A VX550 can take two 4890's... if it blew up then there was something wrong with it.

Edit: An X-650 would be fine on two GTX 580's for just gaming load... but I'd rather a 750w minimum.

Edit 2: I think your Kill-a-watt results may be slightly innacurate, too. Around 450w DC would be a more realistic number.

A VX550 that was also taking 4 HDDs, an overclocked quad and was ~2-3 years old.

It had the wattage but the 12v rail was overloaded is what I think, although I wasn't stressing my rig when it did blow up.
