Interesting but that's the input draw of the PSU, from the mains socket. What the psu is putting out will be a factor of it's efficiency. For example say it's 80% efficient then output watts become 500w x 80% = 400W. To further complicate matters Efficiency varies wirth a) level of output & heat(hotter reduces efficiency)

Yep, so if the PSU is only doing around 60% efficiency at lower wattage, then the results will be even lower...I think Ive done this right;
580w x 60% efficiency would mean 348w
Even 580w x 85% efficiency = 493.
Does that look right?

Yes absolutely in line with what I'd expect

correct This shows how efficiency varies with load Enermax Galaxy 1000W Efficiency TestingYep, so if the PSU is only doing around 60% efficiency at lower wattage, then the results will be even lower...I think Ive done this right

Those figures for efficiency are a bit different to what was said here...anyway, the bottom line is that, even with 85% efficiency, I dont need more than 500w to run flat out with a fairly decent overclock..interesting

One thing to note in both of those Galaxy efficiency ratings is that the input voltage used was ~120V. Since you're on 240Volts Clunk, you can expect slightly higher efficiencies that are quoted in those articles.

Thanks. Now to underclock this quad and see what I can get the overall usage down to

Mind putting your results in the thread I've made Clunk? Would be nice to have them all in one place

Would be nice to build a reference for everyone to look at
Ok, will post my results this evening sometime.
yep that's a good point, as metioned in the review i linked. Not a clue why there are differences.Since you're on 240Volts Clunk, you can expect slightly higher efficiencies that are quoted in those articles

Does anyone else find that the overclock voltage will only go to one decimal place now. It used to be more. Going up in 0.1v is quite a difference.
