My kill-a-watt is telling me I'm currently using 976 watts (assuming that is true,
So, the ~800w was an approximation using the efficiency graph for the hx750.
976 * 85 = 830. So, I approximated by saying ~800w.
And as far as system specs, I don't really like having them, this was just a general question of one or two power supplies, but I do realize that can vary depending on the setup.
But for curiosities sake:
My current setup (976w reading):
CPUs: 2 x E5620 (4ghz)
RAM: 6gb Mushkin
GPUs: 2 x GTS 450, 1 x 470 (all overclocked)
HDD: OCZ vertex, 2tb WD Green, 500gb F3
And then I will be swapping out the GTS 450s for GTX 480s, adding 6gb of ram, and the loop (I know the loop won't use much).
I would bet my hx750 could handle the upgrade, but I would be over taxing it, and I want to ensure my overclocks remain stable and that I don't want to kill the psu. I could use a 1000w, but I would like to use a more efficient amount of wattage out of the psu.Edited by hoth17 - 12/19/10 at 2:25pm
