Peoples PSU size.

[Phage]

Massively overkill.

If you were SLIing 2x 580s then it'd be about right.

Damn - I used one of those on-line power calculators as well.
Can you recommend one ?

Kali, in current form, pulls ~ 160W from the wall idle and 370W at unrealistic loads. Once I drop the second 8800GTX in there and overclock everything, however, that load figure should go north of 600W.

Let us know.

Anandtech only pulled 620W for the whole system under load (crysis) with 580 in SLI, though I guess it would depend how much OCing ups things.

I haven't seen a single one that is worth using, sadly. Just read the reviews, check what the system components are, and make an educated guess/ask on these forums.

Corsair HX 850 for me as well running the below.

E8400 at 3.6Ghz (OC'd from 3Ghz)
4gb Memory.
2 x 6870 (CF'd)
1 x Raid Controller
11 Hard Drives
Antec 1200 Case with 7 fans

The PSU doesn't have too many spare connectors and from the Npower Power meter we have, I think it draws around the 700W mark.

Just hope that with my next upgrade of a Dell Perc controller, upgrade from 500gb to 1tb hard drives and new Sandy bridge processor, motherboard and 8Gb of ram is not going to push me over the 850 mark (PSU Calculators put it around the 820W mark.)

I will I'm anticipating a hefty increase when I start OCing, since it'll be a CPU *and* two power-hungry GPUs all being clocked up (under water). I'm also going to mess with my HTPC to see if I can unlock the second core then underclock it sufficiently to get complete stability with low voltage.

I'm such a tinkerer *sigh*

400w ocz psu for my main rig.

Got an akasa es450w in my HTPC powering:
foxconn cinema deluxe 2 mobo
amd 550be
4gb ddr3 1600 ram
1 500gb HD

Probably overkill but its 80+ and nice and quiet. Will probs be adding in a few tbs of HD space when I move house.

[GheeTsar]

As per sig, but 600W Tagan powering:

E8500
2 sticks of RAM
HD5870
2x Optical drives
3x HDDs

I doubt I use half the capacity but then again I wouldn't wish to go anywhere near the limit either. Hoping to upgrade CPU/mobo/RAM soon, but current house move is eating all my money.

the meter weve got at work doesnt do power leads, just individual cables,and its too fiddly to get it to work on PCs, so with what Zaks said and that chart kalniels posted, im revising my estimaed usage up to about 320w.

maybe oneday - next time its in for dust removal, using the compressor - i will check this.
