Corsair HX650 enough?

post #1 of 39
Thread Starter 
So I just started receiving some of my parts from newegg, amazon, and the such. What I ended up going with is what I have in my sig rig. Just curious if a HX650 will be able to comfortably run this system. Just would like to know before I put it altogether.

Thanks

Umm its a little iphy to say the least. You have no overclocking headroom whatsoever thats for sure. You will be pretty close to the max power consumption.

Bull****. A GTX 580 rig can comfortably run on a good 500w PSU.

PSU calculators vastly overestimate the amount of watts you need.

Lol chill out there. He can run it but what about overclocking?

Also a stock 580 at load consumes 363watts.
A stock 2600k at load @ 3.9 is at 184. IF you push it to say 4.6 that jumps to 238.

Thats why I said it would be cutting it close. And thats gpu stock, imagine overclocking that too.

a little bit, but you would want to know if your setup was using your psu to the max or close to the max, wouldnt you? I think psu calculators provide a pretty fair indication.

Well overclocking would definitely be a must. Not gonna get a i7 2600k and not overclock it

Overclocking would be fine on a 500-550w as well. The GTX 580 is a 250w GPU.

Your looking at overall power levels, the gtx 580 consumes about 240w at full load last time I checked, though I can't be 100% sure.

@OP You will be fine with a 650w, you have plenty of overclocking headroom.
