Should I upgrade my psu?

post #1 of 7
Thread Starter 

I recently built my rig (specs below) and plan on adding another evga gtx 580 1.5gb, and in the future install a corsair h60 or h70.

I seen a video on youtube from linustechtips


Showing you can, but im not so sure. Would it be safe to add another 580 to my system?
I do plan on upgrading my psu later but would like to upgrade to dual gtx 580's.

Edit: My cpu is not oc'd but do plan to to about 4.0ghz, my gpu is not oc'd as well.

Yes, an 850w psu will be enough for two 580s. However, if you want to overclock you might want to look at something in the 1000+ range.

Your HX is more than fine for SLI 580, even for overclocking

just did a quick psu calculator check with 3 580's and it recommended 830 watts. So 2x 580s with your psu will be fine.

No, HX850 is a beast

That thing could handle a 2600K and 3 stock 580's if you weren't doing hardcore benchmarks, although I wouldn't want to lol
