850 watt unit good enough for 2 580's?

post #1 of 5
Thread Starter 
So I just wanted to know for the next time that I think about upgrading my GPU if my 850 watt unit (in my Black and Blue build in my sig) will be enough to power two overvolted, 1 GHz GTX 580's. I've overvolted my current 580 to 1.213 volts, and if I get another I will surely do the same? Is this enough wattage for two of them and an overclocked 3570k?

It should be enough but again it depends on how much you have overvolted the cards

Unfortunately, no. I think that you'd need a good quality-made 1000W or higher. If you had them at stock, then it would be plenty.

 

I'm assuming that overvolting them that high (Afterburner is limiting me to 1.15V) increases the power consumption by a LOT.

Alright, thank you very much. I didn't think it was going to be enough, so it is good to know so that I won't be going SLI in the future. I have overvolted the card quite a bit, to the maximum allowed voltage actually, so I think I will stick with a single-card set up in the future. Thanks guys!

Or, just upgrade to the GTX 780 or R9 290.
