I just bought a second gtx 580 on ebay and I am wondering if my power supply will handle the load. I have been looking into this for over a year now and everyone gives me a different answer. 

So the question is with the configuration below will I have a safe and stable system? I will not be overclocking with two cards in ever. I have to much money in this to louse it now. 

My system

corsair HX 850w atx 12V

intel 2600k stock clock

corsair H100i

kingston hyperX 1600 8GBs

corsair force GT 60 GBs SSD

ECS gtx 580 stock

MIS P67A-GD55 motherboard 

WD blue 320 GBs 7200 rpm HDD

Windows 7 Professional 64 bit

New card- MSI gtx 580 twin frozer 2/ OC


Thank you to everyone for your help.

That PSU could almost power a sauna heater.

You have enough juice.

technically Nvidia has not certified this PSU for gtx 580 sli use. And I wonder why. I also think it should be ok, but i suppose only time will tell. I should get my new gpu here in a few days.
