Hey guys,

I have a Asus crosshair v with fx8350, coolermaster 212evo cpu cooler, 8gb vengeance ram (2x4gb) 250 Samsung ssd, 1tb 7200rpm HDD, 1 x Asus gtx 770, standard dvdcdwr drive, 4 x fans and 4 x USB devices and few LEDs here and there. That is all run from my OCZ fatality 750w bronze PSU 80+ bronze.

My question being could that handle a second gtx 770 in SLI? I've done a few PSU calculators but they all come out different so I'm not really trusting them!

Has anyone got the same sort of rig and running it fine or know for a fact it would be ok?

Thanks!
Mitch

A pc with a GTX 770 in it needs a minimum of 42A on the 12V rail and 600W in total. http://forum-en.msi.com/faq/article/power-requirements-...

770's in SLI need 850W minimum http://www.realhardtechx.com/index_archivos/Page362.htm

Make sure you have a good power quality supply - from Tier One on - http://www.tomshardware.com/answers/id-1804779/power-su...

I agree with i7Baby, an 850 watt PSU is the way to go for SLI. 600 Watts for one GTX 770.

Yeah your PC with one 770 isn't using more than 400 watts so you should be good to go with an sli setup as long as you have the PCI-e connectors to feed those beasts.
