I have a gaming PC that I am adding a second graphics card to, was just wondering if the power supply listed would be adequate. I've tried checking myself but some of the information goes over my head.
- Graphics cards are actually Palit 770 4 gig versions, but they don't seem to appear on the website. Don't think it'd make a difference but might as well mention just in case.

Even with all these components pegged at 100% that PSU would hold just fine. However it's always nice to have future headroom though, so 850w is the way to go.
