Doubling up on my gpu - need power supply suggestions
I'm am currently running a MSI gtx 680 twin frozr 4gb card and have found 2nd one on eBay for a good price (it's already on the way, so don't tell me I don't need it or just to switch to the 780). I'm looking to double up these in SLI but I'm going to need more juice. I currently have a 700W 80 Plus PSU. What would you suggest for a PSU? I was thinking 900W 80 Plus Gold.

actually the 700W might just be enough. each card uses about 170W so depending on the rest of your config it may just work without a psu upgrade
edit: sure, a 900W psu will be better but you can try without upgrading and if there's any instability you upgrade the psu
Well, I'm running a ECS Golden Z77H2-AX motherboard with an Intel i7 3770K, 16 GB Ram, and a CM H100i liquid cooler. Maybe I will try to run it without upgrading the PSU. I'm just a little concerned about the efficiency of my current PSU.
just 80+ isn't great so upgrading it wouldn't be a bad idea. if you do 80+ bronze should be the minimum you're looking at.
