Hoping to upgrade my current 670ftw card to one of the 800 series releases, will my current PSU be enough to power an SLI setup? I don't know if the power consumption specs have been released yet for the 800 cards, but I'm just assuming they'll be comparable or less than the 700 series.

Here's my current setup, 670 to be replaced as mentioned
PSU - Corsair HX750
ASRock Z77 Extreme6 LGA 1155
CD/DVD burner
7200 RPM HDD
830 Series SSD
GTX 670 ftw (just one, not SLI)
4 sticks DDR3 ram
2 x usb devices
2 x 120mm fans

Been trying to use this but I have no idea if it's accurate or not. So would I be safe going SLI for say the 870 or 880?

Asks about power supply, does not post what kind/wattage. This thread is going places.

Do you know how much power does the 800 series cards will use? because NOBODY else knows until they are announced.

Well this is embarrassing. Updated the OP.

I have a very similar rig to your and run SLI 670s with a Corsair CX750 no problem. As new cards are more efficient (normally, someone correct me if I'm wrong), I'd suggest that you will be fine. I plan to replace my 670s with two 880s when they drop.

I had a Antec High Current Gamer 750W PSU that could handle 680SLI with both my CPU and GPUs OCed. I read that particular PSU was tested to actually pull 900W from the wall, though.

While you probably COULD run a true 750W on this theoretical rig, you would be better off selling the 750W on Craigslist for whatever you can get for it, and drop $150-$200 on a stronger PSU to compliment your $800-$1,000 GPUs.

Sounds like I'm safe, but who knows. In case I did end up needing to upgrade the PSU (how likely would that be? not sure how close I'm cutting it with my current PSU) what sort of wattage would I be best upgrading to?
