Looking to add another GTX470 card running SLI. I have a 750 watt power supply and just want to know if that's going to be enough.

Yes it will run it. you will be running it hard, but it will run it. Should be pulling 680-730 watts out of the power supplly under max load with everything overclocked.  If you have BFBC2 play for several hours, that will test the 2 GPU's and use 6 threads on the CPU. Big%20Smile

You can go big for air overclocks, you are just pushing the power supply, no harm, biggest con would be the fact it will be out of peak efficiency. While gaming, I doubt you will be pulling more than 700 watts from the power supply, so around 800-870 at the wall.
My wife ran a Corsair 750 watt PS for many years on a system with about the same power requirements, and now that power supply is now in a HTPC 24/7 use, and has been for years.
Ideally you would want a Corsair HX 850, that way, under max draw, you would be running in the "sweet spot" for efficiency, but lol you will be fine.

The power supply that came with the computer doesn't have all the power connections to run 2 470's
I have one set of 8 pin and next to that I have one set of 6 pin connectors. So I need one 8 pin to 6 pin to run both cards
