Hello, I'm considering getting a 2nd gtx 680, however I'm curious if my current psu can handle two. I don't have my processor or my current gpu overclocked. I do however have an corsair h100 liquid cooler, and 16 gigs of ram (if this matters).

PSU: http://www.canadacomputers.com/product_info.php?cPath=3...

Corsair TX750M Power Supply (CP-9020003-XX)
Voltage +3.3V +5V +12V -12V +5Vsb
Max. Current 30A 30A 62A 0.8A 3A
150W 744W 9.6W 15W
750W
Dimensions: 5.9"(W) x 3.4"(H) X 6.3"(L); 150mm(W) x 86mm(H) x 160mm(L)
MTBF: 100,000 Hours

Will I need to swap to a more powerful psu, or will my current one suffice?

750 is easily enough.

If you use this psu calculator considering your components, the result is 664W (overclocked processor & used 680x2 to simulate gpu OC:

All points out to 750W being more than enough.
