Hi everyone !

I planning to upgrade my pc with second GTX 780Ti (SLI) and was wondering should I get a 1200 Watts power supply instead of 1000 watts one.

Here are my specs:

CPU: Intel i7-4770K
Cooler: Phanteks 12dx
Motherboard: Gigabyte G1 Sniper Z87
Memory: 16 GB Kingston HyperX Furry
Video card: GTX 780Ti
Power Supply: Corsair RM 1000 Watts 80+ Gold

Thank you all in advance !
