PSU recommendations?

[olijng7]

Hello people,

I just built my new comp and I am satisfied with it and I love it, but I was just wondering that if I was to get another video card to crossfire, if I would need a new psu with a higher wattage. Here's my rig:

i5-3570k @ stock speed
ASRock Z77 Extreme4
Thermaltake 750w SMART
Sapphire HD 7950 w/ boost
Samsung 830 ssd 128gb
1TB hdd
4GBx2 corsair Vengence 1600 ram
cd-rom (I think) optical drive
1x 120mm fan
2x LED 120mm fan
1x 80mm fan
CM Hyper 212 EVO

Tell me if I left anything out. Also, I may want to overclock my proccessor sometime.

If you have two sets of PCIe power cables (for 2 GPUs) then you should be fine. I have two GTX 560 Ti's running on a 750W Corsair PSU
