Not sure if my PSU can handle new GPU

[FivosG]

Hello,

So when I started building my PC I decided not to buy a GPU and buy it in the future. I got myself a Corsair RM650 Power Supply, Intel Core i5 4670K and overclocked it to 4.2GHz, a Maximus VII Hero motherboard from ASUS, Coolermaster HAF 932 Advanced Case (4 fans), ASUS DRW-24B3ST Optical Drive, Samsung 840 EVO 250GB SSD, 1TB WD Black HDD. Now I would like to buy Gigabyte's GeForce GTX 770 OC WindForce 3X 2GB GPU but I'm not sure if my Power Supply could handle that many components.

My friends keep telling me that 650Watts are over enough unless I want to do SLI (which I don't want to do) but I'm still not sure so I decided to ask the community.

So are 650Watts enough?

DO not do 3 way Sli, or even 2, You would be better getting a single better card especially in the long run, and 3 way Sli isnt optimized very well and isnt that fast compared to 2, 650w wont be enough for 3 way, and probably not 2 way. I would get a 850w psu anyway since that Psu isnt very efficient.

(that psu could do 1 card easily)

I think you didn't understand me well, I won't do SLI, I just want to buy one Gigabyte GTX 770 along with my other components since I dont have a graphic card right now but I'm not sure if 650Watts would be enough

Yes, it can do it - and your friends are right that you should not try and do SLI with a 650 watt power supply

Sorry i was confused you put "Wind force 3X" I got confused. But as the person above said you can do it, but it would be good to get a more efficient psu later on.
