The biggest power uses in my computer are my cpu amd fx 6300 and my gpu gtx 770 4gb windforce 3x from gigabyte. My psu is a tx 750w from corsair. Well what i want to know is if it'll be enough for a second gpu that would either also be a gigabyte one or a zotac one. If its not enough could you please recommend a wattage that would work well thank you to anyone who answers.

The 770s use ~250W peak each and the rest of your system should use about 150W peak, which leaves you with about 100W of headroom on the PSU. A little tight but it should work since you are never going to simultaneously hit peaks on all components all the time outside Prime95+FurMark.

Thats what i was thinking i was also thinking that not many games couldn't possibly get 100% usage out of two 770s hell only far cry 3 and the evolve alpha consistently give me 100 usage on one card so if theres two they collectively may use a little bit more than 1 maxed out.. If i do have problems I guess i will upgrade the psu hears hoping all goes well.
Also thanks for all the answers I got.
