Hey TH. I'm upgrading my pc so I'm mixing some parts together for my fiancee's computer because they're both nearly identical. Here's the spec
ASUS M5A99FX PRO R2.0
AMD FX-8320 8C 3.5GHz Black Edition
Corsair 8GB (2x4GB) CL9 1600Mhz VENGEANCE LP White
ASUS GeForce GTX 760 DC2 OC 2048MB
Fractal Design Integra R2 750W 80+ Bronze

I've looked through the forum and the sli sticky but I need some further help. Will that psu be enough to power the computer if I add an identical gpu? Cable wise and not power wise, that is. The cable that's connected to my gpu is unique, there's no cable like it from the psu. It's marked pci-e. There is another cable (2x3) that fits on one side but it's only marked as "B". Will that work aswell? Thank you in advance, I will respond quickly.
