Hello people! I need your helping hand on deciding! I'm in the process of building my PC. But I have to buy the parts/components first. So far I have a Dell U2412HM (24 inch monitor 1920x1200 resolution), i5 3570k, Intel 520 SSD, and I am planning to buy a gigabyte gtx 770. But will a Corsair HX650 PSU be sufficient for this graphics card? thank you very much!
