Completely confused on compatibility for a new GPU and PSU.
Hello! I currently want to buy a NVIDIA GeForce GTX 660 and a EVGA power supply. I have a HP Pavillion P7-1414. Im sure that the PSU fits inside my PC. I'm not sure that my GPU fits inside my PC. Im sure that I have the right slot for my PC, PCI Express 2.0 x16. Im also not sure if my PSU has the right plugs for my GPU. Please help me find out if these components are compatible with my PC.
