Here is my problem I am a first time PC builder I am currently in the middle of my build right now. I have the CPU installed, Cooler Master EVO 212 installed, Memory installed, and Video card installed. I am about to do a test boot I am doing this outside of the case right now before I install it to make sure no parts DOA or etc... I already have the CPU fan plugged in, Motherboard power plugged in and now I am about to plug in the Video card to PSU but realize that I am not sure which to use 6 pin or 6+2 pin and why or why not to use one or the other. Can someone please explain it would be greatly appreciated. The PSU is Rosewill Hive series 750 watts and the Video card is 7870 2GB GHZ series. Thanks in advance
