I just bought a gigabyte GA-770T and I am trying to install it (as we speak).. I'm not too familiar with power supplies, etc.

Do I need to install both the ATX plug and the ATX 2x4 12V? I have one ATX plug that fits no problem, but I don't seem to have a second 8 pin plug.. What am I missing here?

PS, power supply = 430W Thermaltake model: XP550NP

Help is much appreciated! Thanks in advance.

Yes, you have to connect both the main ATX connector and the CPU power connector. I'm sure your POS power supply doesn't have an 8-pin connector, but you can just use a 4-pin connector. Check your motherboard owners manual to see which four pins to use. The system doesn't have a chance of working without both connections plugged into the motherboard.
