Hi, I just bought all of my new parts for my first build. I'm still pretty new to all of this so I kind of just got what I thought was good. I checked compatibility with everything except psu with the motherboard. I know that sounds crazy, but I'm not sure. I have a Corsair CX500 psu, and a Gigabyte F2A55M-S1 motherboard. I plugged the 24 pin connector but it wouldn't turn on. There's the other 3 cords as well, the 2 pci-e cords and the cpu cord but the cpu cord had six pins and the slot what I thought where it was supposed to go only had 4. I'm completely lost and so upset. I really need your help so I'll take whatever you guys have.
