Ok, so basically I've invested in a new power supply and graphics card. Now everything was going smoothly until i put in the 20+4 P1 plug to the Mother board. Theres two other plugs, thats it... One is a two 4 pinned (or w/e) plug, they're pretty much tied together so its eight. labeled P3. now I THINK this plugs into the 4 pinned (or w/e) plug on the motherboard (thats right up near the power supply). But the other 4 pinned part of that plug throws me off. The other plug is labled "8pin(PCI) on a tag, and the atual plug is labled "PCI-E" (E is for "Express"). Where does that go? i cant figure it out for the life of me, it a 6+2 plug (one 6pinned plug tied to a 2 pinned one). And also it seems as if I'm missing plugs, there's no SATA cables to plug into the disk drive, or that other thing (If you haven't figured out by now I am NOT computer savvy). The power suply is an Antec BP550 Plus.
