I got a cyberpowerpc off the shelf one at costco. I saw that it didn't have a graphics card, but I could add one later on. i found the GTX 760, and now Im getting one next week. I looked at the reviews from costco and someone said that he added a radeon 6870 which required 2 six pins. Making sure, today I too a look into my system and I couldn't find any PCIe psu connectors for the 6 and 8 pin slots on the GTX 760. I only found 1 white 4 pin which a I believe is the molex. Then under it I found 2 black 4 pins. I don't know what that is. The cable management was so neat and wired up, that I was actually pretty hard at first to find because the cable management was done very neatly with hard plastic laces holding the connectors together. What do i do?
