So I just got a new graphics card, a HD 4850 X2. Now, I knew that it need a 6 pin and an 8 pin connector, and looking at my PSU specs, I saw that it had a 6 pin and 2 4 pins. I figured I could work with that. Upon obtaining the card, however, I realized much to my dismay that my motherboard is actually using one of those 4-pin connectors. Without buying a new PSU, what is my best course of action here?
