Okay, I'm planning on getting a opty 144, biostar TForce mATX, and, eventually, a 7800GT. Only problem is, after the opty and biostar, I have almost no money. Will a 300W [email protected] even run the computer? If it can, then I can hold off the PSU until I have money and can get a good one. But I'm guessing my PSU can't handle it, so I'm going to need the cheapest possible PSU there is, but will give me enough power to OC and eventually hold up a 7800GT as well.
