I recentley just bought one of thoose ultra 500w psu wiht the moddable connectors and what not cause i thouhgt it would be easy to use, but i saw that the dfi sli-dr uses a 24 pin, and thats the board i want to get. Right now i have only 1 6800 gt and plan on going on sli later, am i gonna need a new power supply when i go sli or should i just return this one (still have time for rma) for a 24 ping psu? If i should get a new one which one should i get, link anyhthing. Thanks
