Would "ANYTHING" power up with a good psu? RMA'd the psu days ago for a brand new unit.. have LED lights on the mobo but wont even spin anything. No onbard grahics, but have 2 250gtx cards. Im at my wits end. Ive tried pretty much everything after getting the new psu. I don't have the parts to swap out anything however, I usually sell or gift my old systems when rebuilding.

Thnx in advance.
