Every GPU I've ever had has come with a big message on card roughly saying 'DO NOT USE MOLEX TO PCI ADAPTORS!'.Most cards come with the plugs that go from the card into the molex nowadays. DDR3 is dirt cheap but not worth it in your case. I'd buy a new game or two

Never explains why, though; I'm guessing it can't provide enough current compared to PCI.
My 580 came with 2 adapters (6 and 8), my 465 came with 1, my 280s came with 2 a piece, ect. The adapters are 1 6 or 8 pin to dual 4pin molex. It is drawing current from 2 different connectors for a single connector. On a single or dual rail PSU it would be the same as the 12v source is the same.I've never had a GPU that comes with the adaptor, either.
Isn't Molex 4-pin? If so then they're not simply the same thing, since PCI-E is 6-pin. I'm guessing there's an issue there that Molex can't draw enough current to equivalently match the maximum draw of the PCI-E connector, but that would still be fine for lower-end GPUs.
