Re: Can you use 2 power adapters on this card?
I have that same PSU and I am planning on using it w/ the gtx280 (when the price comes down and/or my cash flow goes up and assuming nothing better shows up in the mean time). I bought a blank 8pin pcie conn from Performance PCs and I am planning on combining the wires (cut, splice, solder, repeat) from one of the 6-bin pcie with an un-used 4-pin MB conn to supply the 8 pin pcie. I will be, in the process, shortening both cables going to the vid card.
Your solution should work as well I would think. If possible, I would try to use molex conns from seperate PSU output bundles, not two from the same wires, just to limit the current per wire.
