I have two weak power supplies (266w & 205w). I have a graphics card that lists 350w as the minimum spec. The 266w supply is actually in the case, and the 205w is surplus. Would it be possible/reasonable to attach the 205w supply to the power jack on the graphics card? Would the card utilize both supplies, or just draw from the case supply? Would this fry the card?

Thanks for your time.

I think, but not certain, that the motherboard power connection needs to be attached to a motherboard for the power supply to function. Meaning you would have to attach both power supplies to the motherboard which is impossible if it has one connection. Someone correct me if I am wrong.

Depends on the power supplies and the graphics card. If the GFX has a slot for 6-pin extra power, then it would be reasonable to connect the power there from the extra PSU to it. And let it draw the 75 W from the installed PSU, and the extra from the other one.

Still, it's not sure that this will work, as the PSUs can be too crappy to be enough.
