I know most would say that it probably does not matter But I just think it would be more efficient to use the 2 single 6+2 pin...let me know if I am wrong please
If you're expecting a heavy current draw by the graphics card then using two individual power cables is preferred because the voltage drop at the graphics card's PCI-E connectors will be halved.
Using Y cables is generally a bad idea, as you get voltage loss in the extra set of joints, plus insufficient cables for the GPU usually means that the PSU isn't powerful enough.
I don't think i typed that correct. I was pretty sure that it is OK to use the either one. Why would some brands not even send a Single 6+2 connector and just send the 6+2 pin(x2) connector
Oh. You mean two plugs on one PSU cable. I thought you meant aftermarket double adapters.
No problem; they will have made sure the cable is thick enough to handle the current.
Oh yeah..Not an issue with the cables/connectors. I have been sitting on a Corsiar AX760 for about 2 months now. Finally got my Case and I am taking sweet old time putting everything in. Right now I am using a CX750M and I think There is a few cables missing from it. I am using the PCI-E 6+2 pin(x2) cable with my GPU no issues with that.. The AX760 PCI-E 6+2 is as thick as the 6+2(x2)..My thoughts are More cable is more power...in any thing really. gaming mouse cable, Dual Link DVI Cable...i don't know, seems right
