Thanks for the answer. Would you mind explaining how the connector is different from a splitter?
Obviously, it is but to non-technical people like me it look a cable coming out from another
.
Cheers!
The cable that came from the PSU is designed to handle both the 8(6+2)-pin and the 6-pin PCIe connectors having a load on them simultaneously. You can definitely get away with using both plugs. I suppose they are technically splitters, the only difference is that the manufacturer intended for both of the plugs on the included cable to provide full power (at spec) simultaneously, and perhaps more, should you obtain your own additional splitters.
However, I'd avoid using splitters until you run out of connectors on the included PCIe cables, and even then, avoid daisychaining multiple splitters. Even though you don't have split 12V rails, you want to be careful to avoid running too great a current through one line of PSU connectors.
