I saw this picture while looking at overclocking guides and I wondered if I may have my power setup incorrectly. My GPU is currently connected exactly like the don’t do this diagram.
A well built power supply will have a current limit on the connector to prevent the cable melting problem, but that means if you have a card that needs 200w, but only power it via 1 connector you are going to run into problems
12hpwr/6+6 will do 600 watts using a lot less copper than what you’ll find in 4 8 pin pcie cables.
The ATX standard allows for a 5% voltage drop. This shitty 2.1 star rated extension cable uses 18 gauge wire which is typically the worst you’ll see in a cable. Using this calculator 30 amps on an 18 gauge 3 foot cable leaves you with 0.1v of drop which is within spec. And there’s 3 +12v wires in every 8 pin cable. You’ll be fine.
