Hello!
I bought a Thermaltake ToughPower GF A3 Gold 1050w PSU. I have two motherboard connectors—one with an empty pin hole and the other with two empty ones. ChatGPT advised me to use the one that came with my PSU, but I’m unsure which is which. Does it really matter which cable I choose? The PSU manual doesn’t mention anything about this, so I’m a bit worried.

The correct one would be either all black, or all white wires with black connectors, depending on which color PSU you bought. It could matter a lot as there is no standard way to wire the PSU side, and the monochromatic wire colors are no help. But if you didn't mix up the other cables, the small markings on the wires of those Molex and SATA and PCIe cables should match the ones on the 24-pin
To be sure, you could jumper the end of the plugged-in cable using the paperclip test then check each pin on the 24-pin of the running PSU with a multimeter for the correct voltage:
Or you could contact Thermaltake and ask them which is the right one.
