You can solder any black with any black, they're electrically connected in the PSU. There's no reason why you'd want different references for different voltages/rails or anything, rather the opposite actually. Using multiple wires for the same thing like that is just an alternative to using a coarser gauge 😀

Thank you for helping me, kaputnik.

Ideally before soldering them, don't just "glue" them together with solder

Thank you, jakethompson1 !!!

FYI 3.3V wires can be totally ignored. If you are running 2.5", just wire up black (gnd) and red (5V). If you need to run either 2.5" and 3.5" wire up red, and yellow and black wires to theirs wires that's 5V, 12V and ground.

Cheers,

Some psus make all the wires black but if you have other colors. Then black is gnd and which one you use doesn’t matter
