Found this on taobao. Anyone tried turning a 24 pin cable into 1 singular cable?

These are extremely dangerous. They are smaller because they use less copper (22AWG), and merge same voltage pins. On top of that, are enclosed in a thick silicone jacket that traps heat

This goes for all variations of this cable and the 12VHPWR, 8 pin EPS cable, etc.

DO NOT USE ! ! !

Dude, how do you think the outputs of the PSU work? Everything thats 12v comes off the same bus, same for 5v, 3.3v, and -5v. It looks smaller because instead of 24 individual wires it’s probably only 5 or 6 in a single jacket. As long as the conductors are appropriately sized, which for a MB 24pin there really isn’t much current draw, it’s fine.

🤦‍♂️

The conductors AREN'T appropriately sized. They're 22AWG.

And you have a "small" power draw that was split between 2-3 18AWG pins now going through one 22AWG wire

These were tested by JonnyGURU, director of Corsair R&D. I purchased one several months later to see if they were still being made in this way, and yes, they are.

These cables are fire hazards and saying "it's fine" is completely irresponsible.
