PC's wire gauge?

[Greboth]

Hi all

We don't have a psu section so have to put this here. Hoping some of the gurus round here can help, I will be braiding all my cable inside my pc and as I will be using white braid I will probably have to replace the coloured wires with white ones but I can't find what gauge the wires are.

So far I have found some info on it but the dates are old so correct me if it is out of date and wrong.

24 pin - 18 AWG
Fan cable - 24 AWG
Mobo connectors - 26 AWG (assume this to be front panel switches, audio, usb etc)

I assume that molex, sata power, 8 pin mobo, and gpu cables are 18 awg too?

Any and all help on this appreciated

It'll vary from psu to psu and wire to wire. Just looking at the 24 pin you'll probably find 2 or 3 different sizes. Still, it'd probably be fine to go with 18 awg for most psu wiring though as lead lengths are short and voltage drop won't be much of a factor.

Most of the wiring will have it's size stamped or printed in the cable anyway, along with it's ul number so you can simply note that and use similar/identical spec wiring.

I am cheating slightly with the cable and braiding extensions for the most part. I feel stupid now though, never thought to actually check the wires themselves. Just checked what I can, the 24 and 8 pin extensions I have here to braid are all 18awg and all the fan cables and front panel I can see are 26. If every other wire I want to braid is labelled this job just got a lot easier, thanks tealc.

According to Hardware Secrets, 18 AWG is the standard for the power supply wires, and some beefier PSUs use 16 AWG.
