Hey! I'm about to make my own power cables and sleeve them in my PC. My Corsair RM 850 Watt has really stiff ribbon cables and don't bend very well. I'm looking on FrozenCPU where I get all my watercooling parts and I see 18AWG, 24 AWG etc and I don't know which to use for my 8 PIN CPU, 24 PIN, 8 PIN PCI etc. Does the size of the cable matter? Also! which size sleeving / heat shrink for doing it individually?
Making my own cables, does size matter?

All primary power cables should be done in at least 18AWG wiring, PSU manufacturers occasionally use 16AWG for CPU and PCI-e connectors due to the high current those power lines will see. I would do at 16 AWG for PCI-e cables, 18 AWG for the 8 pin CPU connector, probably 20 for the 24 pin connector since it doesn't provide a ton of power. I wouldn't go below 20 gauge wire for any cables. 24 gauge is basically signal wire with a resistance per foot that is 4x higher than 18 gauge wiring.
