Hi,

I'm wondering whether i should use AWG16 cable for custom sleeved cables instead of AWG18. The PSU is Seasonic Prime Gold 650W and its original cabling is AWG18 cables so going AWG16 would be an "upgrade" (thicker wire, more current, less voltage drop). Tho I'm wondering if maybe i should stay with same AWG18 that Seasonic used and dont try to outsmart them?
 
Solution
Since your wires will be 3ft or less, there will be negligible difference (0.012 ohms for 16 vs 0.019 for 18ga) I wouldn't change. It will just make the cables harder to route.
