I just want to ask what other wire size I can use which is smaller than what PSU are using. I'm kinda in an area where cable sleeve supplies are impossible to find and shipping one is quite expensive for a sleeve so i have to be more creative. I found a possible sleeving and it kinda fits through the wires but I get to the point where it I can no longer slide a sleeve to the wire and something smaller than the PSU wire would do the trick. I have zero knowledge about wires and don't want to risk using smaller and thinner wires not knowing if it will hold the power going through the system.
