Ok, so I've got a cheapie grey box PSU with horrible multi-coloured cables. I'm thinking of individually sleeving the cables, but as it's a non-modular PSU I cant buy the cables and replace them.. Now, my thinking is that as the cabling in the PC will be hidden apart from where it connects to the Mobo and the fan cables I could cut the cables in half.. Slip on some sleeving and then solder & heatshrink the wires back together before heatshrinking the sleeving in place. Is this doable? Or would the power be too much for just re-soldering the wires back together? I know that I could spend hours taking off each pin and doing it that way, but I wont be able to sleeve all the cable (non-modular) and as it's mostly going to be hidden.. I dont see it as cheating too much! So is it a good idea? And more to the point, is it safe?
