Power Supply Sleeving Guide

Get out your expandable sleeving now. I chose a red and gray color scheme, with the sleeving red and the heatshrink gray. Do an eye measure of how much sleeving you’ll need from the inside of the psu to the first molex. Use scissors and cut the sleeving at the required length, then use a lighter to melt the ends of each section of sleeving cut. By melting the ends slightly, the sleeving won’t fray, and it keeps it neat and tidy.

Slide the sleeving on and prepare the next section, using the same method. After you’ve got all the sleeving on one strand of wires, get out the heat shrink and cut off an appropriate sized piece off, and slide it up the strand over the sleeving.

From here, get out the molex’s you put away before, un-tape the pins, and use your paperclip or screwdriver to bend the pins back to their outward positions

On one side of the molex plugs you’ll see the numbers 1,2,3,4. The pins go in accordingly.
• 1 – Yellow (+12v)
• 2 – Black (ground)
• 3 – Black (ground)
• 4 – Red (+5v)

It doesn’t matter if you confuse which black wire goes into 2 or 3, because they’re both grounding.

When you push the wires back into the molex, you should hear a small click. If you don’t hear a click, then you might not have them in all the way – so make sure to check by giving a little tug on the wire. After the molex is back on the wires securely, take out your lighter, heatgun, or other method to heat things up. Position the heat shrink appropriately (what you think looks good) and heat it up.

Voila! You’ve sleeved your main wires.
