Sleeving/Heatshrink Question

Ok, I finally decided to get 3/8" blue UV reactive sleeving for my PSU cables. But the question is, for the heatshrink, am I suppsoed to buy 3/8" or the 1/2" heatshrink? I think it is supposed to be the 1/2", then it shrinks. Right? I'd also like any other opinions on this whole thing :).
 
You'll only use the 1/2 inch when you're sleeving the ATX cable or anything of simuler size.

You might want to read what you just posted, but what he's saying is that the ATX wires are thick, not many other cables coming out of the PSU are that thick.
(not actually thick, but its a bunch of wires all going to the same connector, 1 wire is thin, 10+ wires together is thick)
Also you may have trouble getting the heatshrink over the connectors. Thats the other reason for the 1/2" heat shrink
 
Well, the ATX wires came sleeved, so I'm ok there. And I will be removing the molex connectors for this. I found a good guide, so now I know I should be using 1/4" sleeving, but I still don't know what shrink goes with the sleeving??? Do I use 3/8" shrink and then it tightens up? Or 1/4"? With 1/4" will it be hard to stretch over 1/4" sleeving since they are same diameter? Then will it shrink extra tight?
 
Rule of thumb is that heatshrink will shrink down to about half it's original size.

I'd go with the smallest heatshrink I can comfortably fit over the sleeving, that way when it shrinks down, it will be tight, and hold in place.

IIRC I used 9mm heatshrink for most of my power leads, so that would translate to 3/8
