im sleevin my psu and i cant get the 4 squre pin connecter off...its to connect to the mobo as well...how can i get it off....i dont think i can use a molex tool....or can i...?

Well if you're using 1/4" sleeving all you have to do is wrap a little tape around the 12v connector so that the clip doesn't catch the sleeving and it should just slip right over. Also Don't forget to torch the end of the sleeving before you do it or else it will fray badly when forcing it over the conector.

well its hard to get it over..cause its square..and it is 1.4 inch sleeve..if only i could get the conecter off...

Just get some electrical tape and tighten upthe molex pins and wires tightly and wrapped it tightly with the tape. I must emphasize on making it tight. The tighter you make the easier the heatshrink will go in.

Good luck!
