Brief me on a couple things...

[buffbiff21]

Like the title says, I need a little knowledge

I am going to sleeve my 850w Zeus. I have sleeved many things before - I am familiar with the Chinese-handcuff style material and with using a heat gun for the shrink. However, I have never sleeved a PSU. So, I need something to remove the wires from the 6pin PCI cables, the 24 pin main cable, and such.

Would this be my remedy?

If so, nothing problematic about that, but I want to know a couple things:

My questions:

A. First of all, will painting some of the wires white/gray void my warranty?

B. What do the wire colors represent?
From what I have seen, I can guess that

Yellow = +12v rail
Red = +5v rail
Black = ground

Is this correct? I want to SPRAYPAINT the yellow and red wires white and gray respectively. (before sleeving them) And yes, I will keep track of which ones go where.

Thanks in advance
