Hi! I have a question regarding sleeving somewhat... but it's more related to electric. I was sleeving my PSU, specifically the 8-pin power for the CPU. I removed the old heatshrink, pulled up the sleeve and marked each cable with masking tape so as to preserve the original order. Long story short, I think I might have swapped two of the 12V's, and maybe two of the grounds (a 12V for another 12V, ground for another ground mind you!) Does it really matter?

Thanks a bunch
