extending power supply cables

Is there any down side to doing this? Im Looking at tripling the lenght of he cables, so this do anything bad to the power supplies. I know cable has some resistance but I'm hoping it's negliable.

Cheers to anyone that can help.

Nope, nothing wrong with that. I've done it several times without any issues. Just remember to do them 1 at a time and follow the colors. This is a double measure of safety so you don't cross any wires and fry something

Pain in the butt clipping/splicing/soldering/heatshrinking each wire, but it's fun and will keep you really busy for quite sometime, lol.

Have fun

Sweet. Cheers buddy.
