I got bit by the short in syscooling's wiring. Now I can not power 1/4 boards. If I apply power to it, my PSU goes into protection mode. So I have to run this C1 with 1 board unplugged.

Syscooling is using way too cheap electrical parts... I wish I would have see this thread before I started. Can someone post something in big red bold at the top of the OP with a warning to either not use the syscooling wiring harness or check it first?
