So I've built a new rig after five or six years and I decided to go water cooling. I bought a jumper so I could purge the air and leak test before firing everything up. Well, I had some issues at first and I thought it was just cabling. But I eventually got the pump running by itself with just the power supply. I ended up buying a set of Corsair AX850 individually sleeved cables because I didn't feel like sleeving a whole set myself. I changed out the corsair ends for the seasonic ones and triple checked my wiring. Now, with everything hooked up, when I hit the power button I just hear a click from the PSU and the fan on it spins for a brief second, but nothing else turns on. I do have a green light on the motherboard. And i tried turning just the pump on with the jumper again without everything else, and it just clicks. Any ideas? The wiring is correct, my only thought is that there may be some resistance difference between the corsair cables and the seaonic ones. The seasonic ones are toast at this point, so I can switch them back.
