After adding a GPU block to the watercooling loop, the PC now won't turn on with the pump connected. We're using an Aquastream 12V model. Disconnecting the pump (molex) will make the computer boot just fine. Here's where the fun starts. If the pump is connected AFTER the PC has already booted it will run and work just fine. It will also work fine if it's connected to any external PSU using the green and black wire trick. Just not with the PSU that's currently in use. A Corsair CX650M. Does anybody here have any ideas?
