I'm building a new PC and will be using my PSU from the old PC, but it's still a couple of months before I can start canibalizing it. In the mean time I would like to test out the Aquaero 6xt with the fans and other accessories. I do have a 12V 5A PSU, but it's no 5V on it. Can I use it to power the Aquaero or will the lack of 5V be a problem?
