Whenever we plug anything up we cannot get power. We have tested the power supply and get fans and CD drive to work when it is not plugged into the mobo. However, once plugged in we get nothing. We returned the mobo thinking it was defective, but now the second mobo is having the same issue. We have double checked all installation on the mobo and it is done correctly. Is there some sort of compatibility issue with PSU? I've been looking around the internet and have not yet found any such case.
Any insight would be appreciated and thank you in advance,
Matt
