Trying to complete a new build using Core X71 case with MSI X470 MB. Plugged in and case button/switch turns on the system, but it won’t turn it off. I have to use the PSupply switch to power down. Is this normal? if not, what leads did I hook up wrong. The instructions are not really clear from MSI nor Thermaltake. At least not to me. It’s as if they expect me to have some idea what I’m doing. Ha ha ha Not even. Aloha
