DH87MC with i5-4570s. I've been chasing issues with this setup configured as a home server Win 8, using 2xNORCO SS-500 5xSATA III removable drives (6xWD-3T Reds). Finally got things working and noticed that the Power Fail LED on the mobo is blinking. I started with an OCZ-550watt ZT PSU, then, suspecting a power issue a Antec 650watt EA-650 Plat (Turned out to be a BIOS setting.). However both PSUs have the Power Fault LED blinking; one-second on, one-second off. Don't mind the blinking, but unit now also powers-down, and then restarts.
Internet and Intel search have yielded nothing. Hoping someone here might have a suggestion(s).
