Configuring Opus Power supply with Phoenix AwardBIOS
I am using the following:
ECS K7SEM micro-ATX with Phoenix AwardBIOS
Testing with external DC power supply set at 14VDC (simulating car), drawing 4.26 A. Simulating ignition by connecting the yellow input to the 14VDC input.
I can't get the configuration quite right. The Opus power supply does not boot the system reliably. I've seen everything;
good boot up
fans spinning for a second-.96A draw-another attempt 5 seconds later
fans spinning and drawing .8 A; Computer does not boot
fans spinning and drawing 1.5 A; Computer does not boot
fans spinning and drawing 5.2 A; Computer does not boot
The typical complaint from the Opus power supply is power supply overloaded (3 flashes). All I have in the system is the motherboard, memory, HD, keyboard, mouse, Opus power supply, and touchsceen display running from an AC supply.
Hibernating the system is even more unreliable.
