Using a spare DC-DC power supply for point of load power supply?
I have and old Opus 90W sitting here. How can I use this as a point of load type thing to power things like my usb soundcard, xm receiver, crossover, etc..
I have it powered off an old at power supply but since the atx power cable isn't plugged into anything and neither is the mb power on switch, the power supply just keeps flashing 2 flashes every few seconds indicating the motherboard did not power up.
Are there certain pins I can ground or something to make it think it has powered up so I can get power from the atx cable or drive cables?
