So I've gotten a EPIA M for christmas, and I'm drafting out a case for it, and I've again come to thinking about using both a DC-DC PSU and a AC-DC psu, so I could ditch the inverter in the car, and still have it usable indoors without having to disassemble the case and put a ac-dc psu on it. My question is this, do I need to switch (spdt) all the wires so that only the powered psu is connected to any given device (motherboard, dvd, hdd), or could I connect them both without the switches and use diodes to impeede the flow of power from the powered psu to the unpowered? Or could I simply connect two psus together sans switches or diodes and have it work? Only one psu would be powered at any given time. And if using diodes would work, what do i need in a diode? (ratings, etc, im unfamaliar with them).
No announcement yet.
AC-DC and DC-DC PSU's together?
