110 VDC Input on a regular ATX PSU
I talked to one of the guys who is working on the power supply designs that we do at the uni and he pointed me into a direction that I haven't read about before. He said that I could just input 110 VDC (* sqrt(2)) into my regular ATX PSU and it would work unless it has PFC. He said that most ATX PSUs use a bridge rectifier setup to convert AC to DC. That would be a pretty straight foward and dirty solution to get a inverter-less setup with a semi-good efficiency.
Is it really that simple or did we overlook something?
Thanks in advance!
