Schematic for DPS-350VB C computer power supply

[Overworked EE student]

Hello, I have an engineering final project that requires me to bypass the rectifier circuit of an AC-DC load by directly connecting that load into the DC supply. My load is a DPS-350VB C computer supply from Delta Electronics INC. I'll need to disassemble that and modify its internal circuitry. The issue is that I can't find the circuit schematic for the DPS-350VB C computer power supply. Does anyone have its schematic?

There non-PFC and PFC power supplies. At least non-PFC supplies (like presented ATX supply) can be powered with 300 - 350 DC, directly through AC input pins. The 110 V feature (enabled by a jumper or switch) is using voltage doubling rectifier and can't work with DC input.
