Are there any that you need to plug 2 cables to diifferent outlets to supply the power/ or to get 220/240V from a 120v source?

Nope. Only a few rare nuclear reactor PSUs. There isn't much point as it all comes off the same breaker on your household panel anyway. It is simpler to just use one thicker gauge cable a la your clothes drier than doubling up inputs.

Well I was mainly thinking about the efficientcy being better at the 240V rating..?
The only way I can think of getting 240 it to either have the PSU use 2 plugs or or a 240V outlet.

If your house is wired for ~110V, having a PSU with two power inputs will not magically turn it into 220V. It doesn't work like that

If you want 240v AC voltage you'll need to either get a terminal installed into your house. Or get a Variac Transformer.

The efficiency gains on 240v is small so you shouldn't worry about it.

Then why do some server PSU's use multipule plugs to attain 240v from 120v outlets?
(and im not talking about the redundancy plugs/unit)

Efficiency is small but doesnt 240v use half the amps from the wall the 120v does? So with 2-3 PSU's yould be using half the amps?
