230V Only of course.
Really? Are there left any ATX PSUs without wide input voltage range? It certainly has PFC, so should work from 100+V as well.
Yes there are, but mostly in the lower price region.
Because you can cheap out on the PFC stage as you need less current to go through that. But most of the 230VAC ONLY units are to be avoided, only a couple are somewhat decent. And the list is rather short.
We are talking about be quiet System Power 9, Xilence Performance A+ und X. And that's about it.
And there are also some Super Flower PSU that are, obviously, 230VAC only. But you can look it up yourself. Because it should hit you like a truck when you see it ^^
With that you can spot a 230VAC PFC pretty easy, if you know what you are looking for.
For example, look at this enormous PFC Coil of another 230VAC Only unit (Cougar STX350W)
So you can use a smaller PFC Coil, lower amperage full Bridge Rectifier, PFC Diode and also PFC MOSFETs...
