I have a Corsair HX1000i and it's currently plugged into a 120v circuit.
However, I see the sticker on the power supply states "110 - 240v".
What confuses me though is that older power supplies had a little switch on the back that you'd flick to go from 120v to 240v.
How do I wire this into 240v without that switch? And what's the wiring diagram? Both main legs are 120v? And then the 3rd prong is neutral?
