You would have a momentary switch, if you have that type of connection to your PSU.

I use a Compaq computer here, and there's a momentary switch on it. I haven't opened it up (yet!) but I'm sure I'd find that it is connected to some little circuit board, either inside or outside the PSU, that activates a relay.

I believe that the PSU we buy never come with that option though. As far as I know, they all have those 4 wires: white, black, brown and blue. The toggle switch links those to turn on the PSU.
