I think it's a circuit breaker reset. I haven't seen one on a PSU ever, and I have built several PCs.

If we knew the make and model of that PSU, we could probably find it in a spec sheet or manual.

What brand and model power supply do you have?

It's simply an On/Off switch, that turns the PSU & PC on & off. They were common, and typical, throughout the 80's, 90's, and 2000's, the last times I built a PC.
I presumed they still were.

So is it like a quick reset button? What advantage does that have over flicking the power switch off and then on again?

That button might be a reset button. So not sure what the reasoning was for the redundancy in putting that there. As I don't recall seeing a reset button before, like that one, on a tower PSU. Unless it's a lock-button that unlocks the action on the toggle switch, so as to prevent the I/O toggle switch from being inadvertently or accidentally switched off.

But the I/O toggle switch, which is what I thought the op was asking about, is an On/Off toggle switch.

No. It just completely cuts power to the PSU thus to the computer. It was mainly used to disconnect from the mains if it was going to be unused for extended periods instead of crawling under the desk to disconnect.I wouldn't use it as a reset switch, it would be like pulling the plug from the wall while it was running.
Basically a safety feature.
