Maybe I should also get a spare fuse. If the fuse markings are
indistinct, what's the typical fuse value for a 250W ATX PSU? (The
actual PSU model is FSP250-60GTV.)

I wouldn't worry about replacing the fuse. It's soldered in because
the most likely reason for _its_ failure would be a component failure
in the HT module (rectifier, HT smoothing capacitor(s) or switching
transistor(s)) which would require the use of a soldering iron anyway
in the event of any attempts at repairing the fault.

The safety fuse (for that is what it is) is fitted simply to prevent
catastrophic HT component failure becoming a fire hazard. It's not
there to protect components in the HT module.
