Should be OK but would be advisable to use a in-line fuse say 1 Amp max.
the min. guess 500mA being better just for peace of mind should anything
go wrong.

The coin mech unit is self-contained and comes with warranty.

Connecting it to th 4-pin 12v molex connectors sounds good. Is an
in-line fuse really need? Say, the coin unit itself can be trusted...
could the PSU itself cause damage?

Do all other PC components have fuses? ie FDDs, fans, LED lamps etc? Is
it a hazard without one? What could happen?
