Over-power protection is set quite high given this PSU's thermal output under high loads. Thankfully, over-temperature protection kicks in to protect the SPR-0850F-R if its fan can't keep up.

OCP on the minor rails is set high, especially at 3.3V, while at 5VSB it's set at a normal level.

There is short-circuit protection on all of the rails, and the power-good signal is accurate (though the hold-up time is pretty low).
