Seasonic's over-power protection is set high. Normally it should be configured to trip at around 120%. Over-current protection at 5V and 3.3V is set at normal levels, whereas it's quite high at 5VSB.

Finally, we observe short circuit protection on every rail, the power-good signal is accurate, and surge/inrush current protection are accounted for.
