This fanless PSU delivers almost 877W of power before its over-power protection (OPP) kicks in. That's impressive, to say the least. Over-current protection (OCP) on the minor rails is set normally, given our expectations. Meanwhile, it should probably be set a little lower on the 5VSB rail since ripple gets out of control with 4.2A of current.
The over-temperature protection feature is configured properly, given the lack of a cooling fan. Short-circuit protection is available on every rail, the power-good signal is accurate, and the PSU is protected from voltage spikes and large inrush currents as well.
