SIPSurge: MOV Inrush: NTC thermistor & bypass relay

Antec's 5VSB rail has its OCP triggering point set too high. However, this rail still keeps its load regulation and ripple suppression under control.

The PSU shuts down at 1041W, which is quite a lot for a 750W unit. Over-temperature protection is set conservatively, too. We do observe short-circuit protection on all rails, as we'd expect from a modern PSU.

Finally, Seasonic's platform is equipped with an MOV and an NTC thermistor, with the latter supported by a bypass relay.
