Inrush: NTC thermistor & bypass relay

Over-current protection on the minor rails is set at normal levels, while the 5VSB rail can deliver lots of power before its corresponding protection kicks in.

The low over-temperature protection, restricted at 75°C, is particularly notable. Normally, a 50°C-rated PSU would have a much higher OTP triggering point.

Finally, the power-good signal is accurate, and the platform is equipped with surge and inrush current protection.
