MM, this is awesome. Thanks for doing this.

I looked up one of the components in their latest PSU so I'll give you the data. There are two of these thermistors in it. It's labeled 5D-15.

HERMISTOR NTC 47D-15

Abstract: NTC 5D-15 MF72 Power NTC Thermistor MF72 Power NTC Thermistor. The MF72 series Power NTC Thermistors provide inrush current suppression for sensitive electronics. Connecting a MF72 in series with the power source will limit the current surges typically created at turn on. Once the circuit is energized the resistance of the MF72 will decrease rapidly to a very low value, power consumption can be ignored and there will be no effect on normal operating current.
