I am going to power my first C84 build with my benchtop PS. Can anyone give me an input voltage and the configuration of the header pins on the C84? I think I see Pin1 is + volts, Pin2 is common and Pin3 is - volts. What does the 48P want to see? A jumper from + volts?

Power supply and chassis to come with more amps which comes with more money<g>.

So 30VDC looks good. Still wonder how the voltage gets to the phantom pin and is +30VDC referenced to the common good for that?

Front to back the connections are

1) +30V
2) PGND
3) -30V
4) AGND
5) +48V
6) CGND

Tie all the grounds together at the power supply.

Thanks Tim. As I suspected. You get a separate +48VDC from the PS03 I guess.
