Dell Optiplex 7050 Tower ATX Pinout

Does anyone have the pinout for the P1 - 6-pin ATX mother board connection on the Optiplex 7050 midsize tower?  Here is a picture of what I'm looking for.  IMG_3166.jpeg

First off 20 pin ATX is from 1995.

24 PIN eps12V pfc is what modern systems use.

The black wires are ground. White wires are 12V and The green wire is the power on and the grey wire is 12V standby power.

To adapt a power supply OUTSIDE THE case requires an adapter.

its not passive and requires conversion.

Optiplex 3020 9020, Precision T1700, Power Edge T20 also use an 8 pin connector for this.

There is also a guy who made his own adapter from scratch.

This is not actually a passive cable wth connectors.

This ancient post shows the psu outside the case.
