Boy are you lucky!
I'm just trying to repair my semi-dead e-pc 40 (turns off after a random
amount of minutes), so I was doing some Google Groups search and am basically
able to describe this by accident.

The pinout is actually described on the specs plate of the PSU.
(nice!! I wish every PSU had that...)

It is:

5 6 7 8
o o o o
* o o *
1 2 3 4
/^\ (MARKER!)

The marker semi-circle on the PSU's figure unmistakenly indicates that it
describes the pinout as seen when looking AT the very connector cable pins
that are supposed to be plugged into the PC, i.e. the order is (just to
make sure):
your eyes - connector pins - cable to PSU - PSU.
(the marker can be seen on the connector, and the pinout really cannot be
showing the opposing side, since then the marker would be on the
opposite side)

Now the pinout:

1 - plastic-filled
2 - GROUND
3 - GROUND
4 - plastic-filled
5 - +19V
6 - PGOOD
7 - SHIELD
8 - +12V

BTW, does anyone know why my e-pc 40 turns off randomly?
It doesn't seem to be the CPU cooler, since I just completely remade that one,
so it may be some power supply issue, such as bad capacitors or broken
voltage regulators. But I'm currently taking a walk in the dark on that one...

HTH,
