Pin layout question; and any way of producing that PSU for others?

Seen the additional pics and your writeup on comparisons & improvements is useful.

I see P24's purple wire is ignored - only power lines (3, 5, 12 & -12) are connected. -5V is ignored. Actually based on your pin descriptions, you have implemented a P20 connector which should work. ATX 2.x P24 layout:



There's 100% match after renumbering pins 13-24 to 11-20 in above diagram: pins 1,2,11: +3.3 V; pins 4,6,8,19,20: +5 V; pin 10: +12 V; pin 12: -12V; pins 3,5,7,13,15,16,17: ground. Here's P20 layout:



How is it that you don't need a power up sequence? Pin 8?

I think one has to settle with an external PSU - perhaps its better. I would prefer the unit with 2 AC inlets (1 for P20 another for the rest including P4). Can one have this design produced in limited numbers?
