If you can't do it with 15 pins max., you aren't doing it right.
You don't have to use all 15 but, I think 15 pins will cover everything.
Even the 24 pin ATX pinout has 14 duplicates. 24-14 = 10
I think we can probably get by with just ONE ground wire... not EIGHT, on the 24 pin ATX connector.
Manufacturers are just lazy. There's at minimum 6 screws that are also ground... holding the motherboard in the case.
There's 5x 5v wires and 4x 3.3v wires... wtf?!? LOL
Even crappy motherboards are 4 layers thick. So you can't even blame it on no room for traces. :/
USB 4.0 has 24 pins also. I can get rid of 6 without even trying. It has 4x ground and 4x Vbus. Pure duplicates, for no reason really.
M<aybe make all connectors like USB 4.0.
12 pins per side for 24 pins total. And you can have two grades... fat and thin.
Same connector, just one for wires carrying greater voltages/amperages whatever.
Use them for everything. Vid cards, power supplies, peripherals, anything.
If you don't need all 24 pins... fine, don't use em.
Hell, you could even use it for the case front panel connector.
No one would be able to get those hookups wrong, ever again.
That's it. Forever more, one connector... fat and thin, same pins.
Make all the cables twisted pair and shielded. Use exterior insulation on all of them.
So ya go to the store and ask for USB fat or thin. Easy.
They'd have to make color coded sets for idiots.
So you don't plug the ATX power supply wire into your speakers, or whatever.
And last but not least.... instead of teaching kids about all this "woke" junk... teach them how to build computers.
Hell, the way the price of wood has gone up... get rid of woodshop and have computer shop instead.
