ATX connector to STe power diagram

[dma]

Hello there, i have not found any clear concise information on this, so i am asking:
Could someone provide/explain the connections from an ATX connector to STe power connector + power switch ?

Sorry if this is utterly obvious for electronics experts but as this is a sensible element, i would appreciate some clear directions, "pre-checked" if you will.

Thanks in advance.

Switch is PS-ON (green) to ground (black). Ground is black, +12V is yellow (blue on ST), and +5V is red (same as on ST). ST power connector is (from left/cartridge port to right/floppy drive): 1, 2: +5V, 3, 4, 5: GND, 6: +12V (formally the pin numbering is reversed).

@tzok : OK many thanks for the precise answer.

So, according to these two schemas:

The following diagram would work, isn't it?

Anyone able to confirm me that this montage would work?

According to the pinout on the site you linked all seems to be right.

EDIT: (Your switch should be a momentary one) Not true apperently. I was wrong. Sorry about that

Seems ok, switch needs to be a toggle switch, not a momentary one.

Yup, I changed my post. Usually you used a latching momantary switch on old PC cases. Same as a toggle switch.

Many thanks for your attention and review guys, i can now go for it and revive the STe.
