Yes, I agree that the pinouts in those diagrams are different, it's just that I keep finding information such as this

It should be OK if the PSU has a sufficiently generous +12V supply. Likewise a
PSU with an ATX2 connector will NOT be OK if the +12V isn't up to spec.
An ATX connector has the same pinout as the 20 pins at one end of the ATX2
connector, and they are intended to be compatible.
As always, a picture is worth a thousand words. Those diagrams that have worried you show the connector pin numbers in one long column, whereas the actual physical connectors are not like that.
If you look at this picture, you will see that the ATX and ATX-2 connectors have the pins arranged in two columns. They are numbered from the top left corner in these diagrams, pin 1 being square to ensure that the connector can only go one way.
Now, on the ATX power connector the left hand column runs from 1 to 10, and the right hand column runs from 11 to 20. On the ATX-2 connector, they run from 1 to 12 and 13 to 24.
So, pin 11 on an ATX connector corresponds to pin 13 on an ATX-2 connector. If you compare the left hand connector with the top 20 pins on the right hand one, you will see that the voltages match. COM and GROUND mean the same thing.
imanidiot, depends what CPU & GFX card he is using, whether the PSU will be OK. Whatever, it won't damage the board.
