*shamefully responds to own post*

Just checked the pinouts and the Ultra 5/10 use the older version of ATX which is NOT pin compatible with the new versions! Arghhh!

The Ultra 5 pinouts are here (warning 5mb PDF) on page 218 :-

/PS_ON is on a different pin and there are some changes to the 3 and 12 volt pins.

Hmmm back to the shop for an ATX v1 PS I guess.

Best regards
