What make and model of ATX power supply are you using?
I can't think of any logical reason for it not to work.


The A1000 PSU spec specified that the input frequency of the Tick signal, derived from the AC mains should be +/-10% and that it only works on the positive half of the cycle. The european and UK mains frequency is 50Hz +/- 0.5Hz.

My tick circuit used in the adaptor provides a 50Hz/60Hz with an accuracy of +/-0.1Hz at 50/50 duty cycle and works without issue.
