PSU compatibility for my IIci question.

[geokov]

I would just like to confirm to be sure, can an ASTEC AA16870 PSU be used as a test PSU in my IIci?

Current IIci PSU ASTEC AA 15831 is not working.

Thanks

I have an AA15830 power supply in mine.

What's wrong with your AA15831?

It wasn't working but I recapped it and it's working now. I wanted to test my IIci with a known working supply before I tried my recapped one.

You can use the IIcx one in the IIci yes. Same pinout. Just slightly different ratings on the 12V and -12V lines but not substantial enough to affect testing with it.

These power supplies tend to have a problem with the 5V trickle supply that is used as part of the soft power on these machines.

IIci logicboards also tend to have issues with the startup/shutdown circuit affected by leaking caps.

Thank you for taking the time to help, I did test it in my IIci and it worked fine.
