SuperMicro PWS-920P-1R
« on: October 27, 2017, 04:23:45 pm »
Hi All

I am trying to resuscitate "dead" power supply from SuperMicoro server. During the visual inspection located evidences of "magic smoke" and after a "quick fix" would like to test it. The problem is I can't find a way of starting it without the server itself. Does anyone have a pinout for it and what should be shorted like in regular PC switching power supplies or there is another way of starting it. Any advice is appreciated. Attaching some pics.

Thanks!

It looks like the fuse failed rather catastrophically. Chances are it will again, unless you replaced other blown components as well...

Agree, but there are no other visible damages and I was going to test it under light load first if it starts at all. The health LED indicator is still amber, but it may mean anything. Very likely I will need to continue the investigation before it switches to green.

Thanks
