Power supply repair attempt on an i7-2600 Dell Optiplex 990 dumpster PC.
An update on previous dumpster PC's.
And the bunker to the rescue.
A couple of things, since you probably don't read Youtube Comments that much:
1. The Formfactor is called TFX, so you could replace it with a "named brand" TFX PSU form like FSP.
2. The Foam is probably Anti Insect foam, that prevents Insects from creeping under the PCB, commiting Suicide and killing the PSU in the process.
3. The Processors aren't that great...
I7-3770 is Ivy Bridge, that one was replaced in 2012 or 2013 by Haswell. the i7-2k and 3k units use the same socket by the way, so you could change them however you want, if you want to.
Anyway, we are talking about something like 6-10 Year old Computers.
The sad thing is that you can use them even today and use it for gaming without any problems. The newest ones aren't that much better (well, at least the 4 core ones)...
