Delta Source - ADP-30GF
Guys, I have a power supply like this, it is used in a Cisco SG300-28, but it suffered a discharge and the Q2 exploded. I don't think of anything like that.
The IC used is a uc3843b and the FET is a K2544.
Would anyone be able to help?

The hot air didn't work. I did a Reflow on the chips.
I'll keep looking for something in the GPU voltages.Leave a comment:
