The model is DELTA GPS 300 AP. This SMPS has two ic one is 16 pin DWA105 N161 907 J03A3
and. Another is 8 pin UC3843BN. CPCG 0904G..

And it has no bulged caps. I am attaching image.
The UC384bn is a small 14 pin smps chip usually like this circuit

Beware of High Dc voltages of around 400V, the DWA105 is the main smps chip with the over sense, no datasheet sorry, is it an ASUS psu?
