Changed the last caps near Optocouplers 2x 2.2uF 50V to 3.3uF KYA 50V and lastly the primary cap. Only thing that bothers me is the TNY178 mod I did which has socket now and a small heatsink.

Photo with Finished looks, hope it will last.

Around the TNY chip there are 4 caps, 2X 220uF 35V and 2X 10uF 50V. All junk JUN-FU WG showing horrible reading. I replaced the 220uF ones with ZLH 220uF 35V and the 10uF ones with Nichicon SV 10uF 35V. Changed all the secondary ones too from Capxon/Aishi/JunFu into ->

3.3V - 2X KY 2200uF 10V
5V - KY 2200 10V + KY 1000uF 16V
12V - 2X Rubycon ZLH 1800uF 16V (*no space for more than 10mm. Old were Capxon KF 2200uF 16V)
-12 - Rubycon ZLH 330uF 16V (who uses 1000uF caps here?)
5VSB - Nichicon HV 1500uF 16V + Nichicon PW 1000uF 10V

PG Cap near sitronix...

I have this Corsair VS450 PSU which lies dead and has an exploded TNY chip. Upon removing primary side parts like mosfets, the bulk cap and the bridge rectifier I've found that the primary cap is also a goner. (Photos)
The mosfets and the diode are fine and survived the collapse it seems. The TNY chip is shattered and from the online review/sources it was probably a TNY176~177....
