A mouse killed my power supply unit

[osmany]

Hello, believe it or not, a tiny mouse managed to enter into the power supply unit of my computer through the fan. I found it there (electrocuted when I opened the psu to try to see why it stopped working from night to morning.
After removing the dead mouse, I inspected the psu and at first sight, nothing seems to be burned or burst, even the fuse is Ok.
My question is: What components on the ups may have resulted damaged due to the shortcut caused by the mouse (I found it attached to the area where the power cord is plugged)
Secondly, would you please be so kind as to provide me with a step-by-step guide on how to attempt troubleshooting or repairing this ATX psu with such a singular problem?
Power Supply specs:
CODEGEN switching power supply
ATX2 03(P4)
400 Watts max.
Model:200X1 Made in China

I think it would be better to purchase a new PSU, not repair unsafely the old one. (go for 550Watt this time)

As for the UPS, this should be OK, but this will need testing too - ie without plugging into the computer first.

I would just buy a new one

There are no user serviceable parts in a PSU. Replace it at once.

The capacitors can give you a nasty shock and the chemicals can be toxic.

Yes it should say that on the label too, No servicable parts

Power supplies hold charge in them, even when off.

Do not try to repair the power supply
Put the metal cover back on, mark it with a big cross, and dispose of correctly
