I accidentally connected a 230 VAC to 24 VDC PSU to 400 VAC. After about 5 seconds there was a spark and then the mains circuit breaker tripped. I have added the pictures of how the damage on the PSU looks in the attachments. The PSU's model is PULSE QS10.241.
I don't have much experience in fixing electronics and no PSUs at all. How should I go about fixing this? The varistor clearly needs to be changed and the big capacitor most likely as well. I don't see anything else visibly damaged, could changing just these 2 parts fix the PSU? Are there any tests that can be done before I connected the PSU to power again?
