My Silverstone PSU no power to motherboard. Is it worth repairing?

If not wat can do with it? don't want it to end up in land-fill

Checked for blown fuse?

I had problem with Silverstone cable before. Psu was working normal

Its never worth 'repairing' a PSU. Check for cables and fuses, perhaps your mobo is the culprit? If confirmed PSU dead, just replace it and send the RIP one to a ewaste disposer/recycler.

Usually PSU has a very long warranty period, is it out of coverage?

Any contact details for ewaste disposer? Or anyone wants it to try to repair?

If in KL, usually Alam Flora has collection drop offs for ewaste.
