I read that non-branded Chinese manufactured power supply units were a false economy as when they go they can spike the main board & take it with it. But trying to find a branded replacement that has a standard backplate but is shorter bodied to fit my micro-ATX case is proving very difficult. I thought they'd all be moving towards miniaturisation?

My local computer shop thought all power supplies could go branded or non-branded, but I thought they had a fail safe against over voltage?

What do you reckon?

Any PSU can fail in such a way as to damage other components. After all, when a PSU fails, it is in a faulty condition - there's no guarantee that over-voltage protection measures are still able to function in the face of every possible fault.

However, cheaply made power supplies are simply more likely to fail, more likely to fail catastrophically, and unlikely to have any protective mechanisms to try to avoid further damage to the system components.

That said, I've had cheap generic PSUs that came fitted to cheap generic cases fail gracefully (eg fail to start up due to bad capacitors), and the system continue to work perfectly with a new generic (eg Codegen) or good secondhand PSU.
