Switched-mode supplies wear out in predictable places, mainly capacitors, switching transistors and fans, and almost all of them can be repaired and load-tested.

FAQ

For standard supplies it depends on availability and price; for machine-specific, discontinued or high-power supplies, repair is usually the practical route because an exact replacement may not exist.
