First DOA, replacement works great.

PC Repair. The first was dead on arrival. It turned out that some of the DC cables were damaged right where they exit the case. Several tracks shorted. Replacement came quickly, everything works. Perfect for reviving a decades-old PC. But check it before installing!

Pros
