Is there value in fixing a PSU?
I understand that unless you possess the right expertise, you shouldn't try it. Let me be explicit—I won’t attempt this (for clear reasons). In fact, I’m just exploring out of curiosity. People say that fixing a PSU isn’t worth it unless you have the proper knowledge. (Unless I’m overlooking something)
If and only if you understand what you're doing and have been trained to do it, repairs can be made. Even most parts a qualified person would need cost less than $20.00, but that's excluding labor expenses. For the regular folks like us who know enough to be risky, new is the best choice.
No. The expense of hiring a professional would exceed the cost of a new one.
If you're familiar with the process and have all the necessary tools, you likely lack the time to spend on repairing a dead PSU.
Most reliable PSUs come with a 10-year warranty, offering free replacement during that period.
Unless your actions were reckless and caused the failure.
In that case, you simply don't know enough to handle it.
After the warranty expires, replacement becomes unavoidable.
In a vintage setup with unusual setups, being able to identify and swap out components would be beneficial. Frequently, power supply issues stem from worn capacitors. For today's more common systems, it's usually more affordable and simpler to just replace the part.
I support fixing things, but a PSU is a component that deserves respect. Still, regardless, before tackling any electronics repair, you must have solid knowledge and skills. It's similar to wondering if it makes sense to patch a bug in the Linux kernel—yes, but only if you really understand what you're doing or Linus Torvalds will send you a long email.
