I have a power supply unit (PSU) from a computer where the motherboard possibly shorted out. I'm thinking it might have been due to electrostatic discharge, but I'm not entirely sure. What are the best ways to check if the PSU itself is faulty? Also, is it safe to use it in a different computer I'm building?

You can start with a simple paper clip test. Just jumble the wires a bit and see if the PSU powers on and stays running. It's not a complete test, but it can help you rule out some issues without special gear.
For a basic check, you can grab a PSU tester for around $10. They’re user-friendly and can give you some insights on whether your PSU is working well enough.
To be absolutely certain about a PSU's condition, you’d typically need access to really expensive testing equipment, like what you'd find in a professional lab. If your PSU is older or you notice it’s having issues, replacement is probably the safest route. How old is yours anyway?
While pro testing equipment can cost a lot, there are enough affordable testers on platforms like Amazon that can give you a general idea of the PSU’s health. Just keep in mind they're not as comprehensive.
