Question How can I test a PSU?

[chribonn]

I had a homelab computer with a few hard disks no GPU. The computer started crashing and hanging. On the proxmox forums I was told to check memory and PSU.

Memory was OK, and with the PSU I replaced it.

The original PSU I had in the computer was a Corsair RM850e a couple of years old (but out of warranty by maybe a year).

Before chucking it out, is there a test I can perform on it; it hadn't even gathered the "proper amount of" dust on the inside

How can I test

Simplest way would be to decide the level of "tester" you are comfortable with, or a multi-meter which would require a certain level on know how already in place.
The cheapest of those testers can give a very general answer but should not be relied on as the end all, be all on load characteristics.

RM850e out of warranty? Don't think so. RMe is introduced in 2022 and came with a 7 year warranty!
I doubt it's the PSU. What are the full system specs?
What BIOS version is the motherboard running?

Test a PSU with a Multimeter or a PSU tester: specialized tool that plugs into the PSU connectors and displays the output values.

The simple "paper clip" test is useful only to confirm a dead psu.
It says nothing about how the psu operates under load.
You can buy simple psu testers for about $15:

A tester to look at operational characteristics is very expensive. Think some $50k and the knowledge to interpret.

Don't dump the RM850e. Send it to Corsair for a RMA.

For better help, post the make/model details of all of your parts.
