Turning An ATX PSU Into A Variable Bench Supply
Bench power supplies can sometimes be frustratingly expensive and also kind of limited. If you’re enterprising and creative, though, you can create your own bench supply with tons of features, and it doesn’t have to break the bank either.
ATX power supplies work as a great basis for a bench power supply. They have 12 volt, 3.3 volt, and 5 volt rails, and they can supply a ton of current for whatever you might need.
It is usually true that many devices get more fully unlocked regarding features, when open source firmware is applied to them, for example, true for most network routers. This project likewise does unlock some additional functions for an ATX power supply unit.
One caveat here, of course, is you’d be working with voltages so you’d want to be very careful and ensure too that fuses are correctly applied. There is also quite a debate in the comments about whether this is a good idea or not, but that said, I had actually bought an ATX adaptor plug a while ago for a computer power supply to supply 12V for my radios.

How to Test Your Computer’s PSU With a Normal Multimeter
If you have a digital multimeter on hand, it’s pretty straightforward to test your PSU and rule out power gremlins as the source of your computer problems. Standalone PSU testers are great, and we always have one on hand to get quick results. They can even give you useful values like the Power Good (PG) value that shows you how quickly your PSU comes up to full power—that’s something a multimeter can’t do.
But lots of people have digital multimeters on hand already and don’t have a PSU tester lying around. So while it’s nice to have a PSU tester for those little extra features like the PG value, you can get almost all the same data with a more hands-on approach using a multimeter.
These tests will work fine for the start-up and idle voltages, but won’t be testing the PSU under high load (which is only applicable really when gaming or rendering video files, and the PC fails during those types of activities). I’d also do the inverse of these tests to test all the ground wires are good, i.e. put the red probe in one of the working positive voltage pins, and then use the black probe to test all the ground pins.

These are the best power supply units you can buy for your PC in 2022
The Power Supply Unit (PSU) is a critical piece of any desktop. It plays an extremely important role in supplying power to your entire system. Yet, power supplies are often overlooked and aren’t discussed as frequently as some of the other star components like the processor or the graphics card. The power supply unit also determines your system’s reliability, and it saves the parts in case something goes wrong. It’s safe to say if you’re not buying the best power supply, then you’re essentially putting your expensive PC parts at risk.
A PSU should probably easily last twice as long as two CPU replacements, so it is probably worth spending some extra money on. I can also see why Corsair is rated so well, due to its modular cable design and also the very long warranties.

Yes, many bargain shop-sold computers come with woefully underpowered and cheaper PSUs as it's a component that most buyers don't look at. Better PSUs allow more devices to be added to your computer, frequently run more efficiently when less power is needed, and improve stability.
