5 signs it might finally be time to upgrade your PSU

The image shows a Straight Power 11 750W power supply unit (PSU) in a close-up shot. The PSU is positioned on a white surface, with the box it came in slightly visible in the background. The foreground is dominated by the PSU's rear panel, showcasing an array of connectors and labels indicating their functions, including motherboard (MB), peripheral (P8) connections, and drive connections. The background is somewhat blurred, but a white surface and the partially visible box indicating that it's a 750W power supply are clearly seen.
As a PC user, you probably already appreciate the crucial role of a power supply unit (PSU). It’s not only responsible for routing the correct voltage to every component inside the PC, but also keeping everything operating at peak performance (and importantly, stability). Without adequate and clean power, your CPU, and GPU can easily encounter issues that you might fail to diagnose at first glance.

Two places many PC sellers compromise on to save costs, are the power supply and the case. So often upgrading your PSU with a quality one, can make a real difference, and you may need to anyway if you want to install one of the newer graphics cards.

Quite frequently stability issues arise from cheap PSUs where they cannot sustain loads nearer their rated limits. Another big plus is many after market PSUs are dead silent.

Another overlooked issue with cheap PSUs, is they typically just have a thick bundle of cables coming out of the PSU, no matter whether you many only be using a few of them. After market PSUs will usually have connectors on their casing (like the featured image on this post), so that you only connect what you need to use, and cut down on the cabling clutter inside the PC case.

Turning An ATX PSU Into A Variable Bench Supply

Black rectangular box with a red power rocker switch in the middle. To the bottom right of it are a number of black twist on covers with the word fuse on them. Below them are red sockets. Top left is a colour display showing 0.00V, 0.00A and 0.00W. It has a round silver twist knob for adjusting. Top right is a USB socket connector showing QC 3.0 and QC 3.0 for the two USB-A sockets. Bottom left is again one fuse cap, and two red and black sockets for accepting banana clip power cables. With them are also two additional red and black connectors for plugging in wires.
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

Bild/Foto
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.

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.

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.
