The PSU Tier List 2024 [Updated With Newer Models]

When shopping for a new PC, PSU is one of the most overlooked components undergoing the most cost cuts. But in reality, you should not skimp on its quality and spend a bit more which will ensure the longevity of your other components.

To help you with this, we have compiled a list of the best-rated PSUs on the market. These are matched according to their efficiency ratings and pricing so that you can choose them depending on your budget.

So, let’s get started.

PSU Tiers Explained

If you have ever laid your eyes on any PSU tier list, the sheer number of units may be overwhelming. I mean, just a single tier has over 20-30 models from different manufacturers. So how do you choose one from them?

That is where the tier system helps you out. The PSUs are divided into groups with similar price points.

Tier A represents the best-in-class PSUs you can buy. You typically get solid components, great efficiency, multiple over-current protection circuits, and silent fans. Some units are a whopping 90 percent efficient in this list. They are the most expensive ones on this list too. So, if you are into overclocking or running an RTX 4090, you should look to get one from this segment.

Tier B represents very good PSUs but without extreme power outputs. Here the units have outputs of 700 – 850 watts. They are efficient, too, with different levels of ratings. You get protection from current and voltage spikes, but some high-end features are missing. For the average user, these units will prove more than adequate.

Tier C contains PSUs that are ideal for entry-level GPUs or integrated graphics. Generally, these are rated up to 550 watts. The efficiency is good for its class but pales down when compared to the higher tiers. Do not consider these units if you are running a beefy system.       

In addition, you also have a separate tier for integrated GPUs and another one for poorly rated PSUs.

The PSU (Power Supply Unit) Tier List for 2023

This PSU tier list originated on a thread in the Linus Tech Tips forum. Then it found life on a different website, where it emerged as a community project.

We have included the entirety of it here. You may not find specific models because they are outdated and out of production. In that case, you are better off purchasing newer models of the same units.

So, here goes the PSU Tier List.

Tier A: Enthusiast Class

ATX 3.0 Compatible

Multi/Single-Rail Switchable

Tier B: Mid-Range

Tier C: Best for Entry Level Builds

Tier D: Best for iGPUs

Tier E: Avoid these

Things to Know When Purchasing a PSU

The first thing you need to know is how much wattage you require for your PSU. One easy way is to go to a PSU calculator and enter the components one by one. The webpage will show you the capacity you would need.

But considering the overall efficiency, choose a PSU with a slightly higher capacity than what you require. This will ensure that you have some headroom when overclocking.

Efficiency is the second thing to consider. There are five tiers: Bronze, Silver, Gold, Platinum, and Titanium. Each tier has a target power draw to meet at certain loads. Titanium units are the most efficient but also are the most expensive. This is due to the good quality of components used on those units. For most users, a Gold-certified unit is adequate.

The last thing is the size of your PSU. This is related directly to the overall size of your PC’s case. Most units are ATX compliant, while some comply with the SFX form factor. Those are typically used with small form factor cases such as the mini or micro ATX.

Frequently Asked Questions

What is the 80% rule of a PSU?

The 80-plus certification is designed to ensure that a power supply is able to provide 80% of the power drawn from the walls to the components at 20%, 50%, and 100% load.

Does PSU wattage matter?

PSU wattage is an indicator of the total output power that a power supply can supply. So you must choose one that can supply what your GPU and CPU would need. If your PSU is unable to provide that, then your PC may not turn on entirely.

Final Words

Now, you can reliably choose a good PSU on your system that will be good to run for a few years. And it won’t be a fire hazard for your other components too.

I hope this piece helps you out on your next PC build. Until next time, it is time to say goodbye.
