When building a computer, the power supply unit is one of the essential parts to consider (PSU). It gives power to everything else in the system, so choosing a high-quality unit to meet your power needs and keep your system running well is essential. However, with so many options available, it can be challenging to make the right choice. Several organisations have created PSU Tier List to help users make informed decisions when selecting a power supply. These lists rank power supplies based on their quality, efficiency, and reliability, allowing users to create a more informed decision when selecting a power supply.
One way to make choosing a power supply for a PC easier is to know what the different PSUs offer. Our PSU tier system groups by how well they work, their features, and how much they cost, so it’s important to know what you want before you buy.
To save time and stay safe from all issues caused by power supplies, you should get PSU from a high-end Tier A list. But a Tier B, mid-range PSU is an excellent choice if you want a high-quality PSU but don’t want to spend as much. The perfect combination of CPU and GPU is also mandatory with the right PSU. To help you with your decision, we have built a bottleneck calculator. Now that you’ve chosen the right CPU and GPU, you can use the SSD Tier List to select the right SSD for your build.

What are the main differences between Tier A, B, and C PSUs?
Tier A: The Apex of Power
Tier A represents the crème de la crème. These PSUs are constructed with top-tier components such as Japanese capacitors, MOSFETs, and transformers, which all contribute to their superior build quality. The result?
1. Stellar Efficiency: Energy waste is significantly reduced leading to cooler operation.
2. Unmatched Stability: They provide consistent power even under high-demand workloads.
3. Whisper-Quiet Operation: Their high-quality components create minimal noise.
4. High Power Capacity: Often exceeding 1000W, they’re perfect for PCs that require a lot of power like those with overclocked CPUs and multiple GPUs.
5. Advanced Features: Expect modular cables for neat case interiors, digital monitoring, and even individually sleeved cables for aesthetic appeal.
However, this level of performance comes with a higher price tag.
Tier B: The Ideal Balance
If you’re looking for a balance between performance and value, Tier B PSUs are your best bet. They may not be as luxurious as Tier A but they still offer reliable operation thanks to their high-quality components.
1. Adequate Wattage: Ranging from 550W to 850W — suitable for most mid-range and some high-end gaming PCs.
2. Decent Feature Set: They often come with modular cables and basic monitoring options.
All these factors make Tier B PSUs a popular choice among users due to their blend of performance, features, and affordability.
Tier C: The Economical Choice
For those on a budget who don’t require cutting-edge technology in their PSUs, there’s Tier C. These units prioritize cost-effectiveness over advanced features.
1. Lower-Quality Components: May use less efficient parts and simpler designs.
2. Limited Wattage Range: Usually between 450W-550W — ideal for basic office PCs or low-tier gaming setups.
3. Minimal Features: They often lack modular cables and advanced monitoring options.
While Tier C PSUs are the most affordable, bear in mind that they may have lower efficiency and stability.
Should I choose a multi/single-rail switchable, multi-rail, or single-rail PSU?
A switchable multi/single-rail PSU lets you choose between using more than one 12V rail or just one. If you want more control over how power flows through your system, this feature can help. Comparatively, multi-rail PSUs have more than one 12V rail; as a result, it protects against overloading. Single-rail power supplies only have one 12V rail, which makes them more efficient and easier to work with.
You should always choose a switchable multi/single-rail PSU because it allows you to choose between multiple and single rails, depending on your needs. That’s why It also gives you more protection against overloading. But it’s important to note that single-rail PSUs are also a good choice for distributing power in a simple and easy way—ultimately, choosing which of these options will depend on your needs and preferences.
How do I know if a PSU fits my system’s power requirements correctly?
The first step in determining which PSU is best for your system is determining how much power it needs. You can do this by using a power supply calculator online or by adding up how much power each part of your system needs. Once you have a rough idea of how much power your system needs, you can compare that to how much power the PSU you are considering putting out.
Another important thing to think about is the PSU’s efficiency rating. The PSU is better at turning AC power into DC power if it has a higher efficiency rating. This can help you save money on energy costs and keep your system running cooler.
You should think about how many connectors and cables the PSU has. Ensure the PSU has enough connectors to support all the parts in your system and that the cables are the right length.
What’s a good rating for a PSU?
Most mid-range to high-range systems today will be rocking an 80 Plus Gold-rated power supply, as they are incredibly reliable and relatively low cost. These PSUs might even be more popular than Bronze-rated ones! So, consider going for a Gold-rated PSU to keep your system running smoothly.
Is there such a thing as a truly rated PSU?
Well, that’s a tricky one. While certifications like 80 Plus attest to a PSU meeting certain requirements, there’s no absolute proof that a PSU is accurately rated. So, in short, the answer is no.
I think it’s always best to go for a bit more expensive and high-end PSUs (if you have the budget) because they work better and have more features. They also last longer, which saves you money in the long run. Also, they have better safety features, which are very important to protect your other expensive parts.
