PSU Hierarchy 2022 – A Comprehensive Overview


A power supply unit is one of the most crucial components and is considered an important task not only for the PC builder but also for customers. You should purchase a premium power supply unit irrespective of whether you are building a new PC or upgrading an existing system. A PSU is the direct source of energy for the computer and hence the brand should be superior. Otherwise, the internal components will fail to cause serious damage to the system.

If you work with a high-performance CPU or GPU with less PSU, then the overall work will be impacted. The whole process is complicated because you will have to try and match several PC components into a single unit. Nowadays, you have plenty of CPU and GPU combinations and hence there will be a difficulty. In this article, we will examine the ultimate PSU hierarchy 2022, which enables you to select the right choice for your new computer.

Ranking System

The Ranking System hierarchy is based on performance and efficiency. It is to be noted that the 80-plus rating is required when you talk about ultimate PSU. These ratings are a kind of certification created to signify that a power supply is at least 80% efficient at 20%, 50%, and 100% loads. The 6 different certificates such as regular, bronze, silver, gold, platinum, and titanium denote PSU’s efficiency. You should pick a maximum of 2 modes per manufacturer in each tier so that you can arrive at a conclusion during the purchase stage. The PSUs in each tier have been divided into two categories such as multi-rail and single-rail respectively.

The main difference between these two categories is the total number of overcurrent protection circuits. Tech enthusiasts make use of the multi-rail for power supply units with multiple OCP circuits. The single-rail PSUs make use of one OCP circuit. You should note that OCP circuits have no impact on performance. The difference in protection is minimal and manufacturers build single-rail PSUs to offer the best possible protection. The multi-rail PSUs are useful only for PSU/PC enthusiasts.

S Tier

The S Tier is reserved for the enthusiast class. The power supply units in this tier carry an 80+ Gold, Platinum or Titanium rating. However, you should note that PSUs with titanium ratings are not available on the market and are reserved for very high-performance systems. Hence, these PSUs are not required unless you are willing to overclock the premium CPU and GPU. There is a general saying that high-end PSUs could vanish because of the energy efficiency competition between Nvidia, AMD ad Intel. It is to be noted that GPUs such as RTX 2080 and RTX 2090 has an overall power draw of up to 300W. Going forward, we require PSUs with 800W, 900W, and 1000W respectively to accommodate the advanced CPU and FPU specifications. The list of Multi-Rail PSUs is mentioned below

A Tier

The A Tier PSUs fall under the affordable range but will fetch moderate cost. However, the A Tier PSUs won’t overkill even when overclocking the CPU and GPU, unlike S-Tier. The PSUs in this tier are oriented toward tech enthusiasts and it generates excessive power, which is not required for the system. It’s not advisable to buy an A-Tier PSU for a budget PC as it can’t completely leverage the capabilities of the PSU. We recommend additional investment in CPU, GPU, RAM, and storage including SSD instead of opting for a premium PSU, which can’t serve any purpose.

You should opt for PSUs from manufacturers like Thermaltake and Deepcool. The majority of models are rated 80+ Gold in the A-Tier PSU list. The main benefit of A-Tier and S-Tier PSUs is that manufacturers provide extended warranties. The companies like Deepcool, Corsair, and others provide a 10-year warranty for the premium products and hence it’s worth purchasing for your computing requirements.

The Power Supply Unit (PSU) is a crucial hardware component, which is required for the proper functioning of the computer. In the case of a Laptop, you need not have to worry because all the components are concealed below the keyboard. However, you have to allocate sufficient investment for a high-quality PSU if you work with a desktop PC. This is because the internal components like Hard drive, SSD, Motherboard, CPU, Coolers, DVD drive, and much more are powered via the power supply unit. Hence, the PSU should be manufactured by a reputed company because they make use of premium materials, copper wires, and other components.

You should purchase PSUs manufactured by Cooler Master, Deepcool, and Thermaltake because these are credible companies that you can depend upon. Like all technology products, power supply units continue to evolve rapidly and their rankings change constantly. The power supply units are not only reliable but also long-lasting and affordable. The main point to note is that you should select a PSU manufactured by a popular company. A small initial investment will go a long way in protecting the valuable internal components of your PC.
