Power Supply Unit Manufacturers

There are many power supply unit manufacturers, but among them, Kuroutoshikou, Corsair, and MSI are the most popular, followed by well-known brands like Thermaltake and DeepCool, which most custom PC users have heard of.

The top three manufacturers account for 55% of the total. Kuroutoshikou is chosen by one in four users, while Corsair and MSI are each selected by about one in six or seven users.

Power Supply Unit Price Range

The main price range for power supply units is under 30,000 yen.

If cost performance is important, a price under 15,000 yen is a good target.

If you want more certifications, features, or cables, the price will usually be around 20,000 to 30,000 yen.

Power Supply Unit Form Factor

The main power supply unit form factors are ATX, SFX, and SFX-L, but ATX is overwhelmingly popular.

Although the graph shows models that support multiple form factors separately, ATX alone accounts for over 95% of the total.

SFX and SFX-L are convenient for compact PC cases, but they make up only about 2% of the total, so they are not very popular.

Power Supply Unit Capacity

When choosing a power supply unit, capacity is important. The most commonly selected capacities are 650W, 750W, 850W, and 1000W, which together account for about 80% of the total.

The graphics card and CPU are the main components that use a lot of power in a custom PC. Deciding on these two first and estimating the required power supply capacity will make it easier to choose a PSU.

There are also guides on how to calculate power supply capacity and a power consumption calculator, so be sure to use them.

Data by Power Supply Unit Specifications and Features

Next, let’s look at the data by specification and feature.

However, when choosing a power supply unit, the main criteria are usually capacity, certification, modular support, and price. Therefore, it is likely that the selected part just happened to have certain features or specifications, rather than being chosen specifically for those features.

In other words, it is difficult to distinguish whether a part was chosen for a specific feature, or if it was just a result of the main selection criteria. Please keep this in mind when reviewing the data.

Power Supply Unit 80PLUS Certification

The 80PLUS certification shows the power conversion efficiency of a PSU. GOLD and BRONZE are the most popular certifications.

These two account for about 85% of the total, and are recommended because they are also affordable.

There are also higher efficiency certifications like PLATINUM and TITANIUM, which can save a little more electricity.

However, the price of the PSU itself increases a lot, so it is not always cost-effective to pursue the highest certification.

Power Supply Unit ETA Certification

ETA certification also shows conversion efficiency, similar to 80PLUS, but it evaluates efficiency in more detail.

GOLD and PLATINUM make up over 90% of the certified units, which seems popular at first glance.

However, only about 30% of all PSUs have ETA certification, and among those, 85% are GOLD or PLATINUM. So naturally, these two have high selection rates.

Compared to the 95% certification rate for 80PLUS, ETA certification is less common. This may be because the cost to obtain ETA certification is high.

When manufacturers decide which models to certify, it makes sense to focus on the mid-range products that sell the most, as this gives the best cost performance.

For mid-range models, GOLD and PLATINUM are the typical certifications, which is likely why these two are so common.

There are fewer BRONZE and SILVER certified units, but for users who prioritize low price over certification, it may be better not to get certified and instead reflect the savings in the price.

Power Supply Unit LAMBDA Certification

LAMBDA certification measures noise in decibels (dB) and evaluates the noise level of the PSU.

STANDARD+, A-, and A are the most popular, making up 75% of the total.

STANDARD+ means a noise level of 35dB or more but less than 40dB, which is a standard level for PC noise.

If quiet operation is important for a custom PC, “A-” (25dB or more, less than 30dB) or “A” (20dB or more, less than 25dB) are good choices.

For details on noise requirements by grade, refer to LAMBDA certification.

Power Supply Unit Modular Support

About 70% of users choose power supply units that support modular cables.

Personally, I expected it to be about half, so this was a bit surprising. It may show that many users want to avoid cable clutter or keep the inside of the case tidy during assembly.

Power Supply Unit Semi-Fanless Feature

The semi-fanless feature stops the fan at low loads, which improves quietness, saves power, and extends fan life.

About 45% of products support semi-fanless, and the selection rate matches this, so this feature may not be a major factor for most users.

Summary: Power Supply Unit Statistics

This article summarized the popularity ranking, price range, manufacturers, and the percentage of selections by different specifications and features of power supply units using graphs.

The most popular power supply unit manufacturers are Kuroutoshikou, Corsair, MSI, Thermaltake, and DeepCool, with most units priced under 20,000 yen.

There are several form factors, but almost all users choose ATX. The most common capacities are 650W, 750W, 850W, and 1000W.

For a mid-range CPU and GPU build, 650W or 750W is usually enough. For high-end builds, 850W or 1000W should be considered.
