Seasonic 80 PLUS® Certification

Learn what 80 PLUS® certification means in terms of your PC efficiency. In this article, we explain the main differences between certification levels and how they impact your PC’s long-term reliability and smooth performance.

What is the

80 PLUS® certification for power supplies?

80 PLUS® is an international certification system that confirms that a computer power supply efficiently converts electrical energy with minimal losses. The less energy is lost as heat during operation, the more goes to maintaining a stable electric output to power the PC.

To get 80 PLUS® certification, a PSU should comply with the following indicators:

  • ensure at least 80 % efficiency at 20 %, 50% and 100 % load;
  • have a power factor (PF) of 0.9 or higher.

There are several levels based on efficiency:

  1. Standard (80 %).
  2. Bronze, Silver, Gold, Platinum, Titanium (85 % – 94 %).
  3. Ruby, the newest level, is designed for server/central units (up to 96.5 %).

In general, the higher the 80 PLUS® certification level, the less energy is wasted as heat—even under peak load conditions. Improved efficiency not only reduces power consumption but also helps extend the PSU’s lifespan, especially when supported by effective internal cooling. A PSU with 80 PLUS® certification ensures reliable, high-performance operation across all load levels, whether you’re handling everyday tasks, intensive gaming sessions, or overclocking.

How does the 80 PLUS® rating system work?

The idea behind the 80 PLUS® rating is simple: it measures how efficiently a power supply converts electricity from the wall into usable power for your computer and how stable this electricity stays under different workloads.

Here’s how it works. Power supplies are tested by an independent organization (CLEAResult) in a certified lab, using standardized procedures. They check how much of the energy pulled from the wall outlet actually goes to your PC, and identify how much is lost as heat. Tests are done at different load levels. At first, checking at 0 % load, then 15 minutes at each load level, usually, 20 %, 50 %, and 100 %. When talking about Titanium and Ruby PSU certifications – models are also tested at 10 % or even 5 % load for extra accuracy.

Based on the test results, the PSU receives a rating: Bronze, Silver, Gold, Platinum, Titanium (or Ruby for servers), each progressing with stricter efficiency thresholds as we go higher. Testing stops if the power supply doesn’t meet requirements, so the PSU doesn’t get certified. All certified models and their test results are available on the CLEAResult public online portal. 

In March 2025, CLEAResult introduced a new Ruby category, used mainly for data centers. This rating achieves a minimum of 96.5 % efficiency at 50 % load and can also maintain high efficiency (90 % TO 95 %), even at 5 %, 20 % and 100 % load levels. 

The 80 PLUS® certification system measures how much energy is converted by the PSU under varying conditions in an accurate, transparent, and repeatable way. This procedure guarantees users that the certified units are energy efficient, stable, and reliable in the long term.

What are the differences between Bronze, Silver, Gold, Platinum, and Titanium levels?

The key difference between the 80 PLUS® certifications lies in power supply efficiency. Each level is based on how well the PSU performs under different loads. These loads vary, and usually are measured at 20 %, 50 %, and 100 %. With a higher certification level, the PSU works more efficiently, wasting less energy as heat and saving more electricity overall.

The PSU certification levels can be summarized as follows:

Certification Level20 % Power load50 % Power load100 % Power loadPower factor
Bronze82 %85 %82 %PF ≥ 0.90
Silver85 %88 %85 %PF ≥ 0.90
Gold87 %90 %87 %PF ≥ 0.90
Platinum90 %92 %89 %PF ≥ 0.95
Titanium90 %94 %90 %PF ≥ 0.95 (plus extra test under 10 %)

Why does PSU efficiency matter for modern PC builds?

Power supply efficiency is crucial for modern PCs. It affects not only energy consumption but also overall system stability. 

PSUs with high efficiency ratings ( 80 PLUS® Gold certification and above) convert more electricity into useful power for components and lose less in the form of heat. That means that all power goes right to your PC components to handle the current tasks. 

High power supply efficiency reduces heat buildup inside the PSU itself, which lessens the strain on its cooling system, lowers fan noise, and helps extend the lifespan of internal PSU components. Furthermore, energy-efficient PSUs save you money, especially when you use powerful systems that constantly run 24/7. 

PSUs with Gold, Platinum, or Titanium certification levels may cost more initially, but their higher efficiency reduces heat stress, contributing to greater long-term reliability and lower energy costs. In the end, with a high-quality power supply, your PC runs well and you can keep focusing on work, games, or enjoy everyday tasks without a hitch.

Can a higher PSU efficiency rating reduce system heat and fan noise?

Yes, it can! PSUs with higher efficiency ratings (Gold, Platinum, Titanium) consume less power than unrated power supplies. This also means that they waste less energy, which reduces heat generation and, consequently, there will be less load on the cooling system. When the fans are running at slower speeds, noise is also kept to a minimum. In the end, a high-efficiency power supply positively affects the service life of not only its components but also those of your entire PC. 

Users of 80 PLUS® Platinum and Titanium certified power supplies generally note the reduced temperature inside the case. The fans run more quietly, ensuring smooth PC operation without extraneous or loud noises, which can be important during game sessions, overclocking, long-time tasks, or just for your general well-being.

In summary, power supplies with 80 PLUS® Gold certification and above are not only more reliable but also more efficient; they generate less heat and require less intensive cooling, they reduce system noise, and make working or playing on your PC more comfortable.

Does an efficient power supply improve hardware longevity?

In one word, yes! An efficient PSU has a positive effect on the hardware’s longevity. There are a few reasons to prove this statement. First, a highly efficient power supply generates less heat, which lowers the temperature inside the case, which in turn reduces the load on all components to support a reliable PC performance over time. At lower temperatures, the PSU’s internal components, like for example its capacitors, wear out more slowly.

Energy-efficient models (with 80 PLUS® Platinum and Titanium certification) are usually made from more reliable materials to contribute to the overall system reliability. It is worth noting that high-quality power supplies usually provide stable power without voltage fluctuations, which reduces the risk of damage to critical components, such as the processor, the video card, or the motherboard.

What 80 PLUS® certification level should you choose for gaming, workstations, or servers?

There’s a difference in energy consumption and PC performance under different circumstances for the typical tasks you will use your PC for. Based on your requirements for performance, we recommend choosing a PSU with the help of the Seasonic PSU wattage calculator, which will also give you recommendations for an appropriate 80 PLUS® certification level that you might need to ensure sufficient power for your PC components and a smooth, enjoyable user experience.
