The White Rating PSU, also known as the 80 PLUS White certification, is an entry-level efficiency rating for power supplies. The 80 PLUS certification program is a widely recognized and respected standard for measuring the efficiency and performance of power supplies. In this article, we will delve into the details of the White Rating PSU, its efficiency, and what it means for users.
Understanding the 80 PLUS Certification
The 80 PLUS certification program is a voluntary program that tests and certifies power supplies based on their efficiency. The program awards certifications based on the power supply’s efficiency at 20%, 50%, and 100% loads. The certifications range from 80 PLUS White to 80 PLUS Titanium, with each level representing a higher level of efficiency. The 80 PLUS White certification is the entry-level certification, requiring a minimum efficiency of 80% at 20% load, 80% at 50% load, and 80% at 100% load.
Efficiency Levels of 80 PLUS Certification
The 80 PLUS certification program has several levels of certification, each with its own set of efficiency requirements. The levels are as follows:
| Certification Level | 20% Load Efficiency | 50% Load Efficiency | 100% Load Efficiency |
|---|---|---|---|
| 80 PLUS White | 80% | 80% | 80% |
| 80 PLUS Bronze | 82% | 85% | 82% |
| 80 PLUS Silver | 85% | 88% | 85% |
| 80 PLUS Gold | 90% | 92% | 90% |
| 80 PLUS Platinum | 92% | 94% | 90% |
| 80 PLUS Titanium | 94% | 96% | 94% |
The 80 PLUS White certification is the most basic level of certification, requiring a minimum efficiency of 80% at all three load levels.
Benefits of Using a White Rating PSU
While the White Rating PSU may not be the most efficient power supply available, it still offers several benefits to users. Some of the benefits include:
- Energy Savings: A White Rating PSU can help users save energy and reduce their electricity bills. Although it may not be as efficient as higher-rated power supplies, it still meets the minimum efficiency requirements of the 80 PLUS certification program.
- Reliability: Power supplies with the 80 PLUS White certification are designed to provide reliable performance and meet the minimum standards for efficiency and reliability.
- Affordability: White Rating PSUs are generally more affordable than higher-rated power supplies, making them a cost-effective option for users who do not require high levels of efficiency.
Overall, the White Rating PSU is a good option for users who are looking for a reliable and affordable power supply that meets the minimum standards for efficiency.

Overall, White Rating PSUs offer a good balance of performance and affordability, making them a popular choice for budget-friendly systems.
What is the difference between 80 PLUS White and 80 PLUS Bronze certifications?
+The main difference between 80 PLUS White and 80 PLUS Bronze certifications is the level of efficiency required. 80 PLUS White requires a minimum efficiency of 80% at all three load levels, while 80 PLUS Bronze requires a minimum efficiency of 82% at 20% load, 85% at 50% load, and 82% at 100% load.
Are White Rating PSUs suitable for gaming systems?
+White Rating PSUs can be suitable for gaming systems, but it depends on the specific requirements of the system. If the system requires a high level of efficiency and performance, a higher-rated power supply may be more suitable. However, if the system has a moderate power requirement, a White Rating PSU may be sufficient.
In conclusion, the White Rating PSU is a good option for users who are looking for a reliable and affordable power supply that meets the minimum standards for efficiency. While it may not be the most efficient power supply available, it still offers several benefits, including energy savings, reliability, and affordability. By considering the specific needs of your system and choosing a power supply that meets those needs, you can ensure optimal performance and efficiency.
