Power Supply 80+ Certification [Explained]

80+ certification is a voluntary standard for PSUs, indicating their efficiency in converting AC power to DC power.

Expert Verified By

You’ve probably encountered the “80 Plus” certification when purchasing a power supply unit. Have you ever wondered what it means? And why does it matter? If not, let me explain the 80+ certification and whether you should only consider it to get a suitable PSU.


Key Takeaways

  • 80+ certification is a voluntary standard for PSUs, indicating their efficiency in converting AC power to DC power.
  • The PSUs having 80 Plus are supposed to have 80% or more efficiency at load percentages of 20%, 50%, and 100%.
  • 80 Plus certification is not the best unit to measure because it uses some unrealistic or insufficient parameters for the power supply units.

What Is The 80+ Certification?

80+ certification is a voluntary standard for PSUs, indicating their efficiency in converting AC power to DC power[1]. The more efficient a PSU, the less energy it wastes in the form of heat. Wasting less heat leads to lower electricity bills and a reduced environmental impact.[2]

80+ Certification Levels

Certification Levels Efficiency @ 20% Load Efficiency @ 50% Load Efficiency @ 100% Load
80 Plus 80% 80% 80%
80 Plus Bronze 82% 85% 82%
80 Plus Silver 85% 88% 85%
80 Plus Gold 87% 90% 87%
80 Plus Platinum 90% 92% 89%
80 Plus Titanium 92% 94% 90%

Is The 80 Plus Best Unit To Measure PSU Efficiency?

The simple answer is No. 80 Plus is a helpful indicator. However, it is not the sole determinant of a good-quality PSU. Proper evaluation of PSU performance, reliability, and suitability for your gaming rig involves other testing parameters. Here are some essential things to consider besides 80 Plus.

  • Build Quality: High-quality PSU components and construction ensure the reliability and longevity of the hardware[3]. Choosing a PSU with a higher build quality is crucial in the selection process.
  • Voltage Ripple: Sometimes, fluctuations in output voltage can introduce electrical noise into your system, causing voltage ripple. This can degrade your system’s overall stability and performance[4].
  • Voltage Regulation: It is essential to consider how well a PSU maintains stable output voltage under different loads. Poor voltage regulation can lead to crashes and even hardware damage[5].
  • Over Power & Current Protection: OPP and OCP are safety features that shut down the PSU if it detects an overloaded power or current conditions. It ensures that the rig is safeguarded from potential harm.
  • Over Temperature Protection: This mechanism monitors the PSU’s internal temperature and shuts down if it exceeds safe operating limits, preventing overheating.
  • Transient Response: It measures how quickly a PSU can adjust its output voltage to compensate for sudden changes, especially in modern, more power-hungry PSUs.

These parameters are essential and can’t be overstated. Moreover, these features and parameters provide an extra layer of protection. Also, they increase the longevity and stability of your PC.
