How to Guide                                                    

As one of the most essential components in a PC, the power supply unit (PSU) is responsible for delivering stable power to all other hardware. Choosing the wrong PSU can negatively impact your overall computing experience and even damage other components. Here’s a comprehensive guide to help you select the right power supply for your needs.

Power supplies are commonly available in three main form factors: ATX, SFX, and SFX-L.

The two most common power efficiency certifications are 80 PLUS and Cybenetics.

The 80 PLUS certification is the most widely recognized efficiency standard for PSUs. It ensures that a PSU operates at at least 80% efficiency under 20%, 50%, and 100% loads. The certification has multiple levels:

The Cybenetics certification is a newer and more precise PSU testing standard. It provides more detailed efficiency data than 80 PLUS and also includes a noise certification level, offering a more comprehensive PSU evaluation.

| Power Supply Form Factors |

Power supplies are commonly available in three main form factors: ATX, SFX, and SFX-L.



ATX Standard Power Supply





Dimensions: 150mm (W) × 86mm (H) × 140–200mm (D)



Compatible Cases: E-ATX / ATX / M-ATX



Features: The most widely used PSU standard, compatible with most mainstream PC cases.





SFX Small Form Factor Power Supply





Dimensions: 125mm (W) × 63.5mm (H) × 100mm (D)



Compatible Cases: Small M-ATX / ITX



Features: Designed mainly for ITX cases, smaller in size but can be installed in ATX cases using an SFX to ATX adapter.



SFX-L Small Form Factor Power Supply





Dimensions: 125mm (W) × 63.5mm (H) × 130mm (D)



Compatible Cases: Small M-ATX / ITX



Features: Compared to SFX, the depth is increased by 30mm, allowing for better cooling inside the PSU.



| Power Efficiency Certifications |

The two most common power efficiency certifications are 80 PLUS and Cybenetics.



80 PLUS Certification

The 80 PLUS certification is the most widely recognized efficiency standard for PSUs. It ensures that a PSU operates at at least 80% efficiency under 20%, 50%, and 100% loads. The certification has multiple levels:





Standard (White), Bronze, Silver, Gold, Platinum, and Titanium



Higher certification levels indicate better power efficiency, reducing energy waste and heat generation.



Cybenetics Certification

The Cybenetics certification is a newer and more precise PSU testing standard. It provides more detailed efficiency data than 80 PLUS and also includes a noise certification level, offering a more comprehensive PSU evaluation.

| Power Wattage Selection |

Choosing the right PSU wattage is essential. If the wattage is too low, your system may become unstable or shut down unexpectedly. You can estimate your needs using the OuterVision PSU calculator.



Example Build:





CPU: Intel Core i7-13700K



RAM: 16GB DDR4 × 2



GPU: Nvidia GeForce RTX 4070 Ti



Storage: M.2 SSD × 2



Usage:

Daily operation: 6 hours

High-load usage: 2 hours



OuterVision recommends a 660W PSU.To be safe, we suggest adding an extra 100–200W, making an 850W PSU a better choice.





Recommended PSU Wattage Based on GPU





Using integrated graphics or low-end GPU: 400–500W PSU



Mainstream gaming GPUs (e.g., RTX 4060, RTX 3060): 600–850W PSU (Bronze or Gold rated)



High-end flagship GPUs (e.g., RTX 5090, RTX 5080): 850W+ PSU (Gold or higher recommended)







By following these guidelines, you can find the ideal PSU for your system, ensuring both stability and efficiency.

A stable power supply is crucial for a smoothly running PC. In addition to ensuring compatibility with your case size, you should also pay close attention to certifications and power wattage.

How to Choose the Right Power Supply for Your PC

Cybenetics power supply efficiency certification is a performance rating standard introduced by Cybenetics Lab, an independent testing laboratory headquartered in Greece. This certification evaluates power supplies based on energy efficiency and noise levels. But how does it differ from the traditional 80 Plus certification?

| Efficiency Certification Levels (ETA) |

Cybenetics classifies efficiency into six levels, ranked from highest to lowest: Diamond, Titanium, Platinum, Gold, Silver, and Bronze.

The Cybenetics LAMBDA certification evaluates the noise levels of power supplies under different loads and categorizes them into A++, A+, A, A-, Standard++, Standard+, and Standard.

Cybenetics LAMBDA Noise Certification Ratings

One of the key differences between Cybenetics and 80 Plus certification is that Cybenetics includes noise testing. It categorizes power supplies based on noise levels at different loads, allowing consumers to choose a power supply with both high efficiency and low noise.

In contrast, 80 Plus certification only evaluates power conversion efficiency and does not measure noise levels.

Another major advantage of Cybenetics certification is its transparent reporting. Cybenetics publishes detailed test reports, including efficiency performance, noise levels, and additional data.

In comparison, 80 Plus certification only provides efficiency ratings without detailed breakdowns.

This comprehensive analysis should help you better understand Cybenetics certification and how it compares to the traditional 80 Plus standard.
