Power Efficiency Comparison

In terms of efficiency, the CORSAIR RM850x holds a commendable Cybenetics Gold-Certification, indicating up to 91% efficiency. This is a significant factor for users concerned about energy consumption and heat generation. On the other hand, the Asus ROG Strix 1200W Platinum boasts GaN MOSFET technology, which enhances efficiency by up to 30%. While the RM850x focuses on a solid efficiency rating, the ROG Strix's technology offers a more advanced approach to power management, particularly for high-demand scenarios. The choice between these two units may hinge on whether you prioritise a proven efficiency rating or cutting-edge technology.

Modularity and Installation

The CORSAIR RM850x features a fully modular design, allowing users to connect only the cables they need, which not only simplifies installation but also improves airflow within the case. This design is particularly beneficial for custom builds where cable management is crucial. Meanwhile, the Asus ROG Strix also offers modularity, although specific details about its design are not highlighted in the data. The direct GPU connection provided by the RM850x eliminates the need for adapters, further enhancing ease of installation. For users who value clean builds and straightforward setups, the RM850x appears to have an edge in terms of modularity.

Thermal Performance

Thermal performance is a vital aspect of any power supply, particularly for gaming rigs that operate under heavy loads. The CORSAIR RM850x is designed for low noise operation, contributing to a quieter system overall. Its efficient cooling solutions help maintain lower temperatures, which can be crucial for system stability. In contrast, the Asus ROG Strix is equipped with large heatsinks that cover critical components to ensure lower temperatures and reduced noise levels compared to reference designs. The dual ball fan bearings also contribute to better thermal management, suggesting that both power supplies excel in keeping temperatures in check, albeit through different methods.

Noise Levels

Noise levels are an important consideration for many users, especially those who prefer a quiet gaming environment. The CORSAIR RM850x is specifically marketed as a low-noise power supply, making it an attractive option for those sensitive to sound. The Asus ROG Strix incorporates 0dB technology, allowing for silent operation during light gaming sessions. This feature can be particularly appealing for users who do not want their power supply to be a source of distraction. While both units offer quiet operation, the RM850x explicitly focuses on low noise, which may sway buyers who prioritise silence in their setups.

Price Comparison

When it comes to pricing, the CORSAIR RM850x is markedly more affordable at £124.40 compared to the Asus ROG Strix's £179.99. This price difference of £55.59 can be significant for budget-conscious consumers. The RM850x offers a blend of reliability and performance, making it an excellent choice for those who want quality without breaking the bank. Conversely, the ROG Strix commands a premium price but justifies it with advanced features and higher power output, targeting enthusiasts who may require the extra wattage for high-performance components.

Which should you buy?

Ultimately, the choice between the CORSAIR RM850x and the Asus ROG Strix 1200W Platinum PSU boils down to your specific needs and budget. The RM850x is an excellent choice for users seeking a reliable, efficient, and quiet power supply at a competitive price. Its fully modular design also enhances ease of installation. However, if you require higher wattage and advanced features like GaN MOSFET technology and enhanced voltage delivery, the Asus ROG Strix may be worth the investment despite the higher cost. Assess your system requirements and budget to determine which power supply aligns best with your performance expectations.
