CORSAIR RM850e vs Asus ROG Strix 1200W Platinum PSU

Pricing

The price difference between the CORSAIR RM850e and the Asus ROG Strix 1200W Platinum PSU is significant, with the former priced at £85.99 and the latter at £179.99. This is a difference of £94, making the Asus option nearly double the cost of the Corsair unit. For budget-conscious consumers, the lower price of the CORSAIR RM850e offers an attractive entry point for those needing a reliable power supply without the premium features associated with higher-end models. Conversely, the Asus ROG Strix commands its higher price through enhanced features that may appeal to gamers and high-performance PC builders.

Power Efficiency

The Asus ROG Strix 1200W Platinum PSU boasts superior power efficiency, enhanced by its GaN MOSFET technology, which provides up to 30% better efficiency compared to traditional designs. This could lead to reduced electricity bills and better thermal management during extensive gaming sessions. In contrast, while the CORSAIR RM850e offers solid efficiency and is Intel ATX 3.1 certified, it does not explicitly claim the same level of efficiency improvements as the Asus unit. For users prioritising power efficiency and lower operational costs, the Asus ROG Strix presents a compelling case.

Cooling Solutions

Cooling is a critical consideration in power supplies, particularly for high-performance systems. The Asus ROG Strix features large heatsinks that cover critical components, resulting in reduced temperatures and noise levels compared to standard designs. Moreover, its dual ball fan bearings potentially last twice as long as sleeve bearing designs, ensuring longevity and reliability. On the other hand, the CORSAIR RM850e is equipped with a 120mm rifle bearing fan, designed to minimise noise even under full load. While both options focus on efficient cooling, the Asus ROG Strix seems to excel in thermal management and quiet operation under demanding conditions.

Modular Design

Both power supplies are fully modular, allowing users to connect only the cables necessary for their builds. This feature helps to reduce cable clutter and improve airflow within the case. The CORSAIR RM850e’s modularity is complemented by its low-noise operation, which can be particularly beneficial in quiet setups. The Asus ROG Strix also benefits from a well-organised internal layout, attributed to its advanced components. While both units perform similarly in terms of modularity, the additional design considerations of the Asus may provide a slight edge in maintaining an optimal internal environment.

Performance Stability

The Asus ROG Strix 1200W Platinum PSU features a unique "GPU-FIRST" voltage sensing technology, enhancing voltage delivery to the graphics card by up to 45%. This ensures smoother gameplay and more stable performance during high-demand situations. In comparison, the CORSAIR RM850e supports PCIe 5.1 and can withstand up to 2x transient power excursions from the GPU, ensuring reliable power delivery without dips. While both power supplies offer stability, the Asus unit’s emphasis on enhancing GPU performance may appeal to gamers looking for the best possible experience during intense sessions.

Noise Levels

Noise levels can greatly impact the user experience, especially in quiet environments. The CORSAIR RM850e is designed with a specially calculated fan curve that keeps fan noise to a minimum, even when operating at full load. This makes it an excellent choice for users who prioritise a silent operation. The Asus ROG Strix, on the other hand, employs 0dB technology, allowing for silent operation during light gaming. This feature can be especially appealing for users who alternate between gaming and quieter tasks. Between the two, the choice may depend on whether users prefer consistent low noise or silence during light usage scenarios.

Build Quality and Components

Both power supplies are built with high-quality components, but they cater to slightly different audiences. The CORSAIR RM850e utilises 105°C-rated capacitors, ensuring dependable electrical performance and longevity. This makes it suitable for users who seek reliability in their components. In contrast, the Asus ROG Strix's advanced features and design elements, such as its GaN MOSFETs and enhanced component cooling, indicate a build quality aimed at high-performance setups. For users focused on extreme performance and longevity under stress, the Asus ROG Strix might be the more appealing choice.

Which should you buy?

In conclusion, the choice between the CORSAIR RM850e and the Asus ROG Strix 1200W Platinum PSU largely depends on your specific needs and budget. If you are looking for a cost-effective, reliable power supply that offers solid performance for everyday gaming and general use, the CORSAIR RM850e at £85.99 is an excellent option. However, if you are a serious gamer or a high-performance PC builder who prioritises efficiency, cooling, and performance stability, the Asus ROG Strix with its premium features at £179.99 may justify the higher investment. Ultimately, both power supplies have their strengths, and your decision should align with your performance requirements and budget constraints.
