The CORSAIR RM850e and the MONTECH Century II are both offerings from reputable brands in the power supply market. Corsair has a long-standing reputation for quality and reliability, while Montech is known for providing high-performance components at competitive prices. The CORSAIR RM850e is priced at £85.99, whereas the MONTECH Century II is available for a slightly lower price of £80.04. This price difference highlights the competitive nature of the power supply market, particularly in the high-end segment aimed at gamers and performance enthusiasts.

Power Output

Both power supplies offer a robust output of 850W, catering specifically to high-end gaming rigs and demanding applications. This power capacity ensures that users can run powerful GPUs and CPUs without fearing system instability. The CORSAIR RM850e is compliant with the latest Intel ATX 3.1 standard, supporting PCIe 5.1, which is essential for future-proofing your system. In contrast, the MONTECH Century II also meets ATX 3.1 and PCIe 5.1 requirements, making both options suitable for cutting-edge builds. This equivalence in power output makes either choice viable for users seeking performance.

Efficiency Ratings

In terms of efficiency, the MONTECH Century II boasts an 80 Plus Gold rating, while the CORSAIR RM850e is also positioned as a highly efficient power supply without a specific rating mentioned. Generally, an 80 Plus Gold certification indicates an efficiency of at least 87% at 20% and 100% loads, and at least 90% at 50% load. This makes the MONTECH Century II potentially more appealing for users prioritising energy efficiency. However, the lack of a specific rating for the CORSAIR does not necessarily imply lower efficiency, as Corsair products are known for their performance under various load conditions.

Noise Levels

The CORSAIR RM850e features a 120mm rifle bearing fan designed to keep noise levels low, even when operating at full load. This design consideration is crucial for gamers and professionals who require a quiet environment for their tasks. On the other hand, the MONTECH Century II does not specify its noise management features in the provided details. While this does not inherently mean it is noisier, the explicit mention of quiet operation in the CORSAIR RM850e gives it a distinct advantage for users who prioritise silent performance in their builds.

Build Quality and Components

The CORSAIR RM850e is noted for its use of 105°C-rated capacitors, which contribute to reliable electrical performance and a longer lifespan. This is a significant factor for users looking for long-term durability in their power supplies. The MONTECH Century II, while not detailing the temperature ratings of its components, does highlight its fully modular design and compliance with high standards, ensuring a good level of build quality. However, the explicit mention of high-quality capacitors in the CORSAIR unit suggests a potentially superior build quality that may appeal to discerning users.

Warranty and Support

When it comes to warranty, the MONTECH Century II offers an impressive ten-year warranty, reflecting the brand's confidence in its product durability and performance. In stark contrast, the warranty details for the CORSAIR RM850e are not specified, which can be a crucial consideration for prospective buyers. A longer warranty typically indicates a manufacturer's commitment to quality, providing peace of mind for users investing in a high-end power supply.

Aesthetic and Design

Both power supplies feature a fully modular design, allowing users to connect only the cables they need, which simplifies cable management and improves airflow within the case. The aesthetic design specifics are not provided, but Corsair products often have a sleek, professional appearance, while Montech may appeal to those looking for a more gamer-oriented design. The choice between them may ultimately depend on personal preference regarding visual appeal and how well they fit into a user's existing setup.

Which should you buy?

Choosing between the CORSAIR RM850e and the MONTECH Century II largely depends on your specific needs and preferences. If you value quiet operation, high-quality components, and the reliability associated with Corsair, the RM850e at £85.99 is a solid choice. However, if you're looking for a more budget-friendly option with an excellent warranty and competitive performance, the MONTECH Century II at £80.04 could be more appealing. Ultimately, both power supplies offer robust performance, but the decision may hinge on the importance of factors like noise level, warranty, and brand preference.
