Price Comparison

The CORSAIR RM850e is priced at £85.99, while the Be Quiet! Pure Power 13M ATX 3.1 is more expensive at £108.79. The difference in price is £22.80, which positions the CORSAIR RM850e as a more budget-friendly option for consumers seeking a reliable power supply. This price difference may influence buyers who are looking to optimise their spending without sacrificing quality. With the CORSAIR model offering a robust feature set at a lower cost, it presents a compelling choice for those building or upgrading their PCs.

Modular Design

The CORSAIR RM850e boasts a fully modular design, allowing users to connect only the cables necessary for their specific system builds. This feature not only enhances cable management but also aids in airflow within the case. In contrast, the Be Quiet! Pure Power 13M ATX 3.1 lacks detailed information about its modular design capabilities, which suggests it may not offer the same level of flexibility. For PC builders who prioritise aesthetics and efficient cable management, the modularity of the CORSAIR RM850e may be a significant advantage.

Efficiency Standards

The CORSAIR RM850e is Intel ATX 3.1 certified and supports the PCIe 5.1 platform, providing a robust solution for modern gaming and high-performance systems. This certification ensures that the power supply can handle transient power excursions from GPUs efficiently. The Be Quiet! Pure Power 13M also meets the ATX 3.1 standard, but specific efficiency ratings such as the 80 Plus Gold certification are not explicitly mentioned in the data provided. The clear efficiency advantage of the CORSAIR RM850e, emphasised by its certification, might appeal to users looking for reliable performance under load.

Noise Levels

The CORSAIR RM850e features a 120mm rifle bearing fan designed to minimise noise, even under full load. This makes it a suitable choice for users who prefer a quieter operation, especially in gaming or multimedia setups. The Be Quiet! Pure Power 13M is marketed under the brand name "Be Quiet!" but lacks specific noise-related features or measurements in the provided data. For those who value a low-noise computing experience, the performance of the CORSAIR RM850e in this regard is a distinct advantage.

Component Reliability

With 105°C-rated capacitors, the CORSAIR RM850e promises steady and reliable power delivery, which is crucial for high-performance components. This feature indicates a commitment to quality and reliability, particularly during intense usage scenarios. The Be Quiet! Pure Power 13M does not provide comparable details regarding its internal components, leaving potential buyers in the dark about its reliability. For those looking to invest in a power supply that promises durability and consistent performance, the CORSAIR RM850e stands out as the more trustworthy option.

Compatibility Features

The CORSAIR RM850e is designed for modern systems, ensuring compatibility with the latest hardware through its compliance with the ATX 3.1 power standard. This includes support for newer GPU technologies, which is incredibly important for gamers and power users. While the Be Quiet! Pure Power 13M is also ATX 3.1 compliant, the lack of additional information about its features makes it difficult to assess its compatibility fully. The clear emphasis on modernity and compatibility in the CORSAIR model could be a deciding factor for users investing in the latest technology.

Brand Reputation

Corsair has a well-established reputation in the PC component market, particularly for power supplies, with a strong focus on performance and customer satisfaction. Be Quiet! also has a solid reputation, particularly in the realm of quiet computing, but its offering here lacks the detailed specifications that would typically accompany high-quality power supplies. The established trust in Corsair's products may sway buyers towards the RM850e, especially for those who have had positive experiences with the brand in the past.

Which should you buy?

Ultimately, the choice between the CORSAIR RM850e and the Be Quiet! Pure Power 13M ATX 3.1 boils down to specific user needs and preferences. The CORSAIR RM850e offers superior features such as full modularity, efficiency certifications, low noise levels, and reliable components at a lower price of £85.99. In contrast, the Be Quiet! Pure Power 13M, while reputable, does not provide sufficient information to warrant its higher price of £108.79. For consumers prioritising value, performance, and modern features, the CORSAIR RM850e is the clear winner in this comparison.
