CORSAIR RM850e vs Mean Well EDR-120-24 Single Output DIN Rail Power Supply 24V 5 Amp 120W

Overview of the Products

When it comes to power supplies, the CORSAIR RM850e and the Mean Well EDR-120-24 serve distinct purposes and audiences. The CORSAIR RM850e is a high-capacity power supply designed for gaming and high-performance PCs, while the Mean Well EDR-120-24 is tailored for industrial applications requiring a stable and regulated output. This comparison will explore their features, performance, pricing, and suitability for various applications.

Pricing Comparison

The CORSAIR RM850e is priced at C$184.99, which positions it as a premium option in the consumer power supply market. In contrast, the Mean Well EDR-120-24 is significantly more affordable, retailing at C$42.99. This substantial price difference reflects the intended use cases; the RM850e is built for demanding systems with higher power requirements, while the EDR-120-24 caters to low to moderate power needs in industrial settings. Customers should consider their budget and the specific power demands of their applications when evaluating these options.

Power Output and Performance

The CORSAIR RM850e boasts a maximum output of 850 watts, making it suitable for high-performance gaming rigs and workstations that demand considerable power. On the other hand, the Mean Well EDR-120-24 has a maximum output of 120 watts, offering a stable 24V and 5-amp output, which is adequate for many industrial devices. This stark difference in power output means that the RM850e is far more versatile when it comes to powering multiple high-demand components, while the EDR-120-24 is limited to specific, lower-power applications.

Build Quality and Reliability

The CORSAIR RM850e features 105°C-rated capacitors, which are designed to provide reliable and stable power under varying loads. This rating ensures that the power supply can handle high temperatures without compromising performance. Conversely, the Mean Well EDR-120-24 focuses on simplicity and efficiency, providing a robust 24V output tailored for industrial use. While both power supplies are built to last, the RM850e's higher-grade components may offer better durability in high-demand scenarios.

Modularity and Installation

The CORSAIR RM850e is a fully modular power supply, allowing users to connect only the cables they need for their system build. This modularity helps reduce cable clutter and improve airflow within the case, making installation easier and more efficient. In contrast, the Mean Well EDR-120-24 is designed for DIN rail mounting, which is ideal for industrial environments where space-saving and ease of installation are critical. The choice between these designs largely depends on the user's specific installation needs—either a clean, custom build or straightforward industrial setup.

Noise Levels

One of the standout features of the CORSAIR RM850e is its low-noise operation, achieved through a 120mm rifle bearing fan and a calculated fan curve. This design keeps fan noise to a minimum, even under full load, making it an excellent choice for users who prioritize a quiet computing environment. The Mean Well EDR-120-24 does not focus on noise levels, as it is typically used in environments where noise is less of a concern. Thus, if noise reduction is a criterion, the RM850e excels in this area.

Compatibility and Standards

The CORSAIR RM850e is Intel ATX 3.1 certified, meaning it meets modern power standards and can support the latest components, including PCIe 5.1 platforms. This certification is crucial for future-proofing a gaming or high-performance setup. On the other hand, the Mean Well EDR-120-24 is designed for compatibility with industrial applications that require a stable 24V output. The choice of power supply will largely depend on whether the user is building a consumer-grade PC or setting up industrial equipment.

User Experience and Support

The CORSAIR RM850e is aimed at gamers and PC builders, and it often comes with a user-friendly installation manual, along with a reputation for strong customer support. Users can expect a seamless experience when integrating the RM850e into their builds. The Mean Well EDR-120-24, while robust, is typically used in industrial settings where technical support resources may vary. Users should evaluate the availability of support for either product based on their specific needs.

Which should you buy?

Deciding between the CORSAIR RM850e and the Mean Well EDR-120-24 ultimately hinges on your specific power requirements and intended use. If you are assembling a high-performance gaming rig or workstation that demands substantial power, the CORSAIR RM850e, with its 850 watts of output and premium features, is the clear choice at C$184.99. However, if you need a reliable power supply for industrial applications where stability at a lower output is paramount, the Mean Well EDR-120-24 at C$42.99 is an excellent and budget-friendly option. Your choice should align with the demands of your system and the environment in which the power supply will be used.
