Cooler Master V850 SFX Gold vs Corsair RM850e

Price Comparison

The Cooler Master V850 SFX Gold is priced at £134.56, while the Corsair RM850e is significantly more affordable at £92.99. This makes the Corsair model £41.57 less expensive. The price difference may be a crucial factor for budget-conscious consumers looking to build or upgrade their systems without compromising on quality and performance.

Form Factor

The Cooler Master V850 SFX Gold is specifically designed for small form factor (SFF) mini-ITX cases, measuring 100 x 125 x 63.5 mm. This compact design allows for versatile installations, including within ATX cases using an SFX-to-ATX bracket. In contrast, the Corsair RM850e does not specify a particular form factor but is a fully modular PSU, allowing users to connect only the necessary cables for their builds. While both power supplies aim to cater to different case sizes, the Cooler Master has a definitive advantage for those prioritising compact builds.

Efficiency Ratings

When it comes to efficiency, the Cooler Master V850 SFX Gold boasts an 80 PLUS Gold rating, indicating up to 90% efficiency under typical loading conditions. This high efficiency not only reduces energy costs but also minimises heat accumulation, which can improve overall system performance. The Corsair RM850e does not have a specified efficiency rating but is Intel ATX 3.1 certified, suggesting it meets modern efficiency standards. However, the explicit 80 PLUS Gold rating of the Cooler Master provides a clearer advantage in terms of energy efficiency.

Noise Levels

The Cooler Master V850 SFX Gold features a 92mm fluid dynamic bearing (FDB) fan that operates quietly and includes a semi-fanless mode when under 15% maximum load. This design prioritises both temperature control and noise reduction. On the other hand, the Corsair RM850e is equipped with a 120mm rifle bearing fan, which is engineered to maintain low noise levels even under full load. While both models aim for quiet operation, the specific semi-fanless capability of the Cooler Master may appeal to users seeking a silent experience during low-load scenarios.

Cable Management

The Cooler Master V850 SFX Gold’s fully modular cabling system allows for superior cable management, aiding in creating sophisticated builds and improving internal ventilation. It includes multiple connectors such as ATX 24 Pin, EPS 4+4, and PCI-e 6+2 Pin, among others. The Corsair RM850e also offers fully modular cabling, which ensures that users can connect only the cables they need. While both power supplies provide excellent cable management options, the Cooler Master’s broader range of connectors may offer additional flexibility for custom builds.

Component Quality

In terms of component quality, the Cooler Master V850 SFX Gold is built with 100% Japanese capacitors, ensuring long-term reliability and performance. Additionally, it comes with a generous 10-year warranty, providing peace of mind to users. The Corsair RM850e features 105°C-rated capacitors, which also indicates a commitment to quality and reliability. However, the extended warranty of the Cooler Master could be a significant factor for those prioritising longevity in their investment.

Compatibility

The Cooler Master V850 SFX Gold is explicitly designed for small form factor builds but can also be fitted into larger ATX cases with the appropriate bracket. This dual compatibility makes it a versatile choice for a variety of builds. The Corsair RM850e, while not specified for a particular case size, is compliant with the ATX 3.1 power standard and supports the PCIe Gen 5.1 platform, making it suitable for modern high-performance systems. Both options offer strong compatibility, but the Cooler Master shines in its specific design for compact cases.

Which should you buy?

Choosing between the Cooler Master V850 SFX Gold and the Corsair RM850e ultimately depends on your specific needs and budget. If you require a compact power supply for a small form factor build and value high efficiency and a long warranty, the Cooler Master is the superior choice despite its higher price of £134.56. However, for those on a tighter budget who still want a reliable and efficient power supply, the Corsair RM850e at £92.99 offers significant value with its modern certifications and quiet operation. The decision boils down to whether you prioritise specific features and build quality over cost.
