Cooler Master V850 SFX Gold vs CORSAIR SF850

Overview of the Power Supplies

The Cooler Master V850 SFX Gold and the CORSAIR SF850 are both high-quality power supplies designed for compact systems. The V850 SFX Gold is priced at £134.56, while the SF850 comes at a higher price of £149.99. This comparison highlights their features, efficiency, and build quality, assisting you in choosing the right power supply for your needs.

Design and Form Factor

The Cooler Master V850 SFX Gold is specifically designed for small form factor (SFF) mini-ITX PC cases, with compact dimensions of 100 x 125 x 63.5 mm. This allows it to fit comfortably in tight spaces. On the other hand, the CORSAIR SF850 also employs a small SFX form factor, making it suitable for both compact and larger cases. Both power supplies are fully modular, promoting cleaner builds and improved airflow, but the SF850 supports the latest ATX 3.1 power standard, enhancing its future-proofing capabilities.

Efficiency Ratings

In terms of efficiency, the Cooler Master V850 SFX Gold boasts an 80 PLUS Gold rating, achieving up to 90% efficiency under typical loading conditions. This efficiency not only reduces electricity costs but also minimises heat output, which is crucial for compact systems. Conversely, the CORSAIR SF850 has an impressive 80 PLUS Platinum rating, indicating even higher efficiency and energy savings, making it an excellent choice for power-dense setups. The SF850’s superior rating suggests it is designed to handle demanding power requirements with less waste.

Cooling Solutions

Both power supplies are equipped with a 92mm fan designed to provide effective cooling while maintaining low noise levels. The Cooler Master V850 features a fluid dynamic bearing (FDB) fan, which helps keep temperatures down and includes a semi-fanless mode for quiet operation under low loads. The CORSAIR SF850 also utilises a PWM cooling fan with fluid dynamic bearings, ensuring efficient cooling without adding excessive noise. Both power supplies prioritise thermal management, but the semi-fanless mode of the V850 may appeal to users seeking quieter performance during light use.

Cable Management

The Cooler Master V850 SFX Gold features fully modular cabling, allowing users to connect only the cables they need for their build. This not only simplifies installation but also enhances internal airflow by reducing clutter. The CORSAIR SF850 also employs fully modular Type-5 Micro-Fit PSU connectors, which are designed to take up less space, further aiding in neat cable management. While both units excel in this area, the type of connectors used in the SF850 may offer additional compatibility benefits for specific builds.

Component Quality

Quality of components plays a significant role in determining the longevity and reliability of a power supply. The Cooler Master V850 SFX Gold is built with 100% Japanese capacitors, which are known for their reliability and durability. It also comes with a generous 10-year standard warranty, providing peace of mind for the user. In comparison, the CORSAIR SF850 also uses 105°C rated Japanese capacitors, enhancing its reliability. While both products utilise high-quality components, the extended warranty of the V850 could be a decisive factor for users prioritising long-term assurance.

Pricing Considerations

Pricing is a key factor in the decision-making process. The Cooler Master V850 SFX Gold is available for £134.56, making it the more budget-friendly option between the two. The CORSAIR SF850, priced at £149.99, is more expensive, reflecting its Platinum efficiency rating and advanced features. If budget is a primary concern, the V850 offers excellent performance at a lower price point, while the SF850 may justify its higher cost through its enhanced efficiency and compliance with the latest standards.

Which should you buy?

Choosing between the Cooler Master V850 SFX Gold and the CORSAIR SF850 ultimately depends on your specific needs and budget. If you seek a more affordable option with solid performance and a long warranty, the V850 is an excellent choice. However, if maximum efficiency, future-proofing, and slightly better build quality are your priorities, then the SF850 is worth the additional investment. Both power supplies are top-tier options suitable for compact builds, ensuring reliable power delivery for any system configuration.
