Cooler Master V850 SFX Gold vs CORSAIR CX650 80 PLUS Bronze Non Modular Low-Noise ATX 650 Watt Power Supply - U

Introduction to Power Supplies

When it comes to powering your PC, choosing the right power supply unit (PSU) is crucial. The Cooler Master V850 SFX Gold and the Corsair CX650 80 PLUS Bronze are two compelling options, each catering to different needs and preferences. The Cooler Master V850 is priced at £134.56, whereas the Corsair CX650 is considerably more affordable at £44.99. This article will dissect the features, performance, and overall value of each to help you determine which PSU best suits your build.

Efficiency and Certification

Efficiency is a key consideration when selecting a PSU, and this is where the Cooler Master V850 SFX Gold shines with its 80 PLUS Gold certification. This certification guarantees an efficiency of 90% under typical loading, which can significantly reduce energy costs and heat output. In contrast, the Corsair CX650, while still efficient with its 80 PLUS Bronze certification, operates at up to 88% efficiency. Although both provide substantial energy savings, the Cooler Master’s superior efficiency makes it a better choice for high-demand systems.

Design and Size

Size can be a decisive factor, especially for compact builds. The Cooler Master V850 SFX Gold is designed specifically for small form factor (SFF) cases, with compact dimensions of 100 x 125 x 63.5 mm. Alternatively, the Corsair CX650 has a more standard size at 125mm in length, making it compatible with most modern PC cases. If you are working within tight spaces, the Cooler Master’s SFX form factor may offer a more tailored fit, while the Corsair provides flexibility for larger builds.

Modular Cabling

Cabling can significantly affect the airflow and aesthetics of your build. The Cooler Master V850 SFX Gold features fully modular cabling, allowing you to connect only the cables you need, which enhances internal ventilation and leads to a cleaner look. Conversely, the Corsair CX650 is non-modular, meaning all cables are permanently attached. This could lead to unnecessary clutter if not all cables are used. For users prioritising clean builds and airflow, the Cooler Master’s fully modular design is a distinct advantage.

Cooling Solutions

Cooling is essential to maintain optimal performance and longevity of components. The Cooler Master V850 SFX Gold employs a 92mm fluid dynamic bearing (FDB) fan, designed to keep noise levels low and maintain efficient cooling. Furthermore, it features a semi-fanless mode that activates only under heavy loads, further reducing noise during light use. The Corsair CX650, on the other hand, utilises a 120mm thermally controlled fan that only ramps up in speed under heavy stress. While both units focus on low noise, the Cooler Master’s advanced fan design provides additional benefits in quiet operation.

Build Quality and Warranty

Durability is another critical factor when investing in a PSU. The Cooler Master V850 SFX Gold boasts high-quality components, including 100% Japanese capacitors, which contribute to its long-term reliability. Additionally, it comes with a 10-year warranty, providing peace of mind for long-term users. In contrast, specific details about the build quality of the Corsair CX650 are not highlighted, and while it is backed by Corsair’s reputation, it does not offer a warranty period as extensive as its counterpart. This makes the Cooler Master a more reliable choice for those who want assurance in their investment.

Price Point Considerations

Price can often dictate a consumer's choice. The Cooler Master V850 SFX Gold is priced at £134.56, which reflects its high-end features and efficiency. Conversely, the Corsair CX650 is a budget-friendly option at just £44.99, making it accessible for those who are cost-conscious. However, while the Corsair is significantly cheaper, it may not provide the same level of efficiency, modularity, and build quality that the Cooler Master offers. Thus, potential buyers must weigh the importance of features against their budget constraints.

User Experience and Application

Considering the target audience is essential for both products. The Cooler Master V850 SFX Gold is ideal for gamers and professionals who require a compact, high-efficiency PSU for demanding builds. Its modularity and cooling features cater to advanced users who prioritise performance and aesthetics. In contrast, the Corsair CX650 is suited for mainstream users looking for a reliable power supply for general computing needs. Its low noise and sufficient efficiency make it an attractive choice for budget builds. Ultimately, your application will help determine which PSU is the best fit.

Which should you buy?

The decision between the Cooler Master V850 SFX Gold and the Corsair CX650 boils down to your specific needs and budget. If you are looking for a high-efficiency, modular power supply with excellent cooling and build quality, the Cooler Master V850 is the clear winner, albeit at a higher price of £134.56. However, if you are on a budget and need a reliable power supply for a standard build, the Corsair CX650 offers great value at only £44.99. Consider your priorities—whether they lean towards performance or cost—before making your final choice.
