Price Comparison
The NZXT C850 Gold Core is significantly cheaper than the Cooler Master V850 SFX Gold. Priced at £89.99, the NZXT model provides a compelling option for budget-conscious consumers, while the Cooler Master comes in at £134.56. This difference of £44.57 may influence buyers who are looking for a cost-effective power supply without compromising on essential features.
The affordability of the NZXT C850 does not imply a lack of quality, as it still boasts an 80 PLUS Gold certification, ensuring efficient energy use. On the other hand, the Cooler Master V850, while more expensive, is designed specifically for small form factor builds, making it a suitable choice for users with compact setups. The choice between price and specific functionality is crucial in this comparison.
Efficiency Ratings
Both power supplies hold an 80 PLUS Gold certification, indicating their energy efficiency. However, the NZXT C850 further claims Cybenetics Platinum efficiency, which suggests it may outperform the Cooler Master V850 in energy savings during high-load scenarios. This efficiency is vital for users aiming to minimise their electricity costs while maintaining system performance.
The efficiency of the Cooler Master V850 is rated at 90% under typical loading conditions, making it a reliable choice for systems with high energy demands. The NZXT's additional Cybenetics rating may appeal to those prioritising energy efficiency in their builds, especially when operating under heavy loads where heat generation can become a concern.
Design and Form Factor
The Cooler Master V850 SFX Gold is specifically designed for small form factor (SFF) mini-ITX cases, measuring just 100 x 125 x 63.5 mm. This compact design allows it to fit into tighter spaces, making it ideal for users who seek to build smaller, more efficient systems. Conversely, the NZXT C850 is an ATX power supply, which typically fits larger cases but may not be suitable for SFF builds.
The design choice may heavily influence user preference; those building compact systems may lean towards the Cooler Master for its form factor. However, the NZXT's wider compatibility with standard ATX cases offers flexibility for users who do not require a mini-ITX setup, presenting a trade-off between size and versatility.
Cooling Solutions
Cooling is a significant factor in power supply performance. The Cooler Master V850 features a 92mm fluid dynamic bearing (FDB) fan, which operates quietly and includes a semi-fanless mode when under 15% maximum load. This may result in quieter operation during low usage scenarios, appealing to users looking for a serene computing environment.
In comparison, the NZXT C850 is equipped with a larger 135mm fluid dynamic bearing fan that operates near-silently, achieving a noise rating of less than 15 dBA under light loads. The inclusion of a Zero RPM mode further enhances its quiet operation, making it an excellent choice for users who prioritise minimal noise levels. The difference in fan size and operation mode could sway users based on their noise sensitivity and cooling needs.
Modularity
The Cooler Master V850 boasts fully modular cabling, allowing for sophisticated cable management. This feature helps improve airflow within the case and reduces clutter, which is especially beneficial in compact setups. It includes connections for ATX, EPS, SATA, and PCIe, providing ample options for various components.
On the other hand, the NZXT C850 also offers modular cabling but does not highlight the extent of its modularity in the same detail as the Cooler Master. While it supports modern GPUs with its dual-color 12V-2x6 connector, users who value extensive customisation and optimal airflow might find the Cooler Master’s complete modularity more appealing.
Warranty and Durability
The Cooler Master V850 comes with an impressive 10-year warranty, reflecting the brand's confidence in the product's durability and longevity. This extended warranty provides peace of mind for users who plan to rely on their power supply for years, ensuring support in case of any failures.
In contrast, the warranty duration for the NZXT C850 is not mentioned, which could raise concerns regarding its long-term reliability. Users investing in power supplies often consider warranty as a critical aspect, and the Cooler Master's longer warranty may influence buyers seeking assurance in their investment.
Compatibility with Modern Hardware
The NZXT C850 is ATX 3.1 certified and ready for PCIe 5.1, making it suitable for next-generation GPUs, particularly modern NVIDIA graphics cards. This forward compatibility may be crucial for users planning to upgrade their systems with the latest technology.
The Cooler Master V850, while not explicitly noted for next-gen compatibility, is still a robust choice for existing hardware setups. However, users focused on future-proofing their systems may lean towards the NZXT’s modern certification, ensuring that their power supply can handle upcoming GPU requirements without issues.
Which should you buy?
Choosing between the Cooler Master V850 SFX Gold and the NZXT C850 Gold Core ultimately depends on your specific needs and preferences. If you’re building a compact mini-ITX system and value modularity and a longer warranty, the Cooler Master is the superior choice, albeit at a higher price of £134.56. Conversely, if you are looking for a more budget-friendly option that offers advanced compatibility with modern GPUs and quieter operation, the NZXT C850 at £89.99 stands out as an excellent alternative. Consider your build requirements, budget, and future upgrade plans to make the best decision.
