Cooler Master V850 SFX Gold vs NZXT C850 Gold ATX 3.1 - Fully Modular Low-Noise PC Gaming Power Supply - 850 Wa

Overview of the Power Supplies

In this comparison, we will explore two high-quality power supplies: the Cooler Master V850 SFX Gold and the NZXT C850 Gold ATX 3.1. The Cooler Master is priced at £134.56 while the NZXT is notably more affordable at £84.90. Despite the price difference, both products are designed to deliver exceptional performance for gaming and high-performance PCs, but they cater to different needs and preferences in terms of form factor and features.

Form Factor and Compatibility

The Cooler Master V850 SFX Gold is specifically designed for small form factor (SFF) mini-ITX PC cases, measuring just 100 x 125 x 63.5 mm. It can also be used in ATX cases thanks to its complementary SFX-to-ATX bracket. In contrast, the NZXT C850 Gold is an ATX power supply, which means it is larger and designed to fit standard ATX cases. This distinction makes the Cooler Master ideal for compact builds, while the NZXT is suited for more traditional setups, allowing users to choose based on their specific case requirements.

Efficiency Ratings

Efficiency is a crucial aspect when evaluating power supplies, and here the Cooler Master V850 SFX Gold shines with an 80 PLUS Gold rating, achieving up to 90% efficiency under typical loading. This high efficiency not only saves on utility costs but also reduces heat accumulation in the system. The NZXT C850 Gold also boasts strong efficiency, compliant with the ATX 3.1 standard, which enhances stability and power management. However, specific efficiency ratings for the NZXT are not provided, making it difficult to directly compare against the Cooler Master’s established performance.

Modular Cabling

Both power supplies offer fully modular cabling, which allows for efficient cable management and improved airflow within the case. The Cooler Master V850 SFX Gold features a comprehensive range of connectors including ATX 24 Pin, EPS 4+4, SATA, and PCI-e connectors, enabling versatile system configurations. The NZXT C850 Gold also supports modular cabling and is designed to provide stable power delivery, particularly to high-performance components such as NVIDIA GeForce RTX 50 Series graphics cards. This ensures that users can tailor their builds with minimal clutter and optimal airflow, making both choices excellent for advanced setups.

Cooling and Noise Levels

Cooling performance is vital for power supplies, and here we see a notable difference. The Cooler Master V850 SFX Gold uses a 92mm fluid dynamic bearing (FDB) fan that operates quietly and includes a semi-fanless mode for loads under 15%. This feature minimises noise during low usage periods, which is a significant advantage for builds prioritising a quiet operation. On the other hand, the NZXT C850 Gold employs a larger 135mm fluid dynamic bearing fan with a Zero Fan Mode, ensuring complete silence under 50% load. This makes the NZXT particularly appealing for users who want a power supply that remains whisper-quiet during regular operation.

Build Quality and Durability

Durability is a critical aspect of power supplies, and both the Cooler Master and NZXT models boast high-quality construction. The Cooler Master V850 SFX Gold is built using 100% Japanese capacitors, which enhance the unit's long-term reliability and performance, backed by a generous 10-year warranty. This assurance is significant for users looking for longevity in their investment. The NZXT C850 Gold also uses premium Japanese capacitors, which improve hold-up time and minimise ripple noise, ensuring stable power delivery. While both units are well-constructed, the extended warranty of the Cooler Master may provide additional peace of mind for users prioritising longevity.

Price Comparison

When it comes to price, the NZXT C850 Gold is significantly more affordable at £84.90 compared to the Cooler Master V850 SFX Gold, which is priced at £134.56. This price difference of £49.66 might be a deciding factor for budget-conscious consumers. While the Cooler Master offers advanced features tailored for compact builds, the NZXT provides an excellent balance of performance and affordability, making it a strong contender for users who may not require the specific advantages of the Cooler Master model.

Which should you buy?

Ultimately, the choice between the Cooler Master V850 SFX Gold and the NZXT C850 Gold ATX 3.1 depends on your specific needs and preferences. If you are looking for a compact power supply with high efficiency, excellent build quality, and a long warranty, the Cooler Master is an outstanding choice. However, if you are on a budget and need a reliable power supply for a standard ATX build with low noise operation, the NZXT offers great value without compromising on performance. Both power supplies have their strengths, so consider your system requirements and budget when making your final decision.
