be quiet! Pure Power 13 M 1000W Power Supply vs NZXT C850 SFX Gold - 850W SFX ATX 3.1 Power Supply - 80 Plus Gold - Cybenetics P

Pricing Comparison

When it comes to pricing, the be quiet! Pure Power 13 M 1000W Power Supply is significantly more affordable at £99.99 compared to the NZXT C850 SFX Gold, which is priced at £129.98. The £29.99 difference in price might influence buyers who are looking for a cost-effective power supply solution without compromising on essential features. Despite being the more economical option, the be quiet! model offers a robust 1000W output, making it a compelling choice for those seeking high performance on a budget. In contrast, while the NZXT provides a lower 850W capacity, its compact SFX form factor might justify the higher price for specific use cases.

Power Output and Efficiency

The be quiet! Pure Power 13 M delivers 1000W of continuous power, making it suitable for high-performance systems, particularly those with demanding graphics cards. It boasts an 80 PLUS Gold certification with an impressive efficiency rating of up to 94.4%. This high efficiency translates to lower power consumption and reduced electricity costs over time. On the other hand, the NZXT C850 offers 850W, also certified with 80 PLUS Gold but with Cybenetics Platinum efficiency ratings. This indicates that while both models are energy-efficient, the be quiet! model provides a higher power output, making it better suited for power-hungry builds.

Form Factor and Compatibility

The NZXT C850 is designed in an SFX form factor, which is specifically optimised for compact builds, allowing for maximum space efficiency in small form factor (SFF) cases. This makes it an excellent choice for gamers and professionals who may be limited on space. Conversely, the be quiet! Pure Power 13 M follows the standard ATX format, which is compatible with a wider range of cases. While the ATX size offers more installation flexibility, the compact nature of the NZXT may appeal to users prioritising a smaller overall footprint for their builds.

Cooling and Noise Levels

In terms of cooling and noise levels, the be quiet! Pure Power 13 M features a fan that completely turns off under low load, ensuring silent operation during less demanding tasks. This is ideal for users who desire a quiet system. The NZXT C850, equipped with a 92 mm fluid dynamic bearing (FDB) fan, also prioritises silent operation with its Zero RPM mode. However, it boasts a Cybenetics A- noise rating, suggesting it operates quietly but may not match the silent capabilities of the be quiet! model under low loads. Both units are engineered for quiet performance, but the be quiet! may have the edge in terms of silence during low power usage.

Cable Management and Modularity

The be quiet! Pure Power 13 M offers modularity that simplifies cable management, allowing users to leave out unnecessary cables for a cleaner build. This not only enhances aesthetics but also improves airflow within the case, resulting in lower temperatures. In contrast, the NZXT C850 is designed to deliver full power capabilities in a compact size, which may limit some aspects of cable management due to its smaller dimensions. While both power supplies aim to provide tidy installations, the be quiet! model's modular design may offer a more streamlined approach for users concerned about cable clutter.

Reliability and Protection Features

Both power supplies come with features that ensure reliable performance and protection for components. The be quiet! Pure Power 13 M is noted for its ability to handle power excursions up to double its rated power, providing a safety net for demanding graphics cards. Additionally, its LLC topology offers excellent voltage regulation and efficiency. Meanwhile, the NZXT C850 emphasises its low ripple noise and tight voltage regulation to help maintain system stability. Both units are designed to protect components and ensure uninterrupted performance, but the be quiet! may provide an additional layer of reliability for high-power scenarios.

Target Audience

The target audience for the be quiet! Pure Power 13 M includes gamers and PC builders who require a high-output, cost-effective solution that prioritises silence and modularity. Its specifications make it ideal for users who are looking to build powerful gaming rigs or media creation PCs. Conversely, the NZXT C850 is aimed at users who favour compact builds without sacrificing power. Its SFX design makes it particularly appealing to those with limited space who still want a reliable power source for modern graphics cards. Each product caters to distinct needs, influencing buyer decisions based on individual system requirements.

Which should you buy?

In deciding between the be quiet! Pure Power 13 M 1000W and the NZXT C850 SFX Gold 850W, the choice largely depends on your specific needs. If you're looking for a higher power output, superior efficiency, and an economical price point, the be quiet! model is the clear winner, offering exceptional value at £99.99. However, if you require a compact power supply for a small form factor build, and you are willing to pay a premium for that convenience, the NZXT C850 at £129.98 could be the better option. Ultimately, both power supplies excel in their respective niches, making them strong contenders in the power supply market.
