be quiet! Pure Power 13 M 1000W Power Supply vs NZXT C850 Gold Core - 850W ATX 3.1 Power Supply - 80 PLUS Gold - Cybenetics Plat

Price Comparison

When it comes to pricing, the be quiet! Pure Power 13 M 1000W Power Supply is priced at £99.99, while the NZXT C850 Gold Core 850W Power Supply is slightly more affordable at £89.99. This represents a £10 difference, with the be quiet! model positioned as a premium option due to its higher wattage. The 1000W output of the be quiet! unit may justify the higher price for users looking for robust performance, especially in high-demand gaming setups or media creation PCs. Conversely, the NZXT model, with its 850W capacity, may appeal to those who need a reliable power supply at a lower price point without compromising on efficiency.

Efficiency Ratings

Efficiency is a crucial factor in power supplies, and both models boast impressive ratings. The be quiet! Pure Power 13 M achieves an 80 PLUS Gold certification with an outstanding efficiency rating of up to 94.4%. This high efficiency translates to lower power consumption, resulting in reduced electricity costs and cooler operation. On the other hand, the NZXT C850 Gold Core also boasts an 80 PLUS Gold certification but is additionally recognised with a Cybenetics Platinum efficiency rating. This indicates that while both units offer excellent energy efficiency, the NZXT may have an edge in performance under demanding loads.

Cooling and Quiet Operation

Both power supplies are designed for quiet operation, but they employ different methods to achieve this. The be quiet! Pure Power 13 M features a fan that turns off completely under low load, ensuring silent operation until more demanding tasks arise. This feature, combined with airflow-optimised fan blades, contributes to exceptionally quiet performance across various load scenarios. In comparison, the NZXT C850 Gold Core utilises a 135 mm fluid dynamic bearing fan that operates in a Zero RPM mode during light workloads, resulting in near-silent performance, particularly noted at less than 15 dBA. While both power supplies excel in quiet operation, the be quiet! model may have a slight advantage for users prioritising silence in all scenarios.

Connectivity Options

Connectivity features are essential for compatibility with modern systems, especially with the rise of next-generation graphics cards. The be quiet! Pure Power 13 M offers versatile connectivity with a native 12V-2x6 connector for next-gen PCIe 5.1 graphics cards, alongside four PCIe 6+2-pin connectors for current-gen GPUs. This makes it highly adaptable for evolving system requirements. Meanwhile, the NZXT C850 Gold Core also supports next-gen GPUs with its dual-colour 12V-2x6 connector and can accommodate up to three 8-pin PCIe cables. Both units provide robust connectivity, but the be quiet! model’s additional connectors may offer more flexibility for users with multiple high-performance GPUs.

Build Quality and Design

The design and build quality of a power supply can greatly affect its longevity and performance. The be quiet! Pure Power 13 M features a modular design that simplifies cable management, allowing users to eliminate unnecessary cables for a cleaner system layout. This not only improves airflow but also contributes to lower noise and temperatures. The NZXT C850 Gold Core, while also modular, focuses on aesthetic appeal and efficient airflow with its innovative design. Both models prioritise a tidy installation, but the be quiet! model's emphasis on noise reduction and airflow may provide a more functional advantage for those building quiet, high-performance systems.

Performance Under Load

In terms of performance, the be quiet! Pure Power 13 M stands out with its 1000W continuous power capacity, which allows it to handle short spikes in demand effortlessly—up to double its rated power. This feature is particularly beneficial for users running high-end gaming setups or intensive media creation tasks. The NZXT C850 Gold Core, although slightly lower at 850W, still provides stable and efficient power delivery under load, making it suitable for most gaming rigs and general computing needs. However, for those who anticipate pushing their systems to the limit, the added headroom offered by the be quiet! model may prove advantageous.

Warranty and Support

Warranty and support can influence consumer confidence when purchasing a power supply. Specific warranty details were not provided in the product descriptions, but reputable brands like be quiet! and NZXT generally offer solid customer support and warranties that reflect their commitment to quality. Customers often expect warranties that can range from three to ten years, depending on the model and brand. A longer warranty can be indicative of a manufacturer’s confidence in their product’s longevity and reliability. While both brands are well-regarded, prospective buyers should verify warranty specifics before making a decision.

Which should you buy?

Choosing between the be quiet! Pure Power 13 M 1000W Power Supply and the NZXT C850 Gold Core 850W Power Supply ultimately depends on individual needs and priorities. If you require a higher wattage capacity for demanding systems or future-proofing, the be quiet! model at £99.99 offers superior performance and silent operation features. Conversely, if you are looking for a reliable and efficient power supply at a lower price point of £89.99, the NZXT C850 Gold Core provides excellent performance for most users. Your decision should hinge on your specific usage scenarios, system requirements, and budget considerations.
