NZXT C850 Gold ATX 3.1 - Fully Modular Low-Noise PC Gaming Power Supply - 850 Wa vs CORSAIR RM650e

Overview of the NZXT C850 Gold and CORSAIR RM650e

The NZXT C850 Gold and the CORSAIR RM650e are both exceptional power supplies designed for gamers and high-performance PC users. Priced at £84.90 and £79.99 respectively, these power supplies offer features that cater to modern computing needs. The NZXT C850 Gold boasts an 850W output, while the CORSAIR RM650e provides a slightly lower 650W, making the former a better option for users requiring more power for demanding setups, especially when considering the latest graphics cards.

Power Output and Efficiency

When it comes to power output, the NZXT C850 Gold outshines the CORSAIR RM650e with its robust 850W capability, compared to the RM650e's 650W. This additional wattage allows for greater flexibility in powering components, especially for those with high-end graphics cards. Both power supplies meet the ATX 3.1 standard, ensuring efficiency and stability, but the NZXT's higher output makes it more suitable for future-proofing your gaming rig. The CORSAIR RM650e, while slightly less powerful, still maintains a reliable performance with Cybenetics Gold efficiency, making it an efficient choice for moderately powered systems.

Noise Levels and Cooling

Noise levels can significantly impact the gaming experience, and both power supplies are engineered to operate quietly under load. The NZXT C850 Gold features a 135mm fluid dynamic bearing fan that remains silent under 50% load, a great advantage for users seeking a noise-free environment. In contrast, the CORSAIR RM650e utilises a 120mm fan designed with a calculated curve to keep noise levels low even at full load. While both units prioritise quiet operation, the NZXT’s Zero Fan Mode could be more appealing for those who value absolute silence during lighter usage.

Build Quality and Durability

When evaluating build quality, both power supplies utilise high-grade components to ensure longevity and reliability. The NZXT C850 Gold is equipped with 100% premium Japanese capacitors that enhance hold-up time and reduce ripple noise, promoting stable power delivery. On the other hand, the CORSAIR RM650e features 105°C rated capacitors, which also contribute to its reliable electrical performance. While both units are designed with high-quality materials, the NZXT’s focus on premium capacitors may provide a slight edge in durability.

Modular Design and Cable Management

Cable management is a critical aspect of any PC build, and both the NZXT C850 Gold and the CORSAIR RM650e offer fully modular designs. This feature allows users to connect only the cables required for their specific setup, reducing clutter and improving airflow within the case. The NZXT C850 Gold includes a durable, heat-resistant 12V-2x6 connector that is particularly beneficial for powering NVIDIA GeForce RTX 50 Series graphics cards, enhancing its future-proofing capabilities. Meanwhile, the CORSAIR RM650e’s modular cables also facilitate easy installations and upgrades, making both units user-friendly for builders of all experience levels.

Compatibility and Future-Proofing

Compatibility with modern components is crucial, and both power supplies excel in this regard. The NZXT C850 Gold is designed to support the latest high-performance components, while the CORSAIR RM650e meets the ATX 3.1 power standard and includes support for PCIe 5.1. This ensures that both power supplies are capable of handling the demands of contemporary gaming setups. However, the NZXT’s higher wattage and its specific readiness for NVIDIA’s latest graphics cards make it a more future-proof choice for enthusiasts planning to upgrade their systems in the near future.

Warranty and Support

Warranty and customer support can greatly influence a purchasing decision. The NZXT C850 Gold does not specify its warranty details in the provided information, leaving some uncertainty about long-term support. In contrast, the CORSAIR RM650e comes with a seven-year warranty, which is indicative of the brand’s confidence in their product’s durability and reliability. This extended warranty could provide peace of mind for consumers worried about potential failures down the line.

Which should you buy?

Choosing between the NZXT C850 Gold and the CORSAIR RM650e ultimately depends on your specific needs and future plans. If you require a power supply capable of supporting high-demand components and appreciate features like ultra-low noise operation, the NZXT C850 Gold’s 850W output and premium build quality make it a compelling choice. However, if you are looking for a more budget-friendly option with solid efficiency and a longer warranty, the CORSAIR RM650e at £79.99 may be more appealing. Both are excellent power supplies, but the final decision hinges on your individual requirements and aspirations for your gaming rig.
