NZXT C850 Gold Core - 850W ATX 3.1 Power Supply - 80 PLUS Gold - Cybenetics Plat vs CORSAIR RM650e

Overview of the NZXT C850 Gold Core and CORSAIR RM650e

The NZXT C850 Gold Core is priced at £89.99, while the CORSAIR RM650e is slightly more affordable at £79.99. Both power supplies are designed to meet modern demands, ensuring compatibility with the latest hardware and delivering reliable performance. However, their features differ significantly, catering to different user needs.

Power Output and Efficiency

The NZXT C850 Gold Core boasts an impressive 850W power output and is certified with an 80 PLUS Gold rating, providing high energy efficiency. In contrast, the CORSAIR RM650e offers a lower output of 650W but maintains a commendable level of efficiency, also rated at 80 PLUS Gold. While both power supplies offer energy-efficient performance, the NZXT C850 Gold Core is better suited for power-hungry systems or users planning to upgrade their setups in the future.

Modular Design

The modular design of the CORSAIR RM650e allows users to connect only the necessary cables, which can significantly simplify cable management and enhance airflow within the case. The NZXT C850 Gold Core, while offering compatibility with various connectors, does not explicitly mention a fully modular design. Users prioritising ease of installation and tidiness might find the CORSAIR RM650e to be the more appealing option.

Noise Levels

The NZXT C850 Gold Core is designed for near-silent operation, with a Cybenetics noise certification rating of A++ for models like the C850, ensuring noise levels remain below 15 dBA during light workloads. On the other hand, the CORSAIR RM650e features a 120mm fan that is engineered to keep noise levels low, even at full load. While both power supplies are designed for quiet operation, the NZXT C850 Gold Core may offer a slight edge in noise reduction during lighter tasks.

Cooling Solutions

Cooling is critical in maintaining system stability, especially during intense workloads. The NZXT C850 Gold Core utilises a 135mm fluid dynamic bearing fan that operates quietly and efficiently, with a Zero RPM mode during light workloads to further reduce noise. The CORSAIR RM650e employs a 120mm articulating bearing fan, which is also designed to minimise noise. Although both cooling solutions are effective, the NZXT's Zero RPM mode offers a more tailored approach to maintaining silence during less demanding tasks.

Compatibility with Modern Hardware

Both power supplies are Intel ATX 3.1 certified, ensuring compatibility with the latest components, including support for PCIe 5.1. The NZXT C850 Gold Core includes a dual-colour 12V-2x6 connector, specifically designed for next-gen GPUs, making it an excellent choice for users with modern NVIDIA graphics cards. The CORSAIR RM650e, meanwhile, is compatible with a variety of GPUs, utilising both 12V-2x6 and 8-pin PCIe connections. While both units are compatible with current hardware, the NZXT C850 Gold Core’s specific features make it particularly advantageous for high-end system builders.

Build Quality and Reliability

The build quality of both power supplies is commendable, with the NZXT C850 Gold Core featuring Cybenetics Platinum efficiency, which indicates a high level of performance even under demanding loads. The CORSAIR RM650e is built with 105°C rated capacitors, ensuring reliable performance and longevity. While both products are designed for durability, the NZXT's higher efficiency rating may appeal to those seeking superior performance.

Price Comparison

The NZXT C850 Gold Core is priced at £89.99, making it a premium option in the power supply market. In contrast, the CORSAIR RM650e is more budget-friendly at £79.99. This price difference may influence purchasing decisions, especially for users who are looking to balance performance with cost. Those who require a higher wattage or specific features may find the extra cost of the NZXT C850 Gold Core justified, while others might prefer the savings offered by the CORSAIR RM650e.

Which should you buy?

Choosing between the NZXT C850 Gold Core and the CORSAIR RM650e ultimately depends on your specific needs and budget. If you require a higher wattage, near-silent operation, and advanced features for modern GPUs, the NZXT C850 Gold Core is an excellent choice despite its higher price. However, if you are looking for a reliable, fully modular power supply at a lower price point, the CORSAIR RM650e offers great value without compromising on essential features. Consider your system's requirements and your budget to make the best decision for your setup.
