CORSAIR RM Series , RM650, Fully Modular Power Supply vs NZXT C850 Gold Core - 850W ATX 3.1 Power Supply -

Price Comparison

The NZXT C850 Gold Core is priced at $99.99, making it about 28% cheaper than the CORSAIR RM Series, which is available for $138.31. This significant price difference may be a deciding factor for budget-conscious consumers looking for a reliable power supply. While both models offer excellent performance and reliability, the cost savings on the NZXT model can allow users to allocate funds elsewhere in their builds.

Efficiency Ratings

Both the CORSAIR RM Series and the NZXT C850 Gold Core boast impressive efficiency ratings. The CORSAIR model is rated 80 PLUS Gold, ensuring efficient energy use and minimal heat generation. In contrast, the NZXT model not only carries the same 80 PLUS Gold certification but also has a Cybenetics Platinum rating, which signifies even higher efficiency levels. This means the NZXT power supply is likely to perform better under demanding loads, providing stable and efficient power delivery.

Modular Design

When it comes to modularity, both power supplies offer fully modular designs, allowing users to connect only the cables they need for their systems. This feature helps reduce cable clutter and improves airflow within the PC case. However, the NZXT C850 Gold Core includes embossed cables that are designed for easier routing and a cleaner look. This added design consideration may appeal to users who prioritize aesthetics and organization in their builds.

Cooling Performance

Cooling performance is crucial for maintaining system stability, especially during high-load scenarios. The CORSAIR RM Series features a 140mm rifle bearing fan with a specially calculated fan curve to minimize noise, even at full load. It also has a Zero RPM fan mode for silent operation during lighter loads. On the other hand, the NZXT C850 Gold Core employs a 135mm fluid dynamic bearing fan, which is also designed for whisper-quiet operation and includes a Zero RPM mode. Both fans aim for efficiency and noise reduction, but the slight difference in fan size and design may lead to varying performance under specific conditions.

Compatibility with Modern GPUs

The NZXT C850 Gold Core is designed with modern GPUs in mind, featuring an ATX 3.1 certification and a dual-color 12V-2x6 connector, which ensures compatibility with next-gen NVIDIA graphics cards. This forward-thinking design makes it particularly attractive for users looking to future-proof their setups. The CORSAIR RM Series, while also compatible with modern graphics cards through its triple EPS12V connectors and PCIe power connectors, does not specifically highlight support for the latest standards in the same way as the NZXT model.

Build Quality and Components

Both power supplies are built with high-quality components to ensure reliability and performance. The CORSAIR RM Series utilizes industrial-grade, 105°C-rated capacitors, which are known for their durability under heavy use. Similarly, the NZXT C850 Gold Core also features premium 105°C-rated capacitors, reinforcing its commitment to long-lasting performance. While both power supplies are built to withstand a variety of loads, the specific choice of components may impact their longevity and reliability in the long run.

Warranty and Customer Support

The CORSAIR RM Series comes with a ten-year warranty, which reflects the brand's confidence in the product's durability and performance. In contrast, the NZXT C850 Gold Core offers a seven-year warranty. While both warranties provide ample coverage, the additional three years from CORSAIR may provide extra peace of mind for consumers concerned about long-term reliability.

Which should you buy?

Ultimately, the choice between the CORSAIR RM Series and the NZXT C850 Gold Core depends on your specific needs and budget. If you are looking for a power supply that is about 28% cheaper and comes with a high efficiency rating, the NZXT C850 Gold Core is a compelling option. However, if you prioritize warranty length and a slightly larger fan for cooling, the CORSAIR RM Series may be the better choice. Both options provide excellent performance, but your priorities will dictate the best fit for your build.
