Corsair RM1200x Shift Fully Modular ATX Power vs NZXT C850 Gold Core - 850W ATX 3.1 Power Supply -

Price Comparison

The Corsair RM1200x Shift is priced at $194.99, while the NZXT C850 Gold Core is significantly more affordable at $99.99. This makes the NZXT model about 49% cheaper than the Corsair power supply. For budget-conscious consumers or those looking to build a cost-effective gaming rig, the considerable price difference could be a decisive factor. However, while the NZXT offers a more accessible price point, the Corsair may justify its higher cost with additional power capacity and features tailored for high-performance systems.

Power Output

In terms of power output, the Corsair RM1200x Shift provides a robust 1200W, making it suitable for demanding builds that require substantial power. In contrast, the NZXT C850 Gold Core offers an 850W capacity, which is adequate for most mid-range to high-end gaming setups. The Corsair’s extra power can be essential for users who plan to run multiple GPUs or overclock their components significantly. Thus, while the NZXT is sufficient for many users, the Corsair’s higher wattage may appeal to enthusiasts and those with more power-intensive systems.

Efficiency Ratings

Both power supplies boast impressive efficiency ratings, with the Corsair RM1200x Shift achieving an 80 PLUS Gold certification. The NZXT C850 Gold Core also holds the same 80 PLUS Gold rating, but it additionally carries a Cybenetics Platinum efficiency certification. This dual certification indicates that the NZXT may deliver slightly better efficiency under various loads. Although both models are designed to minimize energy loss and heat generation, the NZXT’s extra efficiency certification might provide a marginal advantage in lower energy consumption during operation.

Modular Design

The modular design of both the Corsair RM1200x Shift and the NZXT C850 Gold Core facilitates cleaner cable management and allows users to connect only the cables they need. The Corsair features fully modular Micro-Fit PSU connectors, which take up less space and make for a neater build. The NZXT also offers a fully modular design with embossed cables, enhancing durability and flexibility for easier routing. Both designs prioritize user convenience; however, the Corsair’s Micro-Fit connectors may offer a slight edge in space-saving benefits.

Cooling Features

Cooling is a critical factor in power supply performance, and both the Corsair and NZXT models include innovative cooling solutions. The Corsair RM1200x Shift features a 140mm fluid dynamic bearing fan that operates in Zero RPM mode during low to medium loads, resulting in near-silent performance. Similarly, the NZXT C850 Gold Core is equipped with a 135mm fluid dynamic bearing fan and also includes a Zero RPM mode for silent operation during light workloads. While both units excel in quiet cooling, the Corsair has a marginally larger fan, which could potentially enhance airflow and cooling efficiency.

Build Quality

Build quality is essential for long-term reliability, and both power supplies utilize high-quality components. The Corsair RM1200x Shift employs 100% 105°C-rated Japanese electrolytic capacitors, which are known for their durability and reliable power delivery. The NZXT C850 Gold Core similarly features premium 105°C-rated capacitors, ensuring stable performance across various loads. Both brands back their products with substantial warranties—Corsair offers a ten-year warranty, while NZXT provides a seven-year warranty. These warranties reflect confidence in their products' build quality and longevity.

Compatibility

The compatibility of a power supply with modern components is crucial for users planning to upgrade their systems. The Corsair RM1200x Shift is Intel ATX 3.1 certified and supports the PCIe Gen 5.1 platform, making it a solid choice for next-generation GPUs. The NZXT C850 Gold Core is also ATX 3.1 certified and features a dual-color 12V-2x6 connector, ensuring compatibility with both AMD and NVIDIA graphics cards. While both power supplies are ready for current and upcoming hardware, the Corsair’s higher wattage and compliance with newer standards may position it better for future-proofing.

Which should you buy?

In conclusion, the choice between the Corsair RM1200x Shift and the NZXT C850 Gold Core ultimately depends on your specific needs and budget. If you require a higher wattage for a demanding system or plan to run multiple GPUs, the Corsair is the superior option despite its higher price of $194.99. Conversely, if you are building a mid-range setup and prefer a more budget-friendly choice, the NZXT at $99.99 provides ample power and efficiency for most users. Each model has its strengths, making them suitable for different types of PC builds.
