Corsair RM850x 850W 80 Gold Certified Fully Modular ATX Power Supply

The Corsair RM850x 850W power supply is a high-performance, efficient, and quiet solution for powering your modern PC systems. This fully modular ATX design offers the flexibility to only connect the cables you need, reducing clutter and improving airflow within your case.

Corsair's RM850x power supply is 80 Gold certified, ensuring an impressive efficiency of up to 90% under typical loads. With a single 12V rail and a continuous output of 71.4A, this power supply provides ample power headroom for high-end systems and components.

One of the most notable features of the RM850x is its Zero RPM fan mode. This innovative technology allows the fan to remain off at low to medium loads, resulting in virtually silent operation. When the system demands more power, the fan automatically starts up to maintain optimal temperatures, ensuring reliable and stable operation.

The RM850x comes with a comprehensive set of cables, including 1 x 24-pin ATX, 1 x 4 4-pin EPS12V, and 12 x PCIe cables, to support a wide range of modern components and configurations. The fully modular design allows you to only connect the cables you need, making installation easier and reducing potential cable management issues.

Corsair's commitment to quality and reliability is evident in the RM850x's robust build and excellent components. The unit features a 105 C Japanese Capacitors, ensuring long-lasting performance and stability. Additionally, Corsair covers the RM850x with a 10-year warranty, offering peace of mind for PC builders and enthusiasts.

With its impressive power output, quiet operation, flexibility, and robust build, the Corsair RM850x 850W power supply is an excellent choice for powering modern and high-performance PC systems.

The Corsair RM850x (RP-ATX-850-RD) and Corsair RM850x (RP-ATX-850-BL) are high-performance, 850-watt, fully modular power supplies (PSUs) designed for use in modern PC systems. Both models share many similarities, but there are also some key differences that could influence your purchasing decision.

Common Features:

1. 80 Gold certification for high efficiency.

2. Fully modular design for improved cable management.

3. Zero RPM fan mode for silent operation at low loads.

4. High-quality Japanese capacitors for reliability.

5. Overvoltage, overcurrent, and short circuit protection.

Differences:

1. Aesthetics: RP-ATX-850-RD comes with a matte black finish, while RP-ATX-850-BL features a fully black finish with white Corsair logo.

2. Price: The matte black model (RP-ATX-850-RD) tends to be slightly cheaper than the fully black model (RP-ATX-850-BL).

Pros of Corsair RM850x:

1. High-performance: Delivers a consistent 850 watts of power for efficient and stable system operation.

2. Fully modular: Allows for custom cable configurations, reducing clutter and improving airflow.

3. Silent operation: Zero RPM fan mode ensures quiet operation when the system is under low load.

4. Reliable: High-quality components and advanced protection features ensure long-term durability and reliability.

Cons of Corsair RM850x:

1. Price: The Corsair RM850x is a premium power supply, so it comes at a higher cost compared to some other power supplies in its class.

2. Size: At 150mm (depth), it may not fit in smaller cases, especially those with limited clearance for the power supply.

Conclusion:

If you're looking for a high-performance, fully modular, and reliable power supply for your PC, the Corsair RM850x (RP-ATX-850-RD or RP-ATX-850-BL) should be on your shortlist. Its advanced features, like zero RPM fan mode, silent operation, and high-quality components, make it an excellent choice for any modern system. However, its premium price and size may be limiting factors for some users. Ultimately, if aesthetics are a priority and you're willing to pay a little more, the fully black model (RP-ATX-850-BL) would be the better option. If you're more concerned about cost, the matte black model (RP-ATX-850-RD) offers similar performance at a slightly lower price.

Recommendation:

Based on the pros and cons, I would recommend the Corsair RM850x (RP-ATX-850-RD) for most users due to its competitive price and excellent performance. However, if you're looking for a power supply with a fully black finish, the Corsair RM850x (RP-ATX-850-BL) is a worthy alternative. Both power supplies offer impressive features and are sure to meet the needs of most modern systems.
