CORSAIR RM Series , RM650, Fully Modular Power Supply vs Redragon RGPS-850W 80+ Gold

Overview of Power Supplies

The CORSAIR RM Series and Redragon RGPS-850W are both quality power supplies that aim to deliver efficient and reliable performance for PC builds. The CORSAIR RM650 is priced at $138.31, while the Redragon RGPS-850W is about 17% cheaper at $124.99. Each model comes with unique features that cater to different user needs, making them strong contenders in the power supply market.

Modular Design

Both the CORSAIR RM650 and Redragon RGPS-850W boast fully modular designs, allowing users to connect only the cables necessary for their systems. This feature not only simplifies installation but also enhances airflow within the case, reducing clutter. The CORSAIR RM650 emphasizes its fully modular design by highlighting the importance of connecting only essential cables, while the Redragon RGPS-850W takes it a step further with flat fully modular cables that optimize airflow and efficiency. This distinction may appeal to users who prioritize a clean build and efficient thermal management.

Efficiency Ratings

In terms of efficiency, both power supplies carry the 80 Plus Gold certification, which indicates high energy efficiency and reduced heat generation. The CORSAIR RM650 is designed to deliver consistent power with a focus on quiet operation thanks to its zero RPM fan mode. Meanwhile, the Redragon RGPS-850W also features a zero RPM mode that activates only when temperatures exceed 60°C, ensuring quiet operation under light loads. Both units promise to keep system temperatures cooler and enhance overall performance, making either choice a solid investment for energy-conscious users.

Compatibility with Modern Components

The CORSAIR RM650 is equipped with triple EPS12V connectors and four PCIe 8-pin connectors, ensuring compatibility with modern graphics cards and motherboards. This feature is crucial for users looking to upgrade their systems with high-performance components. The Redragon RGPS-850W, on the other hand, is ATX 3.1 and PCIe 5.1 ready, which allows for a significant power excursion, making it ideal for the latest high-performance graphics cards like the NVIDIA 4090 series. This makes the Redragon a slightly more future-proof choice, especially for gamers and enthusiasts planning to use cutting-edge hardware.

Cooling Solutions

Cooling is an important aspect of any power supply, and both the CORSAIR RM650 and Redragon RGPS-850W aim to minimize noise while maintaining optimal temperatures. The CORSAIR model features a 140mm rifle bearing fan with a specially calculated fan curve for reduced noise, even at full load. Conversely, the Redragon RGPS-850W is equipped with a smart ECO low noise RGB fan that not only cools efficiently but also adds an aesthetic element with multiple RGB modes. Users who appreciate customizable lighting may find the Redragon RGPS-850W more appealing due to its RGB features.

Build Quality and Reliability

The build quality of a power supply can significantly influence its longevity and performance. The CORSAIR RM650 is constructed with industrial-grade, 105°C-rated capacitors, which are known for their reliability and electrical performance. Similarly, the Redragon RGPS-850W uses 100% Japanese capacitors, which are also recognized for their stability and durability. Both power supplies offer excellent build quality, but the choice may come down to brand preference and individual experiences with reliability.

Price Comparison

When it comes to pricing, the Redragon RGPS-850W stands out as the more budget-friendly option at $124.99, roughly $13.32 less than the CORSAIR RM650, which retails at $138.31. This price difference may make the Redragon more appealing to those on a tighter budget, especially considering it also offers an 850W capacity compared to the CORSAIR's 650W. This higher wattage could provide better headroom for overclocking and future upgrades, making it a compelling choice for gamers or content creators needing extra power.

Which should you buy?

In summary, your choice between the CORSAIR RM650 and the Redragon RGPS-850W largely depends on your specific needs. If you prioritize brand reliability and a proven track record, the CORSAIR RM650 might be your best bet. However, if you are looking for a cost-effective, high-capacity option with modern features like RGB lighting and ATX 3.1 compatibility, the Redragon RGPS-850W is likely to be the better choice. Both power supplies provide exceptional value, but understanding your personal requirements will guide you to the right decision.
