CORSAIR RM850e vs Redragon RGPS-850W 80+ Gold 850 Watt Power Supply w/Upgraded ATX 3.1 & PCIe 5.1

Price Comparison

When it comes to pricing, the Redragon RGPS-850W 80+ Gold is the more budget-friendly option at C$154.99 compared to the CORSAIR RM850e, which is priced at C$184.99. This difference of C$30 may be significant for consumers looking to save on their power supply purchase. Both power supplies offer similar wattage at 850 watts, making them suitable choices for high-performance builds. However, the lower price of the Redragon model could appeal to gamers or builders who want to maximize their budget without sacrificing power capacity.

Efficiency and Certification

Both power supplies boast high efficiency ratings, but the Redragon RGPS-850W takes the lead with its 80 Plus Gold certification. This certification indicates superior energy efficiency, meaning it operates at a higher efficiency level, leading to cooler case temperatures and reduced noise. The CORSAIR RM850e, while also efficient, does not specify an energy certification, which could be a consideration for consumers prioritizing energy savings and performance. Thus, if efficiency is a key factor for you, the Redragon model is the clear winner.

Build Quality and Reliability

In terms of build quality, the Redragon RGPS-850W is equipped with 100% Japanese capacitors, enhancing its reliability and durability. This construction aims for maximum stability, particularly under heavy loads. Conversely, the CORSAIR RM850e features 105°C-rated capacitors, ensuring steady and reliable power delivery. While both power supplies focus on quality, the specific mention of Japanese capacitors in the Redragon model suggests an edge in reliability. Ultimately, both products are designed to deliver dependable performance, but the Redragon model might appeal to those who prioritise long-term durability.

Cooling and Noise Levels

The cooling systems of both models are designed to maintain quiet operation. The Redragon RGPS-850W features a Zero RPM Mode that keeps the fan off until temperatures reach 60°C, promoting silent operation during low-demand situations. In contrast, the CORSAIR RM850e includes a 120mm rifle bearing fan with a specially calculated fan curve to minimise noise, even at full load. Although both power supplies aim for quiet performance, the Redragon’s fan technology may provide a quieter experience during less intensive usage, making it a potentially more appealing choice for noise-sensitive environments.

Compatibility and Future-Proofing

The Redragon RGPS-850W is built to be ATX 3.1 and PCIe 5.1 ready, ensuring compatibility with the latest graphics cards, including high-performance models like the NVIDIA RTX 4090 and 4080 series. This future-proofing aspect allows for significant power excursions, supporting up to 300% for GPUs. The CORSAIR RM850e is also ATX 3.1 certified and supports PCIe 5.1, but it does not specify the same level of power excursion capability. For users planning to invest in cutting-edge components, the Redragon’s enhanced compatibility positions it as a more robust option for future upgrades.

Features and Functionality

The CORSAIR RM850e offers a fully modular design, allowing users to connect only the cables necessary for their specific build, enhancing cable management and airflow. On the other hand, the Redragon RGPS-850W features RGB lighting with up to nine modes and 26 selected colours, providing aesthetic enhancements alongside its performance capabilities. While functionality is important, the choice between a fully modular design for practicality versus RGB features for visual appeal will largely depend on personal preference. The CORSAIR model may be more appealing for those focused on function, while the Redragon model caters to users who value aesthetics in their builds.

Brand Reputation and Support

Corsair has established a strong reputation in the PC component market, known for high-quality products and excellent customer support. The brand's history and trustworthiness provide a level of assurance for consumers. Redragon, while gaining popularity, does not have the same level of recognition in the power supply segment. However, it has built a reputation for providing good value for money. This brand perception may influence buyers, as some may prefer the reliability associated with Corsair over Redragon, despite the latter's competitive pricing and features.

Which should you buy?

Ultimately, the choice between the CORSAIR RM850e and the Redragon RGPS-850W boils down to your specific needs and priorities. If budget constraints are paramount, the Redragon RGPS-850W offers a lower price point with excellent efficiency and future-proofing capabilities. Its RGB features and Zero RPM mode add appealing elements for gamers seeking visual flair. However, if you prioritise a fully modular design, brand reputation, and potentially superior long-term reliability, the CORSAIR RM850e may be worth the extra C$30. Both power supplies are strong contenders in the 850-watt category, so your decision should align with your personal preferences and build requirements.
