Redragon RGPS-850W 80+ Gold 850 Watt Power Supply w/Upgraded ATX 3.1 & PCIe 5.1 vs CORSAIR CX750M

Price Comparison

When evaluating the price, the Redragon RGPS-850W is priced at C$154.99, while the CORSAIR CX750M offers a more budget-friendly option at C$124.99. This represents a significant difference of C$30. The higher cost of the Redragon power supply may be justified by its additional features and higher wattage, but for those on a budget, the CX750M could be an appealing choice without sacrificing essential performance.

Power Output and Efficiency

The Redragon RGPS-850W boasts an impressive 850 watts of power output, making it suitable for high-performance builds, especially with modern GPUs. In contrast, the CORSAIR CX750M provides a maximum of 750 watts. The Redragon’s 80 Plus Gold certification ensures greater energy efficiency and cooler case temperatures, which can contribute to lower energy bills in the long run. The CX750M also meets the ATX 3.1 and PCIe 5.1 standards, but its lower wattage may limit compatibility with the most demanding components.

Build Quality and Reliability

The Redragon RGPS-850W prides itself on its construction, featuring 100% Japanese capacitors designed for superior reliability and durability. This focus on high-quality components suggests a longer lifespan and greater stability under load, which is crucial for gaming and intensive tasks. The CORSAIR CX750M also claims to have durable components, but it does not specify the use of Japanese capacitors. Both products are built to last, but the Redragon may have the edge in terms of high-end reliability.

Cooling Solutions

In terms of cooling, the Redragon RGPS-850W includes a Zero RPM Mode fan that remains off until the temperature exceeds 60℃, allowing for a quieter operation during low loads. This feature is particularly beneficial for those who value a silent PC environment. On the other hand, the CORSAIR CX750M is equipped with a 120mm low-noise fan that operates quietly under low and medium loads, creating a similarly silent experience. Both cooling solutions are effective, but the Redragon's fan control might provide enhanced quietness during idle periods.

Modular Design

The modular design of a power supply can greatly affect cable management and installation ease. The Redragon RGPS-850W has a compact 160mm size that enables better chassis compatibility and facilitates tidy cable management. However, it does not specify whether it features a fully modular design. Conversely, the CORSAIR CX750M is semi-modular, meaning that while the main power cables are fixed, the remaining cables are modular. This design allows users to attach only the cables they need, potentially reducing clutter within the case.

RGB Features

The Redragon RGPS-850W stands out with its RGB capabilities, offering up to 9 modes and 26 selected colours to enhance the aesthetic appeal of a gaming rig. This feature allows users to match their power supply’s lighting with other RGB components for a cohesive look. In contrast, the CORSAIR CX750M does not mention any RGB lighting features, which could be a deciding factor for gamers looking to create a visually striking setup. The Redragon’s RGB functionality may appeal to those who prioritize aesthetics alongside performance.

Compatibility with Modern GPUs

Both power supplies are designed to support the latest generation of GPUs, including Nvidia RTX 40 and 50 series graphics cards. The Redragon RGPS-850W is specifically upgraded to be PCIe 5.1 ready, allowing for a total power excursion of 200% and GPU power excursion of 300%. This means it can comfortably support high-performance graphics cards like the Nvidia 4090 and 4080 series. The CORSAIR CX750M also supports these newer GPUs with native 12V-2x6 cables, eliminating the need for adapters. However, the Redragon’s higher wattage may provide better performance for high-end builds.

Which should you buy?

Ultimately, the choice between the Redragon RGPS-850W and the CORSAIR CX750M depends on your specific needs. If you're looking for higher wattage, RGB features, and potentially superior reliability, the Redragon RGPS-850W may be worth the extra C$30. However, if you are more budget-conscious and still want a quality power supply with good performance for modern builds, the CORSAIR CX750M at C$124.99 is a solid choice. Each power supply has its strengths, making them suitable for different types of users and setups.
