CORSAIR CX650M vs Redragon RGPS-850W 80+ Gold 850 Watt Power Supply w/Upgraded ATX 3.1 & PCIe 5.1

Price Comparison

When considering your next power supply, the price difference between the CORSAIR CX650M and the Redragon RGPS-850W is significant. The CORSAIR CX650M is priced at C$109.99, while the Redragon RGPS-850W comes in at C$154.99. This C$45 price gap may influence your decision, especially if you're budget-conscious. The cost reflects not only the wattage but also the features each unit offers. While both power supplies are equipped with the latest ATX 3.1 and PCIe 5.1 standards, the extra wattage and additional features of the Redragon RGPS-850W justify its higher price point.

Wattage and Performance

In terms of wattage, the Redragon RGPS-850W has a clear advantage with its 850 watts, compared to the 650 watts provided by the CORSAIR CX650M. This 200-watt difference means that the Redragon can support more demanding hardware configurations, including high-performance GPUs such as the Nvidia RTX 40-series and 50-series. It also boasts a 200% total power excursion capacity, allowing for greater efficiency under heavy loads. The CORSAIR's 650 watts, while adequate for many setups, may limit users who plan to upgrade to more power-hungry components in the future.

Efficiency Ratings

Both power supplies are designed with efficiency in mind, but they differ in their efficiency ratings. The Redragon RGPS-850W features an 80 Plus Gold certification, which signifies enhanced energy efficiency and reduced noise levels. This certification means the Redragon operates more efficiently than standard power supplies, helping to lower electricity costs over time. In contrast, the CORSAIR CX650M does not explicitly mention an efficiency rating but is designed to provide reliable power. If energy efficiency is a priority, the Redragon's Gold certification makes it the more appealing choice.

Build Quality and Reliability

When it comes to build quality, the Redragon RGPS-850W employs 100% Japanese capacitors, which are known for their durability and reliability. This choice enhances overall performance stability and longevity, particularly for high-demand gaming and esports applications. The CORSAIR CX650M, while also well-built, does not specify the use of high-quality capacitors, leaving some uncertainty regarding its long-term reliability compared to the Redragon. For users seeking a power supply that can withstand prolonged use under heavy loads, the Redragon RGPS-850W may be the better option.

Cooling Systems

Cooling is a critical factor in maintaining optimal performance for computer components, and here both power supplies feature distinct cooling solutions. The Redragon RGPS-850W is equipped with a Zero RPM Mode fan, which operates silently until the temperature reaches 60℃. This feature allows for quieter operation during low and medium loads. In comparison, the CORSAIR CX650M includes a 120mm low-noise fan that runs quietly under similar conditions. While both units strive for silent operation, the Redragon’s smart fan technology might appeal to those who prioritise noise reduction in their builds.

Design and Aesthetics

The design of a power supply can influence not only functionality but also the overall aesthetics of your PC. The Redragon RGPS-850W offers a compact 160mm size, which enhances compatibility in various chassis and aids in cable management. Additionally, it includes up to 9 RGB modes with 26 selected colours, allowing users to customise the lighting to match their system's theme. The CORSAIR CX650M, while semi-modular and designed for efficient cable usage, does not offer the same level of aesthetic customisation. The added visual appeal of the Redragon may attract gamers looking to create a visually striking setup.

Compatibility with Modern Hardware

Both power supplies are designed with modern hardware in mind, featuring ATX 3.1 and PCIe 5.1 compatibility. This modern standard is essential for supporting the latest GPUs, including those from Nvidia’s RTX 40 and 50 series. The Redragon RGPS-850W is particularly noteworthy for its ability to handle a 300% GPU power excursion, making it an excellent choice for high-performance gaming rigs. The CORSAIR CX650M, while capable, provides less headroom for extreme configurations. If you plan to invest in cutting-edge components, the Redragon’s superior specifications might be more suitable.

Which should you buy?

Ultimately, the choice between the CORSAIR CX650M and the Redragon RGPS-850W comes down to your specific needs and budget. The CORSAIR CX650M is a solid option for those needing a reliable power supply at a lower price point, offering decent performance for mid-range systems. However, if you are looking for higher wattage, better efficiency, and enhanced features such as RGB lighting and advanced cooling, the Redragon RGPS-850W stands out as the superior choice. The decision hinges on whether you value the extra power and features of the Redragon enough to justify the higher cost.
