Overview of Both Power Supplies

When comparing the MSI MPG A850GS and the Redragon RGPS-850W, the key takeaway is that both power supplies are 850W, fully modular, and 80+ Gold certified, but they offer different features that cater to specific needs. The MSI MPG A850GS is priced at $110.99, while the Redragon RGPS-850W comes in at $124.99, making the MSI option about 11% cheaper.

The MSI MPG A850GS is designed with gamers in mind, showcasing a unique style and expressiveness, while the Redragon RGPS-850W focuses on performance and aesthetics with RGB lighting. Each product has its strengths, which are worth exploring in detail.

Efficiency and Performance

In terms of efficiency, both power supplies are 80 Plus Gold certified, ensuring high energy efficiency and reduced electricity costs. The MSI MPG A850GS leverages an active PFC design and LLC Half Bridge Topology with a DC-DC module, promoting optimal power delivery during operation. Meanwhile, the Redragon RGPS-850W emphasizes cooler case temperatures and less noise thanks to its Zero RPM Mode fan, which only activates when temperatures reach 60℃.

While both units are designed for high-performance systems, the MSI MPG A850GS offers industrial-level protection features like OVP, OCP, OPP, OTP, SCP, and UVP, ensuring comprehensive safety during use. This makes it a solid choice for gamers who prioritize reliability under heavy loads.

Build Quality and Components

Build quality is crucial for power supplies, and both products showcase premium components. The MSI MPG A850GS boasts 100% all Japanese 105°C capacitors, which are known for their longevity and reliability. In contrast, the Redragon RGPS-850W also features 100% Japanese capacitors, emphasizing maximum powering stability and performance.

The choice of capacitors in both power supplies indicates a commitment to durability, but the MSI MPG A850GS's additional industrial protection features may give it an edge in extreme conditions. This aspect is particularly important for gamers who push their hardware to the limits.

Noise Levels

Noise output is an essential factor for many users, and both the MSI MPG A850GS and Redragon RGPS-850W strive for low noise operation. The MSI option's semi-digital design contributes to quieter performance, while the Redragon unit features a smart ECO Low Noise RGB fan that operates in Zero RPM Mode until temperatures rise.

This means that the Redragon RGPS-850W may provide a quieter experience during light workloads, while the MSI MPG A850GS could be more consistent in noise levels during heavy gaming sessions, depending on system demands. Gamers who value a quiet gaming environment may lean towards the Redragon RGPS-850W for its innovative fan design.
