Dimension comparison
Overview
When it comes to power supplies, two strong contenders are the CORSAIR RM750x Shift and the Redragon RGPS-850W. The CORSAIR model is priced at $79.99, while the Redragon unit costs $124.99, making the CORSAIR about 36% cheaper. Both power supplies offer robust features suitable for modern gaming rigs, but their designs and functionalities cater to different user preferences.
Design and Build Quality
The design of the CORSAIR RM750x Shift is innovative, featuring a side cable interface that promotes easier access and cleaner cable management. Its fully modular connections allow users to attach only the necessary cables, reducing clutter. In contrast, the Redragon RGPS-850W boasts a compact 160mm size that enhances chassis compatibility and simplifies cable management as well. Both power supplies are built with high-quality materials, but the CORSAIR's use of Japanese 105°C-rated electrolytic capacitors suggests a focus on longevity and reliability.
Performance and Efficiency
In terms of efficiency, both the CORSAIR RM750x Shift and the Redragon RGPS-850W are 80 Plus Gold certified, ensuring high energy efficiency, lower noise levels, and cooler case temperatures. The CORSAIR model is particularly noteworthy for its Zero RPM mode, which allows the fan to operate silently under low to medium loads. The Redragon also features a Zero RPM mode, activating the fan only when temperatures reach 60°C. This similarity in performance metrics highlights that both power supplies deliver effective cooling and energy savings.
Modular Connectivity
The CORSAIR RM750x Shift excels with its fully modular micro-fit connectors, designed to connect only the cables needed for the specific system configuration. This feature not only minimizes cable clutter but also simplifies upgrades. The Redragon RGPS-850W is similarly fully modular and includes flat cables that improve airflow and thermal performance. While both power supplies provide excellent modularity, the CORSAIR's side interface might offer a more user-friendly experience for cable management.
Compatibility
The CORSAIR RM750x Shift is compliant with the latest ATX 3.1 and PCIe 5.1 standards, making it suitable for modern graphics cards and gaming setups. Its support for PCIe Gen 5.1 allows it to resist transient power spikes effectively. On the other hand, the Redragon RGPS-850W also supports ATX 3.1 and PCIe 5.1, which makes it compatible with high-performance GPUs, including NVIDIA's latest series. Both power supplies are up to date with current technology, but the CORSAIR's focus on transient power management gives it a slight edge.
Cooling Solutions
The cooling solutions in both power supplies are commendable. The CORSAIR RM750x Shift features a 140mm fluid dynamic bearing fan engineered for high performance and low noise. Its fan curve is specially calculated for optimal operation. The Redragon RGPS-850W, with its RGB fan, also includes a smart ECO mode that keeps the fan off until necessary, ensuring quiet operation during low usage. While both are designed to maintain low noise levels, the CORSAIR’s fan technology may provide superior reliability in the long run.
Warranty and Support
The CORSAIR RM750x Shift comes with a ten-year warranty, underscoring the brand's confidence in its product's durability and reliability. Although the warranty specifics for the Redragon RGPS-850W aren't provided, the use of 100% Japanese capacitors indicates a focus on longevity. A longer warranty can be a significant factor for users looking for peace of mind regarding their investment, making the CORSAIR a more appealing choice in this aspect.
Price Comparison
At $79.99, the CORSAIR RM750x Shift is considerably more affordable than the Redragon RGPS-850W, which retails for $124.99. This price difference of $45 signifies that users can save approximately 36% by choosing the CORSAIR model. Given that both products offer similar performance features, the cost-effectiveness of the CORSAIR might be a deciding factor for many consumers.
Which should you buy?
Ultimately, the choice between the CORSAIR RM750x Shift and the Redragon RGPS-850W depends on individual needs and preferences. The CORSAIR model stands out for its innovative design, superior warranty, and lower price, making it a solid choice for most users. However, the Redragon RGPS-850W offers robust compatibility with modern GPUs and a compact design. If budget and warranty are priorities, the CORSAIR RM750x Shift is the clear winner; but if RGB aesthetics and a compact form factor are more appealing, the Redragon RGPS-850W could be the right pick.
