Price Comparison
The Corsair RM1200x Shift is priced at $194.99, while the Redragon RGPS-850W costs $124.99. This makes the Redragon about 36% cheaper than the Corsair power supply. Given the difference in price, budget-conscious consumers might lean towards the Redragon for their builds. However, it's essential to consider what each power supply offers in terms of features and performance, as the price gap may reflect significant differences in quality and capability.
Power Output and Efficiency
The Corsair RM1200x Shift boasts a robust 1200W power output, providing ample power for high-end builds. In contrast, the Redragon RGPS-850W offers 850W. While both power supplies are 80 Plus Gold certified, indicating high energy efficiency, the Corsair's higher wattage may better suit users with multiple graphics cards or power-hungry components. The difference of 350W in output can be a crucial deciding factor for gamers and creators who require extra power headroom.
Modular Design
When it comes to modularity, both the Corsair RM1200x Shift and the Redragon RGPS-850W are fully modular. This feature allows users to connect only the cables they need, reducing cable clutter and improving airflow within the case. The Corsair's innovative side cable interface provides convenient access to connections, which can simplify builds and upgrades. The Redragon, on the other hand, includes flat fully modular cables designed to optimize efficiency and thermal performance. While both designs promote tidy setups, the Corsair's side interface offers a unique advantage in accessibility.
Cooling and Noise Levels
Cooling capabilities and noise levels are critical factors for any power supply. The Corsair RM1200x Shift incorporates a Zero RPM Fan Mode, ensuring that the cooling fan remains off at low to medium loads for near-silent operation. Similarly, the Redragon RGPS-850W features a Zero RPM Mode, activating the fan only when temperatures exceed 60°C. Both power supplies aim to deliver quiet performance, but the Corsair's design specifically targets low-load scenarios for silence, which could be preferable for users seeking a whisper-quiet PC.
Component Quality
In terms of internal components, the Corsair RM1200x Shift uses 100% 105°C-rated Japanese electrolytic capacitors, which enhance reliability and longevity. The Redragon RGPS-850W also touts 100% Japanese capacitors, ensuring great durability and stability. Both power supplies are built with quality components, but Corsair's assurance of performance under higher temperatures may provide an edge for those aiming for long-term reliability, especially in demanding environments.
Compatibility and Future-Proofing
The Corsair RM1200x Shift is Intel ATX 3.1 certified and supports PCIe 5.1, making it compatible with the latest high-performance graphics cards and motherboards. The Redragon RGPS-850W also supports ATX 3.1 and PCIe 5.1, ensuring it can power cutting-edge GPUs, including NVIDIA's RTX 40 series. However, the Corsair's higher wattage and excellent transient power handling may offer better future-proofing for users planning to upgrade their systems. For users focused on maximizing their investment over time, the Corsair may provide greater assurance.
Aesthetic Considerations
Aesthetics can play a substantial role in a power supply's appeal, particularly to gamers and PC builders. The Corsair RM1200x Shift presents a sleek black finish, while the Redragon RGPS-850W features an RGB fan that offers up to 9 modes and 26 colors. If a visually striking build is a priority, the Redragon's RGB options could enhance the overall look of a gaming setup. However, for those preferring subtlety, the Corsair's minimalist design may be more appealing.
Which should you buy?
Choosing between the Corsair RM1200x Shift and the Redragon RGPS-850W ultimately hinges on your specific needs and budget. The Corsair, priced at $194.99, offers superior wattage, innovative cable accessibility, and high-quality components, ideal for those seeking performance and reliability in high-demand situations. In contrast, the Redragon RGPS-850W, at $124.99, presents a more budget-friendly option while still providing excellent features like RGB aesthetics and full modularity. For gamers and creators who need more power and are willing to pay a premium for it, the Corsair is a strong contender. However, if you're looking for a solid power supply that balances performance with cost, the Redragon could be the better choice.
