When it comes to power supply units for gaming, two popular options that often come up in discussions are the Corsair RM850x and the Thermaltake Toughpower GF1 850W. Both of these power supplies are high-quality, 80+ Gold certified, and designed to provide reliable and efficient power to demanding gaming systems. In this comparison, we'll delve into the features, specifications, and performance of each unit to help you decide which one is best for your needs.
Efficiency and Certification
Both the Corsair RM850x and Thermaltake Toughpower GF1 850W are 80+ Gold certified, which means they have an efficiency rating of at least 90% at 50% load. This certification ensures that these power supplies waste less energy as heat and provide more power to your components. However, the Corsair RM850x has a slightly higher efficiency rating, with an average efficiency of 91.5% compared to the Thermaltake Toughpower GF1 850W's 90.5%.
Power Output and Rail Configuration
Both power supplies have a maximum output of 850 watts, which is more than enough for most gaming systems. The Corsair RM850x has a single +12V rail configuration, with a maximum current output of 70.8A. In contrast, the Thermaltake Toughpower GF1 850W has a dual +12V rail configuration, with two separate rails providing up to 30A and 40A respectively. While the single-rail design of the Corsair RM850x can provide more flexibility in terms of component selection, the dual-rail design of the Thermaltake Toughpower GF1 850W can provide better stability and reduced voltage ripple.
Connectors and Cabling
The Corsair RM850x has a total of 8 SATA connectors, 4 PCIe connectors, and 2 EPS connectors. In contrast, the Thermaltake Toughpower GF1 850W has 10 SATA connectors, 6 PCIe connectors, and 2 EPS connectors. While both power supplies have plenty of connectors to go around, the Thermaltake Toughpower GF1 850W has a slight advantage in terms of connectivity options.
Cooling and Noise
The Corsair RM850x uses a 135mm rifle-bearing fan, which provides excellent airflow and low noise levels. The fan is also designed to be highly durable and resistant to dust buildup. In contrast, the Thermaltake Toughpower GF1 850W uses a 120mm hydraulic bearing fan, which while still relatively quiet, may not provide the same level of airflow as the Corsair RM850x's larger fan.
Modularity and Build Quality
Both power supplies are fully modular, meaning that you can remove any unnecessary cables to reduce clutter and improve airflow in your system. The build quality of both units is also excellent, with high-quality components and a sturdy construction. However, the Corsair RM850x has a slightly more premium feel to it, with a sleeker design and higher-quality connectors.
Warranty and Support
Both Corsair and Thermaltake are well-known for their excellent customer support and warranty programs. The Corsair RM850x comes with a 10-year warranty, while the Thermaltake Toughpower GF1 850W has a 10-year warranty as well. Both companies also offer excellent online resources and technical support in case you encounter any issues with your power supply.
Conclusion
In conclusion, both the Corsair RM850x and Thermaltake Toughpower GF1 850W are high-quality power supply units for gaming that can provide reliable and efficient power to demanding systems. While both units have their strengths and weaknesses, the Corsair RM850x has a slight edge in terms of efficiency, build quality, and cooling performance. However, the Thermaltake Toughpower GF1 850W has a more flexible rail configuration and more connectivity options, making it a great choice for users with multiple GPUs or other power-hungry components.
Ultimately, the decision between these two power supplies will depend on your specific needs and preferences. If you prioritize efficiency, build quality, and low noise levels, the Corsair RM850x may be the better choice. However, if you need more flexibility in terms of component selection and connectivity options, the Thermaltake Toughpower GF1 850W is definitely worth considering.
