Price Comparison
The ASUS TUF Gaming 1200W Gold is priced at $204.99, while the CORSAIR RM850e is significantly cheaper at $94.99, making it about 54% less expensive. This substantial price difference could be a deciding factor for those on a budget or looking for a reliable power supply without the added cost. The higher price of the TUF Gaming PSU may reflect its premium features and higher wattage, but for users with standard needs, the RM850e offers an appealing option at a much lower price point.
Power Output
Power output is a critical factor in choosing a power supply. The ASUS TUF Gaming 1200W Gold boasts a maximum output of 1200 watts, while the CORSAIR RM850e provides up to 850 watts. For users with high-performance systems requiring more power, such as multiple graphics cards or high-end CPUs, the TUF Gaming model is a better fit. However, for most standard gaming setups, the 850 watts of the RM850e will suffice, providing ample power for a variety of components without any risk of underpowering.
Certification and Efficiency
Both power supplies have notable efficiency certifications, but they cater to different standards. The ASUS TUF Gaming 1200W Gold is 80 Plus Gold certified, indicating it operates at high efficiency levels, wasting less energy and producing less heat. The CORSAIR RM850e also offers impressive efficiency, being Cybenetics Gold rated. While both models emphasize efficiency, the TUF Gaming unit's extra wattage paired with its certification may appeal to users who demand the utmost performance and stability, particularly in gaming scenarios.
Build Quality and Components
The ASUS TUF Gaming 1200W Gold claims military-grade certification for its components, which is a testament to its durability and reliability. It features dual ball bearings in its fan, which typically last longer than sleeve bearing designs. In contrast, the CORSAIR RM850e includes 105°C-rated capacitors to ensure steady power delivery. While both units are built with quality in mind, the TUF model emphasizes its military-grade components, suggesting it may be more robust for prolonged use or harsher conditions.
Modularity
Modularity can greatly affect the ease of installation and cable management. Both the ASUS TUF Gaming 1200W Gold and the CORSAIR RM850e are fully modular, allowing users to connect only the cables they need for their specific build. This feature not only simplifies the installation process but also enhances airflow within the case by minimizing excess cables. The convenience of modular design is a strong point for both units, providing flexibility for users who want a clean and efficient setup.
Noise Level
Noise levels are crucial for users looking for a quiet computing experience. The CORSAIR RM850e is designed with a 120mm rifle bearing fan that operates quietly even under full load, making it an excellent choice for noise-sensitive environments. The ASUS TUF Gaming 1200W Gold does not specify its noise levels but mentions features like dual ball bearing fans that generally perform well in terms of noise reduction. For users prioritizing silence, the RM850e's focus on low noise operation could be a significant advantage.
Warranty and Support
Warranty length can be indicative of a manufacturer's confidence in their product. The ASUS TUF Gaming 1200W Gold comes with an impressive 10-year warranty, offering peace of mind for long-term use. Meanwhile, the CORSAIR RM850e is backed by a solid seven-year warranty. The longer warranty period on the TUF model may suggest it is built for longevity and reliability, appealing to users looking for a power supply that will last through multiple builds or upgrades.
Which should you buy?
When weighing the ASUS TUF Gaming 1200W Gold against the CORSAIR RM850e, your choice largely depends on your specific needs. If you require a high-output power supply for a demanding gaming rig and appreciate military-grade components and a long warranty, the ASUS model may be worth the higher price of $204.99. However, for those with standard power needs or who prioritize budget-friendliness, the CORSAIR RM850e at $94.99 offers excellent performance, low noise, and sufficient power for most builds. Ultimately, both power supplies have their strengths, so consider your system's requirements and your budget to make the best decision.
