Price Comparison
When it comes to price, the Cooler Master MWE 850 V2 is significantly more budget-friendly at $95.09 compared to the ASUS ROG Thor 1200W Platinum III PSU, which is priced at $432.35. This makes the Cooler Master about 78% cheaper than its competitor. The ASUS model, while more expensive, boasts premium features that may justify its higher price for those seeking top-tier performance. For users on a tighter budget, the Cooler Master offers a solid entry into the 80 PLUS Gold efficiency category without breaking the bank, while the ASUS is aimed at enthusiasts looking for cutting-edge technology and power efficiency.
Power Output and Efficiency
The ASUS ROG Thor 1200W Platinum III delivers a robust 1200W of power, positioning it well above the Cooler Master MWE 850 V2, which provides 850W. This difference of 350W can be crucial for high-performance gaming rigs or workstations that demand more power. The ASUS also boasts an 80 PLUS Platinum certification, ensuring exceptional power efficiency. In contrast, the Cooler Master is rated at 80 PLUS Gold, which, while still efficient, does not reach the peak levels of the ASUS model. For users who require maximum power output with high efficiency, the ASUS is the clear choice.
Features and Technology
The ASUS ROG Thor brings advanced technology to the table, including GaN MOSFETs that offer up to 30% greater efficiency compared to standard MOSFETs. This innovation not only enhances power delivery but also contributes to a cooler operation. Additionally, the ASUS features a GPU-first intelligent voltage stabilizer, which enhances voltage delivery to graphics cards by up to 45%, ensuring smoother gaming performance. Meanwhile, the Cooler Master MWE 850 V2 includes high-temperature resilience and fully modular cables, offering a tidy setup and improved airflow. While both units have valuable features, the ASUS clearly stands out in terms of cutting-edge technology aimed at gamers and power users.
Build Quality and Warranty
In terms of build quality, the ASUS ROG Thor is designed with premium materials, featuring ROG heatsinks and an aluminum enclosure for superior cooling. It also comes with a generous 10-year warranty, indicating the manufacturer's confidence in its durability and longevity. Conversely, the Cooler Master MWE 850 V2, while well-built, does not emphasize premium materials to the same extent and does not specify a warranty period. The enhanced build quality and extended warranty of the ASUS make it a more reliable choice for users who prioritize durability and long-term performance.
Noise Levels
Noise levels are an important consideration for many PC builders. The ASUS ROG Thor features a turbo mode that allows for extended power excursions while maintaining optimal cooling, though its exact noise level is not specified. The Cooler Master MWE 850 V2 addresses noise concerns with its 120mm hydro-dynamic fan, designed for smoother operation and lower RPMs, which translates to quieter performance. For users who are sensitive to noise, the Cooler Master may be more appealing due to its focus on reducing operational sound, whereas the ASUS is likely to produce more noise during high-performance tasks.
Compatibility
In terms of compatibility, the ASUS ROG Thor 1200W Platinum III is ATX 3.1 compliant, ensuring it can work seamlessly with the latest hardware. This makes it a future-proof option for users looking to invest in high-end components. The Cooler Master MWE 850 V2 also supports current generation motherboards with its two EPS connectors, making it versatile for various builds. However, the higher wattage and advanced features of the ASUS make it a better fit for high-performance systems that may require more power in the future.
User Experience and Setup
The ASUS ROG Thor is designed with user experience in mind, featuring a magnetic OLED display that shows real-time power draw and can be positioned based on installation preferences. Its etched modular cables also simplify cable management, promoting a cleaner build. The Cooler Master MWE 850 V2 offers fully modular cables that reduce clutter and enhance airflow, but it lacks the advanced display feature of the ASUS. Users who appreciate real-time feedback and ease of management may find the ASUS considerably more appealing, while those looking for straightforward installation could find satisfaction with the Cooler Master.
Which should you buy?
Ultimately, the decision between the ASUS ROG Thor 1200W Platinum III and the Cooler Master MWE 850 V2 comes down to your specific needs and budget. If you are seeking top-tier performance, advanced technology, and future-proofing capabilities, the ASUS model, despite its higher price of $432.35, is an excellent investment. However, if you are on a budget, the Cooler Master at $95.09 offers solid performance and features for mid-range builds. For users focused on high efficiency and power output, the ASUS is the clear winner, while the Cooler Master serves as a practical option for those looking to save money without sacrificing too much quality.
