Pricing Comparison
The Auotac 850W Fully Modular Power Supply is priced at $79.99, making it about 17% cheaper than the Cooler Master MWE 850 V2 Full Modular PSU, which retails for $95.09. This price difference could be significant for budget-conscious consumers looking to maximize performance per dollar. While both power supplies feature an 80+ Gold certification, the lower price of the Auotac may appeal to those who prioritize cost while still seeking reliable power for their systems.
Efficiency and Certification
Both power supplies hold an 80+ Gold certification, meaning they deliver at least 87% efficiency at 20% and 100% loads, and 90% at 50% load. However, the Auotac boasts a remarkable efficiency of 92%, ensuring effective power transmission to components. This higher efficiency can lead to lower energy costs over time. In contrast, Cooler Master’s MWE 850 V2 has not specified a precise efficiency percentage but is still classified within the same high-performance tier.
Modular Design and Cable Management
The Auotac features a fully modular design with dragon-patterned cables that not only reduce cable clutter but also optimize airflow within the PC case. This can enhance cooling efficiency and overall system performance. On the other hand, the Cooler Master MWE 850 V2 also offers a fully modular setup with flat black cables that serve a similar purpose. While both power supplies excel in cable management, the unique aesthetic of the Auotac's dragon-patterned cables may appeal to users looking for a visually striking setup.
Cooling Solutions
The Auotac is equipped with a 140mm RGB low-noise fan that outperforms standard 120mm fans in terms of quietness, heat dissipation, and durability. This feature can make a significant difference in maintaining an optimal operating temperature. Conversely, the Cooler Master MWE 850 V2 employs a 120mm Hydro Dynamic Bearing (HDB) fan that minimizes friction for quieter operation. Although both fans aim to reduce noise and improve cooling, the larger fan in the Auotac may provide better airflow, especially in high-performance systems.
Compatibility and Connectivity
The Auotac is compliant with the ATX 3.1 standard and supports the PCIe 5.1 platform, making it suitable for modern, high-performance components. It includes a dual-color 16-pin cable designed specifically for high-end graphics cards, enhancing ease of use and installation. In comparison, the Cooler Master MWE 850 V2 also includes two EPS connectors for motherboard compatibility but lacks the same level of specification for next-gen GPU support. This difference may be crucial for users planning to integrate cutting-edge hardware into their builds.
Build Quality and Components
The Auotac utilizes 100% Japanese-made 105°C electrolytic capacitors, ensuring high reliability and durability under intense usage conditions. This premium component choice can lead to longer lifespan and stable performance, especially in high-stress environments like gaming or content creation. Conversely, while the Cooler Master MWE 850 V2 is designed for high temperature resilience with a maximum operating temperature of 50 degrees Celsius, it does not specify the origin or rating of its capacitors. This could impact long-term reliability compared to the Auotac.
Additional Features
The Auotac comes with a comprehensive toolkit, including a PSU tester, cable management comb, and cable ties, making it user-friendly, particularly for beginners. These added features can facilitate easier installation and maintenance. The Cooler Master MWE 850 V2, while designed for ease of use, does not mention any such toolkit or additional accessories, which may be a disadvantage for users seeking complete setup solutions.
Which should you buy?
Choosing between the Auotac 850W Fully Modular Power Supply and the Cooler Master MWE 850 V2 ultimately hinges on your specific needs. If you are looking for a more budget-friendly option with superior efficiency, better cooling capabilities, and a toolkit for easy installation, the Auotac is the clear winner at $79.99. However, if you prefer a tried-and-true brand and are willing to pay a premium for potentially enhanced build quality and support, the Cooler Master MWE 850 V2 could be a suitable choice at $95.09.
