Auotac 850W Fully Modular Power Supply, 80+ Gold vs MSI MAG A750GLS PCIE5, Fully Modular Compact

Overview of the Auotac 850W and MSI MAG A750GLS

The Auotac 850W Fully Modular Power Supply is priced at $79.99, while the MSI MAG A750GLS is slightly more expensive at $89.99, making it about 13% pricier. Both units are 80 PLUS Gold certified, ensuring high efficiency in power delivery, but they cater to different power requirements and features.

The Auotac model offers a higher wattage at 850W, making it a suitable choice for users with high-performance components or those planning future upgrades. In contrast, the MSI MAG A750GLS comes in at 750W, which is adequate for most gaming setups but may limit options for users with high-end graphics cards or multiple GPU configurations.

Modular Design and Cable Management

Both power supplies are fully modular, allowing for better cable management and airflow within the PC case. The Auotac utilizes dragon-patterned cables that help reduce clutter and enhance thermal performance. This feature can substantially improve the overall aesthetics and functionality of your build.

On the other hand, the MSI MAG A750GLS also boasts an easy-to-manage cable design with native dual-color 12V-2x6 cables, providing efficient power delivery to modern GPUs. Its compact size facilitates a seamless fit in various cases, further assisting with organization and airflow. The choice between them may come down to personal preference in cable aesthetics and management.

Cooling Solutions

Cooling solutions are critical in ensuring longevity and performance under load. The Auotac features a 140mm RGB low-noise smart fan, designed for quiet operation and effective heat dissipation. The RGB lighting adds a customizable touch, allowing users to match their build's aesthetic.

Conversely, the MSI MAG A750GLS is equipped with a 135mm Fluid-dynamic bearing fan, which also focuses on low noise levels and enhanced durability. While both units prioritize quiet operation, the Auotac’s larger fan may offer slightly better cooling efficiency under heavy loads, making it a potential choice for overclocking enthusiasts.

Compatibility with Modern Standards

Both power supplies support the latest ATX 3.1 and PCIe 5.1 standards, ensuring compatibility with cutting-edge components. The Auotac’s native 12V-2x6 connector is specifically designed for high-performance graphics cards, allowing it to handle transient power excursions effectively.

In comparison, the MSI MAG A750GLS also features native 12V-2x6 connectors, which can deliver up to 600W for PCIe 5.1 GPUs. While both units meet the necessary standards for modern gaming setups, the Auotac's higher wattage may provide additional headroom for future upgrades, making it a more flexible option for power users.

Durability and Reliability

Durability is essential in power supplies, and both models excel in this regard. The Auotac is built with 105°C-rated Japanese capacitors, ensuring high reliability and stability during operation. This quality is crucial for gamers and streamers who demand unwavering performance.

The MSI MAG A750GLS also emphasizes a robust design with an LLC half-bridge and DC-to-DC converter, alongside multiple protection features such as OCP, OTP, and OVP. This level of protection can safeguard your components from potential power surges and failures. While both power supplies are reliable, the Auotac’s higher-rated capacitors may offer an edge in extreme conditions.

Additional Features

In terms of additional features, the Auotac includes a comprehensive toolkit consisting of a PSU tester, cable management comb, and cable ties, making it user-friendly, especially for beginners. This added value can simplify installation and maintenance.

On the other hand, the MSI MAG A750GLS emphasizes a compact design that aids in better cable management and airflow. While it doesn't come with as many extras as the Auotac, the focus on a streamlined design is beneficial for those with space constraints. The differences in additional features may appeal to different user bases depending on their needs and expertise.

Warranty and Support

Warranty coverage can significantly impact the long-term satisfaction with a power supply. The Auotac comes with a 10-year limited warranty, which is impressive and speaks to the manufacturer's confidence in their product’s durability.

Similarly, the MSI MAG A750GLS also offers a 10-year warranty, ensuring that users are protected against manufacturing defects and can rely on the PSU for years to come. Both warranties demonstrate a strong commitment to quality, giving customers peace of mind with their purchase.

Which should you buy?

Choosing between the Auotac 850W and the MSI MAG A750GLS ultimately comes down to your specific needs and future plans. If you require a higher wattage for potential upgrades and appreciate additional accessories for installation, the Auotac at $79.99 is a compelling choice. However, if you prefer a compact design with solid performance and are comfortable with a slightly higher price of $89.99, the MSI MAG A750GLS is a robust option that will support modern gaming needs effectively.
