Overview of the Products

The Auotac 850W Fully Modular Power Supply is priced at $79.99, while the Corsair RM1200x Shift Fully Modular ATX Power Supply costs $194.99, making it about 144% more expensive. Both power supplies are 80 PLUS Gold certified, ensuring high efficiency, but they cater to different segments of the market. The Auotac is designed to be budget-friendly without sacrificing essential features, whereas the Corsair unit targets users looking for advanced functionality and performance.

Efficiency and Certification

Both the Auotac and Corsair power supplies boast an 80 PLUS Gold certification, which guarantees over 90% efficiency at typical loads. This means both units minimize energy waste and save on electricity costs. However, the Auotac model claims a specific efficiency of 92%, while the Corsair does not state an exact figure. This slight edge in efficiency may appeal to users focused on energy costs, although both will perform admirably in terms of efficiency.

Modularity

The Auotac features a fully modular design, allowing users to connect only the cables they need, which reduces clutter and improves airflow within the case. Similarly, the Corsair model is also fully modular and includes Micro-Fit PSU connectors that take up less space. This design philosophy is essential for those building high-performance PCs, as it facilitates easier upgrades and maintenance. Both products excel in this regard, but the unique side interface of the Corsair model provides added convenience for cable management.

Cooling and Noise Levels

The Auotac power supply includes a 140mm RGB low-noise smart fan designed for efficient heat dissipation and quiet operation. The Corsair unit also features a 140mm fan but adds a Zero RPM mode, which allows the fan to turn off entirely at low and medium loads for virtually silent operation. This feature could be a significant advantage for users who prioritize a quiet computing environment. While both fans are designed for low noise, the Corsair’s innovative cooling technology sets it apart.

Component Quality

Both power supplies utilize 105°C-rated Japanese electrolytic capacitors, ensuring long-term reliability and performance stability. The Auotac emphasizes its 100% Japanese-made components for enhanced durability, which aligns with the premium materials used in the Corsair unit. This similarity indicates that both brands are committed to providing high-quality internal components, making them reliable choices for users seeking long-lasting power supplies.

Support for Modern Standards

The Auotac power supply supports ATX 3.1 and PCIe 5.1 standards, making it suitable for the latest high-performance GPU requirements. On the other hand, the Corsair model is also certified for ATX 3.1 and PCIe 5.1 compliance, ensuring it can handle transient power spikes effectively. Both products are future-proofed for modern gaming and workstation builds, although the Corsair's design may offer a slight edge in terms of advanced connectivity options.

Additional Features

The Auotac model comes with a helpful tool kit that includes a PSU tester, cable management comb, and cable ties, making it beginner-friendly. In contrast, the Corsair model focuses on its modern standby compatibility and exceptionally fast wake-from-sleep times, catering to users who value quick access to their systems. While both units offer unique features, the choice depends on whether you prioritize ease of setup or advanced usability enhancements.

Which should you buy?

Choosing between the Auotac 850W Fully Modular Power Supply and the Corsair RM1200x Shift Fully Modular ATX Power Supply ultimately depends on your specific needs and budget. The Auotac is significantly more affordable at $79.99, making it an excellent option for budget-conscious users or casual gamers. In contrast, the Corsair, priced at $194.99, offers advanced features like Zero RPM fan operation and a side interface, which could be worth the investment for those seeking high performance and convenience. If you're looking for reliable power without breaking the bank, the Auotac is the way to go. However, for users willing to invest more for enhanced functionality and quiet operation, the Corsair is a compelling choice.
