Auotac 850W Fully Modular Power Supply, 80+ Gold vs GIGABYTE UD750GM PG5 V2 ICE - 750W 80 Plus

Overview of Power Supplies

In the competitive landscape of power supplies, the Auotac 850W Fully Modular Power Supply and the GIGABYTE UD750GM PG5 V2 ICE are two notable contenders. Both are priced at $79.99, but they offer different capacities and certifications that cater to various user needs. The Auotac delivers 850W while the GIGABYTE offers 750W, which can significantly impact performance based on the user's specific hardware requirements.

Performance and Efficiency

When it comes to efficiency, the Auotac boasts an 80 PLUS Gold certification, ensuring about 92% operational efficiency under typical load conditions. In contrast, the GIGABYTE also carries an 80 PLUS Gold certification, which means both power supplies are built for high efficiency. However, the Auotac's higher wattage may provide more headroom for demanding systems, especially when running high-performance components that require more power under load.

Design and Build Quality

The design of both power supplies reflects a commitment to quality. The Auotac features fully modular dragon-patterned cables, which help eliminate cable clutter and improve airflow. This design can enhance overall thermal performance. The GIGABYTE, while also fully modular, emphasizes a streamlined approach with high-quality materials and a smart hydraulic bearing fan. Both options utilize 100% Japanese capacitors, ensuring durability and reliability in power delivery.

Cooling Solutions

Cooling is crucial for maintaining optimal performance, particularly in high-demand environments. The Auotac includes a 140mm low-noise fan that operates in silent mode, outperforming standard 120mm fans in terms of noise and heat dissipation. On the other hand, the GIGABYTE features a 120mm smart hydraulic bearing fan designed to maintain efficient cooling. While both fans are designed to minimize noise, the larger fan in the Auotac may offer better thermal management.

Compatibility

Both power supplies are compliant with the latest standards, which is vital for contemporary builds. The Auotac is ATX 3.1 and PCIe 5.1 ready, making it suitable for the latest graphics cards and high-performance components. Similarly, the GIGABYTE is also ATX 3.1 certified and supports PCIe Gen 5.1 graphics cards. This compatibility ensures that users can confidently integrate either power supply into modern gaming or workstation setups.

Features and Accessories

The Auotac comes with several useful accessories, including a PSU tester, cable management comb, and cable ties, making it beginner-friendly and easy to manage cables. It also offers a unique dual-color 12V-2x6 PCI-E 5.1 cable, which simplifies cable connection verification. The GIGABYTE, while not as extensive in provided accessories, offers a robust build and high-quality materials that focus on performance. The choice here will depend on whether additional accessories are a priority for the user.

Warranty and Support

Warranty and support are critical for any hardware purchase. The Auotac offers a generous 10-year limited warranty, reflecting confidence in its longevity and reliability. Meanwhile, the GIGABYTE does not specify a warranty duration in the provided data, which could be a consideration for users looking for long-term investment protection. A longer warranty can provide peace of mind, particularly for high-performance builds.

Which should you buy?

Choosing between the Auotac 850W Fully Modular Power Supply and the GIGABYTE UD750GM PG5 V2 ICE ultimately depends on your specific needs. The Auotac offers higher wattage, a larger cooling fan, and a longer warranty, making it ideal for users planning to build high-performance systems or gaming rigs. Meanwhile, the GIGABYTE, while slightly lower in wattage, still provides excellent efficiency and quality with its premium components and compact design. If you prioritize capacity and longer warranty, the Auotac may be the better choice; however, for solid performance in a slightly lower power range, the GIGABYTE remains a compelling option.
