Auotac 850W Fully Modular Power Supply, 80+ Gold vs Cooler Master V850 SFX Gold 850W Fully Modular

Price Comparison

The Auotac 850W Fully Modular Power Supply is priced at $79.99, making it about 48% cheaper than the Cooler Master V850 SFX Gold, which retails for $153.25. This significant price difference may appeal to budget-conscious consumers looking for a reliable power supply without breaking the bank. While the Auotac offers excellent features for its price, the Cooler Master is positioned as a premium option with additional benefits that may justify its higher cost for certain users.

Design and Form Factor

The Auotac power supply features a standard ATX form factor, which provides compatibility with a wide range of cases. In contrast, the Cooler Master V850 SFX Gold is designed for small form factor (SFF) builds, making it ideal for mini-ITX cases. The compact design of the Cooler Master allows for more versatile placement in tighter spaces, while the Auotac's larger size may be better suited for traditional builds. The choice between these two ultimately depends on the specific requirements of your system.

Efficiency Ratings

Both power supplies boast an 80 PLUS Gold certification, which indicates high efficiency in power delivery. The Auotac achieves 92% efficiency, while the Cooler Master offers slightly lower efficiency at 90%. Despite this minor difference, both models excel in reducing energy waste, which is beneficial for users concerned about power consumption and utility bills. The efficiency ratings of both units ensure that they can effectively power high-performance components while minimizing heat generation.

Cooling Solutions

The Auotac features a 140mm RGB low-noise smart fan that provides effective cooling while maintaining a quiet operation. This is a notable advantage for users who prioritize a silent PC environment. Conversely, the Cooler Master V850 SFX Gold is equipped with a 92mm Fluid Dynamic Bearing (FDB) fan, known for its reliability and low maintenance. While both fans aim to enhance cooling, the larger fan of the Auotac may offer better heat dissipation due to its size, providing an edge in thermal performance.

Cable Management

The Auotac comes with fully modular cables that help eliminate clutter and optimize airflow within your PC case. This feature enhances the overall aesthetic and efficiency of the build. The Cooler Master also offers fully modular connectivity but includes 90° angled cables for improved electrical durability and safety. While both power supplies provide excellent cable management solutions, the unique angled design of the Cooler Master's cables may be preferable for specific setups, particularly in tight spaces.

Component Quality

The Auotac power supply utilizes 100% Japanese-made 105°C capacitors, ensuring high reliability and durability. This is a crucial aspect for gamers and professionals who require stable performance during demanding tasks. The Cooler Master similarly employs high-quality 100% Japanese capacitors, enhancing its efficiency and reducing ripple noise. Both units promise long-lasting performance, but the emphasis on capacitor quality in both models highlights their commitment to reliability, making either choice a solid investment.

Warranty and Support

The Auotac comes with a generous 10-year limited warranty, which reflects the manufacturer's confidence in the product’s durability and performance. This warranty can provide peace of mind for users investing in a power supply. The Cooler Master also matches this with its own 10-year warranty, further emphasizing its reliability. Both warranties are beneficial, but they may also reflect the manufacturers' commitment to customer service and long-term support.

Which should you buy?

Choosing between the Auotac 850W Fully Modular Power Supply and the Cooler Master V850 SFX Gold ultimately boils down to your specific needs and budget. The Auotac is a compelling choice for those looking for an affordable yet efficient power supply, offering a great balance of performance and cost at $79.99. On the other hand, the Cooler Master, while more expensive at $153.25, caters to users with small form factor builds who may benefit from its compact design and premium features. If price is your main concern, the Auotac is the clear winner; however, if you seek a high-quality, space-efficient solution, the Cooler Master may justify its higher price point.
