Price Comparison
The ARESGAME AGV Series 650W Power Supply is priced at $44.99, making it about 17% cheaper than the Auotac 850W Fully Modular Power Supply, which retails for $79.99. This price difference may appeal to budget-conscious gamers who are looking for a reliable power supply without breaking the bank. While the ARESGAME offers solid performance for its price point, the Auotac’s higher cost reflects additional features and certifications that may justify the investment for those seeking top-tier performance and efficiency.
Power Output and Efficiency
In terms of power output, the Auotac 850W fully modular power supply has a significant advantage with 850 watts compared to the ARESGAME’s 650 watts. While the ARESGAME is 80 PLUS Bronze certified with an efficiency of 85%, the Auotac boasts an impressive 80 PLUS Gold certification, delivering up to 92% efficiency. This means that the Auotac can provide a more effective power transmission to components, making it a better choice for high-performance builds that demand more power and efficiency.
Modular Design
The ARESGAME AGV Series employs a non-modular design, which means all cables are permanently attached. This can lead to cable clutter inside the case and may affect airflow negatively. In contrast, the Auotac features a fully modular design, allowing users to connect only the cables they need. This design not only eliminates cable clutter but also optimizes airflow within the build, improving overall thermal performance, making it a better option for gamers focused on aesthetics and efficiency.
Cooling Solutions
The cooling solutions differ significantly between the two power supplies. The ARESGAME uses a silent 120mm fan which is designed for excellent cooling performance, while the Auotac comes equipped with a 140mm RGB low-noise smart fan. Not only does the Auotac’s fan outperform standard fans in terms of quietness and heat dissipation, but it also features adjustable RGB lighting. This can enhance the visual appeal of a gaming setup, giving the Auotac an edge for users who value aesthetics alongside functionality.
Components and Build Quality
The Auotac power supply is built with high-quality 105°C-rated Japanese capacitors, ensuring maximum stability and reliability, especially under demanding conditions. On the other hand, while the ARESGAME provides a robust design with features like OVP/UVP/OPP/SCP protection, it does not specify the same level of component quality. For gamers who prioritize longevity and stability in their builds, the Auotac’s superior components could justify the higher price.
Warranty and Support
The ARESGAME AGV Series comes with a solid 5-year warranty, providing users with peace of mind regarding its durability and reliability. Conversely, the Auotac offers an even more impressive 10-year limited warranty. This extended warranty not only reflects the manufacturer's confidence in their product’s longevity but also signifies a commitment to customer support, which can be a decisive factor for users investing in a high-end power supply.
Aesthetics and User Experience
When it comes to aesthetics, the Auotac shines with its RGB lighting, giving users the ability to customize their setup with various light styles. This feature caters to gamers who enjoy a visually appealing environment. The ARESGAME, while functional with its sleek black design, lacks such customizable features. Thus, for those who place a high value on aesthetics and personalization in their gaming rigs, the Auotac stands out as the more attractive option.
Which should you buy?
Ultimately, the decision between the ARESGAME AGV Series 650W Power Supply and the Auotac 850W Fully Modular Power Supply hinges on your specific needs and budget. If you are looking for a more budget-friendly option with solid performance, the ARESGAME is a commendable choice at $44.99. However, if you seek higher efficiency, modularity, superior cooling, and a longer warranty, the Auotac, priced at $79.99, may offer better long-term value. Consider what aspects are most important to you in a power supply to make the best choice for your gaming setup.
