Price Comparison
The Apevia ITX-PFC500W is priced at $49.99, while the Auotac 850W comes in at $79.99, making the Apevia about 37% cheaper. This significant price difference may appeal to budget-conscious consumers who need a reliable power supply without breaking the bank. While the lower price of the Apevia does not reflect its capabilities as a Mini ITX/Flex ATX power supply, the Auotac offers higher wattage and additional features, which could justify its cost for those seeking performance and longevity.
Power Output
The Auotac 850W delivers a maximum power output of 850W, which is significantly higher than the 500W offered by the Apevia ITX-PFC500W. This 70% increase in power means that the Auotac is better suited for high-performance builds, particularly those requiring more power for demanding components like graphics cards. The Apevia, however, caters to smaller systems and may be ideal for compact setups or budget builds that do not require extensive power.
Certification and Efficiency
Efficiency is a crucial factor in power supply selection, and here the Auotac shines with its 80+ Gold certification, boasting 92% efficiency. This means that it will waste less power and produce less heat compared to the Apevia, which does not have a certification rating mentioned. Higher efficiency not only saves on electricity bills over time but also contributes to better thermal performance, making the Auotac a more reliable choice for long-term use.
Modular Design
Both the Apevia ITX-PFC500W and the Auotac 850W feature fully modular designs, allowing users to connect only the cables they need. This reduces cable clutter, enhancing airflow and aesthetics in a PC build. The Apevia includes standard connectors suited for Mini ITX and Flex ATX systems, while the Auotac leverages modern dragon-patterned cables that are designed for high-performance setups. This modularity is essential for gamers and creators who prioritize airflow and system cleanliness.
Cooling Solutions
The cooling capabilities of both power supplies are noteworthy. The Apevia uses a 40mm double ball bearing fan for forced air ventilation, which is adequate for its size and power output. In contrast, the Auotac employs a larger 140mm low-noise smart fan, which provides superior cooling and quieter operation. The enhanced cooling solution of the Auotac can lead to improved longevity and stability, especially in high-performance scenarios where heat management is critical.
Additional Features
The Auotac 850W includes several additional features that enhance its value, such as a dual-color 16-pin cable for easy connection verification, RGB lighting for customizability, and a toolkit that includes a PSU tester and cable management tools. These features not only add to the user experience but also cater to gamers and PC enthusiasts who appreciate aesthetics and functionality. The Apevia lacks such additional features, focusing instead on the essentials for small form factor builds.
Warranty and Reliability
When it comes to warranty, the Auotac 850W offers a 10-year limited warranty, underscoring its reliability and the manufacturer's confidence in its product. The Apevia does not specify a warranty period, which may raise concerns regarding its long-term reliability. For users looking for peace of mind and assurance in their investment, the extended warranty from Auotac could be a significant deciding factor.
Which should you buy?
Ultimately, the choice between the Apevia ITX-PFC500W and the Auotac 850W will depend on your specific needs and budget. If you are building a compact system with lower power requirements, the Apevia may be the ideal choice due to its lower price and sufficient power output. However, for those who need more power, efficiency, and additional features, the Auotac stands out despite its higher price. Consider your current and future hardware requirements carefully before making your decision.
