Price Comparison
When it comes to pricing, the Apevia ITX-PFC500W is significantly cheaper than the NZXT C850 Gold Core, making it about 50% less expensive at $49.99 compared to the NZXT's price of $99.99. For budget-conscious consumers, this price point marks a substantial difference, especially considering the capabilities of each power supply. While the Apevia offers a maximum power output of 500W, the NZXT doubles that with 850W, which may justify its higher price for users who need more power for demanding systems.
Power Output
The power output is a crucial factor to consider when comparing the two products. The NZXT C850 Gold Core boasts an impressive 850W capacity, which is 70% more than the 500W provided by the Apevia ITX-PFC500W. This higher output is particularly beneficial for gamers and professionals using high-performance components, such as modern NVIDIA graphics cards, which often require more power. Consumers needing a robust power supply for their setups may find the NZXT's higher wattage to be essential.
Efficiency Ratings
In terms of efficiency, the NZXT C850 Gold Core stands out with its 80 PLUS Gold certification and Cybenetics Platinum rating. This ensures that it delivers stable performance while minimizing energy loss. The Apevia ITX-PFC500W does not have such efficiency certifications listed, which may indicate that it is not as optimized for energy use. This difference is significant for environmentally conscious consumers or those looking to reduce their electricity bills, as the NZXT's efficiency can lead to long-term savings.
Modular Design
Modular design is another area where these two power supplies differ. The Apevia ITX-PFC500W is fully modular, allowing users to connect only the cables they need, which helps in managing cable clutter. The NZXT C850 Gold Core also features a fully modular design, but it includes embossed cables that add a touch of aesthetic appeal and ease of use. Both designs enhance the installation experience, but the NZXT's additional features may attract users looking for a more polished look in their builds.
Cooling Mechanism
Cooling is essential for maintaining performance and longevity in power supplies. The Apevia ITX-PFC500W utilizes a 40mm double ball bearing fan for forced air ventilation, which is adequate for its size and power output. However, the NZXT C850 Gold Core employs a larger 135mm fluid dynamic bearing fan that operates quietly and features a Zero RPM mode during light workloads, ensuring minimal noise. This makes the NZXT more suitable for users who prioritize a quiet computing experience, particularly in home or office environments.
Compatibility with Modern Components
When it comes to compatibility, the NZXT C850 Gold Core is designed with next-generation GPUs in mind, featuring a dual-color 12V-2x6 connector that supports both AMD and NVIDIA graphics cards. This compatibility is crucial for users planning to upgrade their systems with the latest hardware. The Apevia ITX-PFC500W, while versatile, is primarily geared toward standard Mini-ITX and Flex ATX setups and may not support the latest high-performance components as effectively as the NZXT.
Warranty and Reliability
The reliability of a power supply is often reflected in its warranty. The NZXT C850 Gold Core comes with a 7-year warranty, a strong indicator of its durability and the manufacturer's confidence in its product. In contrast, the warranty information for the Apevia ITX-PFC500W is not mentioned, which may raise questions about its long-term reliability. Consumers looking for peace of mind with their purchase may prefer the NZXT due to its extended warranty period.
Which should you buy?
Choosing between the Apevia ITX-PFC500W and the NZXT C850 Gold Core largely depends on your specific needs. If you're on a tight budget and require a basic power supply for a small form factor system, the Apevia offers a cost-effective solution at $49.99 with adequate features for standard builds. However, if you seek higher power output, efficiency, and enhanced compatibility with modern components, the NZXT C850 Gold Core is worth the investment at $99.99. Its superior features, warranty, and quieter operation make it a compelling choice for gamers and power users alike.
