Overview of the Products
In this comparison, we examine the Arcity 5V 12V 24V Output Switching Power Supply Unit and the NZXT C850 Gold Core Power Supply. The Arcity is priced at $21.98, making it about 78% cheaper than the NZXT, which retails for $99.99. Each power supply caters to different needs and applications, making their features crucial for potential buyers.
Applications and Usage
The Arcity power supply is designed for a variety of applications including video games machines, CCTV systems, and even coffee machines. It offers three adjustable output voltages: 5V, 12V, and 24V, providing versatility for different devices. On the other hand, the NZXT C850 is tailored for high-performance PCs, especially those using modern NVIDIA graphics cards, thanks to its ATX 3.1 certification and PCIe 5.1 compatibility. This makes the NZXT a more suitable option for gamers and professionals who require reliable power for demanding tasks.
Efficiency Ratings
The NZXT C850 boasts an 80 PLUS Gold and Cybenetics Platinum efficiency rating, which ensures it delivers energy-efficient and stable performance. This rating indicates reduced heat generation and lower power consumption even under high loads. In contrast, the Arcity does not provide specific efficiency ratings but focuses on stability and low ripple noise. While the Arcity is adequate for smaller applications, the NZXT is a clear winner for energy efficiency in gaming and professional setups.
Noise Levels
When it comes to noise levels, the NZXT C850 excels with a Cybenetics noise certification for near-silent operation, rated at A++ for its design. It features a fluid dynamic bearing fan that operates quietly, even in high loads, with a Zero RPM mode during light work. The Arcity, while designed for stability and efficient heat dissipation, does not specify noise levels, which could be a concern in quieter environments. For users prioritizing a silent experience, the NZXT is the better choice.
Build Quality and Design
The build quality of the NZXT C850 is underscored by its use of premium 105°C-rated capacitors, ensuring durability and performance longevity. The fully modular design allows users to utilize only the cables they need, contributing to a cleaner setup. Conversely, the Arcity is compact but lacks the premium features found in the NZXT. Its simpler design may suffice for casual users, but those looking for a professional-grade setup will appreciate the NZXT’s superior build quality.
Price Comparison
With the Arcity priced at $21.98 and the NZXT at $99.99, the Arcity is about 78% less expensive. This significant price difference makes the Arcity an attractive option for budget-conscious consumers or those needing a power supply for less demanding applications. However, the price reflects the features and performance; the NZXT's higher cost is justified by its advanced capabilities and efficiency features suitable for high-performance systems.
Safety Features
Both power supplies incorporate essential safety features, but the NZXT C850 offers a more comprehensive suite of protections, including overvoltage, overcurrent, short-circuit, and over-temperature protection. These features ensure safe operation, especially in demanding environments. The Arcity also includes protections such as overvoltage and short-circuit protection, but lacks the extensive safety measures found in the NZXT, making the latter a more secure option for high-end applications.
Which should you buy?
Ultimately, the choice between the Arcity 5V 12V 24V Output Switching Power Supply Unit and the NZXT C850 Gold Core Power Supply depends on your specific needs. If you are looking for an economical solution for basic applications like LED strips or arcade machines, the Arcity at $21.98 is an excellent choice. However, for those needing a reliable power supply for high-performance gaming or professional workloads, the NZXT C850, with its advanced features and robust design at $99.99, is the better investment.
