SAMA G850 Power Supply - 850W Fully Modular 80 Plus Gold Certified ATX 3.1 & PCI vs HKY 54V Power Supply AC/DC Adapter for Ubiquiti Network Ultra 60W USW-Ultra-60W

Introduction to Power Supplies

When selecting a power supply for your computing needs, two notable contenders are the SAMA G850 Power Supply and the HKY 54V Power Supply. The SAMA G850 is a robust 850W option with a fully modular design, while the HKY model serves as a reliable 60W adapter specifically for Ubiquiti devices. Each power supply caters to different audiences and requirements, making a comparison essential.

Power Output and Efficiency

The SAMA G850 boasts an impressive output of 850W, making it suitable for high-performance gaming rigs and workstations. It achieves an 80 Plus Gold certification, indicating up to 91.15% efficiency at typical load, which significantly reduces energy waste. In contrast, the HKY 54V Power Supply delivers 60W, specifically designed for Ubiquiti networking devices. While the HKY adapter is efficient for its intended purpose, its maximum output is notably lower than that of the SAMA G850. For users needing substantial power for demanding applications, the SAMA clearly stands out.

Compatibility and Design

The SAMA G850 is fully compliant with Intel ATX 3.1 standards and PCIe 5.1, featuring a native 12V-2x6 connector designed for NVIDIA GeForce RTX 50 and 40 series GPUs. Its fully modular cable design enhances airflow and cable management, contributing to cleaner builds. On the other hand, the HKY Power Supply is tailored for compatibility with Ubiquiti Network devices like the USW-Ultra-60W and USW-Lite-8-PoE. It supports a universal input voltage of 100-240VAC, making it versatile for different regions. While the SAMA offers broader compatibility for high-end PCs, the HKY is specialised for networking equipment.

Build Quality and Components

The SAMA G850 is equipped with premium Japanese capacitors, ensuring long life and stability under load. It also features a silent 140mm Fluid Dynamic Bearing fan for efficient cooling and vibration damping. This level of build quality is indicative of a power supply designed for demanding environments. In comparison, the HKY 54V Power Supply is certified with various safety standards, including UKCA and CE, and includes over-voltage and short-circuit protection. While the HKY focuses on safety for its specific use case, the SAMA G850 is built for performance and longevity, making it a more robust choice for high-performance setups.

Price Comparison

The SAMA G850 is priced at £84.99, reflecting its high power output and premium features. The HKY 54V Power Supply, however, is more budget-friendly at £23.99. This significant price difference highlights the targeted markets of both products. Users on a tight budget or those needing a power supply for basic networking tasks may find the HKY to be more appealing. Conversely, gamers and professionals looking for performance and efficiency are likely to prefer the investment in the SAMA G850.

Safety Features

Safety is paramount in power supplies, and both products offer essential protections. The SAMA G850 comes with a complete range of protections, including over-voltage, over-current, and short-circuit protection. This comprehensive safeguarding ensures safe operation in all conditions, making it suitable for high-performance systems. The HKY Power Supply also features over-voltage and over-current protections, ensuring reliability for Ubiquiti equipment. While both supplies offer critical safety measures, the extensive protections in the SAMA G850 may be more reassuring for users with high-value setups.

User Experience and Installation

The SAMA G850’s fully modular design simplifies installation and allows users to only use the cables they need, enhancing airflow and aesthetics in the build. This feature is particularly advantageous for enthusiasts who value clean and efficient setups. In contrast, the HKY Power Supply, being an adapter, is straightforward to use but lacks the flexibility of modular cables. Users of networking devices may appreciate the simplicity of the HKY, but those building custom PCs will likely prefer the enhanced user experience offered by the SAMA G850.

Which should you buy?

Ultimately, the choice between the SAMA G850 Power Supply and the HKY 54V Power Supply depends on your specific needs. If you require a high-output power supply for a gaming rig or workstation with premium efficiency, the SAMA G850 is the clear winner at £84.99. However, if you are looking for a cost-effective solution for powering Ubiquiti networking devices, the HKY Power Supply at £23.99 is an excellent choice. Each product serves its purpose well, catering to different segments of the market effectively.
