CORSAIR RM750e vs HKY 54V Power Supply AC/DC Adapter for Ubiquiti Network Ultra 60W USW-Ultra-60W

Overview of the Products

The CORSAIR RM750e and the HKY 54V Power Supply AC/DC Adapter cater to distinct segments of the power supply market. The RM750e is a high-performance, fully modular power supply priced at £81.99, while the HKY adapter is a budget-friendly option at £23.99 designed specifically for Ubiquiti networking devices. This comparison will delve into their features, performance, and suitability for different users.

Design and Build Quality

The CORSAIR RM750e boasts a fully modular design, allowing users to connect only the cables needed for their system, which helps reduce clutter and improve airflow in the case. This feature is particularly beneficial for gamers and PC builders who value aesthetics and efficient cooling. On the other hand, the HKY 54V Power Supply, while not modular, is tailored for specific networking equipment and adheres to multiple safety certifications, including UKCA and CE, ensuring reliable performance for its intended use. Thus, while the RM750e focuses on flexibility and performance in PC builds, the HKY adapter prioritises compatibility and safety for networking devices.

Performance and Efficiency

Performance is a key area where the CORSAIR RM750e excels. It is Intel ATX 3.1 certified, which means it can support the latest hardware standards, including PCIe 5.1. This capability enables it to handle transient power demands from modern GPUs, making it ideal for high-performance gaming rigs. In contrast, the HKY 54V Power Supply delivers a steady output of 54V at 1.1A, amounting to a total of 60W, which is sufficient for powering Ubiquiti network devices. While both products perform well within their scopes, the RM750e is designed for high-demand environments, whereas the HKY adapter serves a more niche, lower power requirement.

Noise Levels

The CORSAIR RM750e is engineered with a 120mm rifle bearing fan that maintains low noise levels, even under full load. This design is particularly advantageous for users who want a silent gaming or working environment. The HKY 54V Power Supply does not specify its noise levels, but as a power adapter meant for networking equipment, it is likely designed to operate quietly within its intended usage context. Therefore, if noise reduction is a priority, the RM750e stands out as the more sophisticated choice.

Compatibility

Compatibility is a significant factor for both products but in different contexts. The CORSAIR RM750e is a universal fit for ATX power supplies, making it compatible with a wide range of motherboards and components. However, the HKY 54V Power Supply is specifically tailored for Ubiquiti networking hardware, including models like the USW-Ultra-60W and USW-Lite-8-PoE. This specificity offers seamless integration for users with compatible devices. Thus, if you are looking for versatility across various PC builds, the RM750e is ideal, while the HKY power supply excels in its designated use with Ubiquiti equipment.

Safety Features

Safety is paramount in power supplies, and both the CORSAIR RM750e and HKY 54V Power Supply include essential protective features. The RM750e utilises 105°C-rated capacitors to ensure reliability and stable power delivery, which is critical for high-performance systems. Meanwhile, the HKY adapter includes multiple safety protections, such as Over Voltage Protection (OVP) and Short Circuit Protection (SCP), providing peace of mind for users concerned about potential electrical hazards. Both power supplies cater to safety but in different operational environments—one for high-performance computing and the other for networking stability.

Price and Value

When considering price, the CORSAIR RM750e is significantly more expensive at £81.99 compared to the HKY 54V Power Supply, which retails for £23.99. This price difference reflects the RM750e's advanced features and higher power output, making it a worthwhile investment for gamers and PC enthusiasts needing robust and reliable power. Conversely, the HKY adapter offers excellent value for users requiring a reliable power source for Ubiquiti networking devices without the need for extensive power requirements. Therefore, the choice of value depends on the user's specific needs—high-performance computing versus network reliability.

Which should you buy?

Ultimately, the decision between the CORSAIR RM750e and the HKY 54V Power Supply hinges on your specific requirements. If you are building a high-performance gaming PC or a workstation that demands reliable and efficient power, the RM750e is the superior choice, offering advanced features and peace of mind with its certifications. However, if you need a cost-effective solution for powering Ubiquiti networking devices, the HKY adapter provides excellent functionality at a fraction of the price. Assess your needs carefully; both products excel in their respective domains, making them valuable choices for different types of users.
