JUSTOP Black 750W PSU vs 5V Power Supply for Polycom VVX 150 250 350 450 2200-48872-001 1465-48871-001

Overview of the Products

The JUSTOP Black 750W PSU and the 5V Power Supply for Polycom are designed for entirely different applications, catering to distinct user needs. The JUSTOP Black 750W PSU is aimed at desktop PC users requiring a robust power supply, while the 5V Power Supply for Polycom is specifically tailored for VoIP phones.

The JUSTOP PSU is priced at £32.95, offering a powerful 750W output, whereas the 5V Power Supply is significantly more affordable at £11.98, providing a modest 15W output. This price disparity reflects their capabilities and intended use cases, making them suitable for different audiences.

Power Output Comparison

In terms of power output, the JUSTOP Black 750W PSU stands out with its impressive 750W capability, making it suitable for high-performance desktop PCs. This power supply features a single 8-pin (4+4 pin) 12V rail, which enhances stability and ensures a safer power output.

Conversely, the 5V Power Supply for Polycom offers a much lower output of 15W, specifically designed for powering VoIP phones like the Polycom VVX series. It delivers 5V DC at 3A, which is adequate for the phone's requirements but would be insufficient for any desktop computing needs. Therefore, if high power is essential, the JUSTOP PSU is the superior choice.

Compatibility and Use Cases

The JUSTOP Black 750W PSU is designed for general desktop PC use and is compatible with a wide range of components. It includes connectors for a typical setup: one 24-pin (20+4) connector, one 8-pin 12V connector, and multiple SATA and Molex connectors, providing flexibility for various builds.

In contrast, the 5V Power Supply for Polycom is highly specialised, offering compatibility with specific VoIP phone models. It works with Polycom VVX 150, 250, and 350, among others, and is also compatible with certain Cisco and Yealink models. If you are looking for a power supply for a desktop PC, the JUSTOP is the clear winner, while the 5V Power Supply excels in VoIP applications.

Safety Features

Safety is a critical aspect of power supplies, and the JUSTOP Black 750W PSU includes a variety of protective features. It has over voltage protection, over power protection, short circuit protection, and thermal overload cut-off protection, ensuring a safe operating environment for connected components.

The 5V Power Supply for Polycom, while not as feature-rich in terms of safety protocols, is designed to meet the basic safety standards for powering VoIP phones. However, it does not specify any advanced protective features, making the JUSTOP PSU the safer option for users concerned about component protection and reliability.

Design and Cooling

The design of the JUSTOP Black 750W PSU includes a 120mm cooling fan, ensuring optimal thermal management and increased longevity of the unit. This cooling solution is essential for maintaining performance under load, particularly in demanding desktop environments.

On the other hand, the 5V Power Supply for Polycom does not mention any cooling features, which is typical for power supplies designed for low-power applications. As such, the JUSTOP PSU's design is more robust, catering to users who require efficient cooling for high-performance systems, while the Polycom power supply is simpler and more compact, suited for stationary VoIP setups.

Price Consideration

When evaluating price, the JUSTOP Black 750W PSU is priced at £32.95, reflecting its high output and extensive features. This investment is justified for users who need a powerful and reliable power supply for gaming or workstation PCs.

In contrast, the 5V Power Supply for Polycom is priced at a mere £11.98, making it an economical choice for those solely focused on powering VoIP phones. The significant price difference indicates that while the JUSTOP PSU caters to a more demanding audience, the Polycom power supply is perfect for budget-conscious consumers needing a basic power solution.

Brand Reputation and Support

JUSTOP is known for producing reliable power supplies that meet various safety certifications, including UKCA, CE, FCC, UL, and TUV, which adds to the trustworthiness of the product. Customers can expect a degree of reliability and support from a brand that prioritises safety and performance.

On the other hand, COLM, the brand behind the 5V Power Supply for Polycom, is less well-known in the broader power supply market. While they provide a compatible power solution for specific phone models, the brand may not have the same level of recognition or trust among consumers as JUSTOP. This could influence a buyer's decision, particularly for those prioritising brand reputation.

Which should you buy?

Choosing between the JUSTOP Black 750W PSU and the 5V Power Supply for Polycom ultimately depends on your specific needs. If you are a gamer or someone who builds high-performance PCs, the JUSTOP PSU offers superior power, safety features, and compatibility with multiple components for £32.95. However, if you only need a power supply for VoIP phones and are looking for a budget-friendly option, the 5V Power Supply for Polycom at £11.98 serves that purpose well. In summary, assess your requirements carefully to make the most informed decision.
