JUSTOP Black 750W PSU vs iUniker GaN PD 27W 5.1V 5A 27W PD Power Supply USB-C for Raspberry Pi 5

Price Comparison

When it comes to pricing, the JUSTOP Black 750W PSU is significantly more expensive than the iUniker GaN PD 27W power supply. The JUSTOP model is priced at £32.95, while the iUniker option is much more affordable at £13.79. This represents a difference of £19.16, making the iUniker a budget-friendly option for those looking for a power supply. While the higher price of the JUSTOP PSU might be justified by its higher wattage and additional features, the iUniker's price point makes it an attractive choice for users with less demanding power requirements, particularly those using devices like the Raspberry Pi 5.

Power Output and Suitability

Power output is a critical factor when choosing a power supply. The JUSTOP Black 750W PSU delivers a robust 750W, making it suitable for high-performance desktop PCs that require substantial power for multiple components. In contrast, the iUniker GaN PD 27W power supply provides an output of 27W, which is adequate for devices such as the Raspberry Pi 5. This stark contrast in power output demonstrates that the JUSTOP is designed for more intensive computing tasks, whereas the iUniker is tailored for lower-power applications. Users must consider their specific power needs when choosing between these two options.

Features and Technology

In terms of features, both power supplies offer distinct advantages. The JUSTOP Black 750W PSU includes advanced safety features like over voltage, over power, short circuit, and thermal overload protection. It also has a Power Factor Control (PFC) for efficient energy use. Meanwhile, the iUniker GaN PD 27W power supply boasts GaN technology, which allows it to be compact while maintaining power efficiency. This technology also ensures that it operates at lower temperatures, enhancing its reliability. Users who prioritise advanced safety features may lean towards the JUSTOP, while those seeking a modern, compact solution might prefer the iUniker.

Compatibility

Compatibility is another essential aspect to consider when selecting a power supply. The JUSTOP Black 750W PSU is designed for desktop PCs, featuring multiple connectors including a 24-pin, an 8-pin 12V, and several SATA and PCI-E connectors. This versatility makes it suitable for a wide range of desktop builds. On the other hand, the iUniker GaN PD 27W power supply is specifically compatible with the Raspberry Pi 5, making it an ideal choice for users of this particular device. The specific targeting of each product highlights the need for users to select a power supply that aligns with their hardware requirements.

Size and Form Factor

Size and form factor can impact both installation and portability. The JUSTOP Black 750W PSU, being a standard ATX power supply, is designed to fit within typical computer cases, but it may not be the most compact option available. In contrast, the iUniker GaN PD 27W power supply is a smaller, more portable solution, thanks to its GaN technology, which allows for a reduced footprint without compromising on power delivery. Users who require a power supply for a mobile setup or limited space may find the iUniker to be a more convenient choice, while those building a stationary desktop system may opt for the larger JUSTOP PSU.

Protection Features

Both power supplies offer important protection features, but they cater to different requirements. The JUSTOP Black 750W PSU includes multiple safety certifications such as UKCA, CE, FCC, UL, and TUV, along with over voltage, over power, short circuit, and thermal overload protection. This comprehensive approach to safety makes it a robust choice for demanding systems. Conversely, the iUniker GaN PD 27W power supply also includes over voltage, over current, and short circuit protection, ensuring safety for its intended use with devices like the Raspberry Pi 5. While both products provide essential safety measures, the level of protection and certification is more extensive in the JUSTOP model.

Cooling Solutions

Cooling is crucial for maintaining the performance and longevity of power supplies. The JUSTOP Black 750W PSU features a 120mm cooling fan, which helps to manage temperature during high-load situations. This is particularly important in a desktop environment where heat can accumulate due to multiple components. In contrast, the iUniker GaN PD 27W power supply does not specify a cooling mechanism, likely relying on its efficient design and lower heat generation due to GaN technology. The presence of an active cooling solution in the JUSTOP model may make it more suitable for high-performance setups, while the iUniker is adequate for lower-power applications where heat is less of a concern.

Which should you buy?

Choosing between the JUSTOP Black 750W PSU and the iUniker GaN PD 27W power supply ultimately depends on your specific needs. If you require a high-capacity power supply for a powerful desktop PC, the JUSTOP model with its 750W output and comprehensive safety features is the clear choice, albeit at a higher price of £32.95. However, if you are looking for a cost-effective solution for a Raspberry Pi 5 or similar low-power device, the iUniker at £13.79 offers excellent value with its modern GaN technology and sufficient output for less demanding applications. Therefore, your decision should be based on the power requirements of your devices and your budget.
