iUniker GaN PD 27W 5.1V 5A 27W PD Power Supply USB-C for Raspberry Pi 5 vs JUSTOP Black ATX 500W PSU

Price Comparison

When it comes to pricing, the iUniker GaN PD 27W power supply is significantly more affordable at £13.79 compared to the JUSTOP Black ATX 500W PSU, which is priced at £22.50. This £8.71 difference highlights the iUniker as a budget-friendly option, especially for users who need a power supply specifically for their Raspberry Pi 5. However, the price reflects the power capacity; the iUniker provides a maximum output of 27 watts, while the JUSTOP supplies a much more substantial 500 watts. Therefore, the choice may depend on the intended application and required power output.

Compatibility

The iUniker GaN PD 27W power supply is explicitly designed for compatibility with Raspberry Pi 5 variants, such as the 4GB and 8GB models. This targeted compatibility ensures that users can easily integrate it with their Raspberry Pi devices without concerns about connectivity issues. On the other hand, the JUSTOP Black ATX 500W PSU is suited for desktop PCs and is compatible with a variety of brands and models. This makes it ideal for users building or upgrading their PCs. The choice between these two products hinges on whether the user seeks a power supply for a Raspberry Pi or for a general desktop setup.

Power Capacity

Power capacity is a crucial factor when selecting a power supply, and this is where the two products diverge significantly. The iUniker power supply offers a maximum output of 27 watts, sufficient for the Raspberry Pi's requirements. In contrast, the JUSTOP PSU delivers a robust 500 watts, allowing it to support more demanding desktop systems, including those with higher power needs like gaming rigs. This vast difference in power output makes the JUSTOP the go-to choice for users needing to power multiple components or peripherals, while the iUniker is perfectly adequate for low-power devices.

Technology and Efficiency

The iUniker GaN PD power supply utilises GaN technology, which allows for a compact design without compromising efficiency. This technology also results in a cooler operating temperature, providing stability and longevity. In contrast, the JUSTOP PSU features a 120mm cooling fan designed to maintain optimal operating temperatures during use. While both products have mechanisms to manage heat, the advanced GaN technology of the iUniker may offer advantages in smaller setups where space and heat generation are critical.

Safety Features

Safety is paramount in power supply design. The iUniker power supply includes several protective features, such as over voltage, over current, and short circuit protection, ensuring the connected devices are safeguarded against electrical faults. Similarly, the JUSTOP PSU incorporates multiple safety certifications, including UKCA, CE, FCC, UL, and TUV, alongside its own protective features like over voltage protection, over power protection, and thermal overload cut-off. Both products provide robust safety measures, but the JUSTOP’s extensive safety certifications may offer additional peace of mind to users concerned about electrical safety.

Size and Form Factor

The iUniker power supply is compact, making it an excellent choice for users with limited space, such as those working with Raspberry Pi setups. It is designed for direct use with USB-C connections, which are often found in smaller electronics. Conversely, the JUSTOP PSU is an ATX form factor power supply, designed for traditional desktop setups. Its larger size accommodates more powerful components and a more extensive array of connectors. Users needing a compact solution may prefer the iUniker, while those building a full desktop system would benefit from the size and capabilities of the JUSTOP.

Installation and Connectivity

The installation process for each product reflects their intended use. The iUniker GaN PD power supply utilises a simple USB-C connection, making it straightforward to connect to a Raspberry Pi without additional adapters. Conversely, the JUSTOP PSU comes with a variety of connectors, including a 20+4 pin connector, 4+4 pin, and multiple SATA and Molex connectors, allowing it to interface with numerous types of desktop components. This array of connections is beneficial for users assembling a desktop PC, while the iUniker's simplicity is advantageous for those focused on single-board computing.

Which should you buy?

The decision ultimately hinges on your specific needs. If you require a power supply for a Raspberry Pi, the iUniker GaN PD 27W is the clear choice due to its affordability, compact design, and compatibility. However, if you are building or upgrading a desktop PC that demands higher power output, the JUSTOP Black ATX 500W PSU is the superior option, offering significantly greater wattage, extensive connectivity options, and robust safety features. Thus, choose based on whether you need a compact solution for low-power applications or a powerful, versatile supply for a desktop environment.
