iUniker GaN PD 27W 5.1V 5A 27W PD Power Supply USB-C for Raspberry Pi 5 vs JUSTOP Black 700W Power Supply Unit ATX PSU With 120MM Quiet Fan

Overview of iUniker GaN PD 27W Power Supply and JUSTOP Black 700W Power Supply Unit

The iUniker GaN PD 27W Power Supply is designed specifically for Raspberry Pi, while the JUSTOP Black 700W Power Supply Unit caters to desktop PCs. Both serve distinct purposes, with the iUniker priced at £13.79 and the JUSTOP at £29.95, showcasing their target markets. The iUniker offers compactness and efficiency for Raspberry Pi users, while the JUSTOP provides robust power for gaming or high-performance systems.

Design and Build Quality

The iUniker GaN PD Power Supply is compact and lightweight, thanks to GaN technology, which allows it to maintain high power output in a smaller form factor. This makes it a convenient option for Raspberry Pi setups that require minimal space. On the other hand, the JUSTOP Black 700W Power Supply features a more traditional ATX design with a 120mm quiet fan for cooling, ensuring effective heat management during intensive usage. The build quality of both products is commendable, but their designs reflect their different applications.

Compatibility and Use Cases

The iUniker GaN PD Power Supply is compatible with Raspberry Pi 5 models, specifically the 4GB and 8GB variants. It operates within an input voltage range of 100–240V AC and outputs power efficiently at various voltage levels. Conversely, the JUSTOP Black 700W Power Supply is compatible with Intel ATX 12V v.2.3 and EPS 12V v.2.92 standards, making it suitable for a wide range of desktop PCs. Each product serves specific needs — the iUniker for compact, low-power applications, and the JUSTOP for high-demand systems.

Performance and Efficiency

The iUniker offers an impressive output of 5.1V at 5A, achieving a maximum power of 27W. The use of GaN technology ensures it operates efficiently without overheating, making it ideal for continuous use with Raspberry Pi. In contrast, the JUSTOP Black 700W Power Supply delivers up to 700W of power, supporting high-performance components with a 70% efficiency rating. This performance capability allows it to handle demanding tasks such as gaming or video editing without compromising stability.

Safety Features

Safety is paramount in both products, with the iUniker featuring over voltage, over current, and short circuit protection. These features provide peace of mind for users of the Raspberry Pi, especially in DIY projects. The JUSTOP Black 700W Power Supply also boasts extensive safety features, including over voltage protection, over power protection, and thermal overload cut-off protection. Both products are designed with user safety in mind, ensuring reliable operation during varied usage scenarios.

Cooling Mechanisms

The cooling mechanisms in both power supplies differ significantly, reflecting their intended use. The iUniker's compact design doesn't include an active cooling system, relying instead on efficient heat dissipation through its small form factor. In contrast, the JUSTOP Black 700W Power Supply is equipped with a 120mm quiet fan that enhances airflow and helps maintain optimal operating temperatures, particularly under heavy loads. This active cooling makes the JUSTOP more suitable for extended high-performance tasks.

Price and Value

The iUniker GaN PD Power Supply is priced at £13.79, providing excellent value for Raspberry Pi users who need a reliable and efficient power source. Its affordability and specialised design make it a wise investment for hobbyists and developers. On the other hand, the JUSTOP Black 700W Power Supply, at £29.95, offers substantial power capacity and versatility for desktop PCs. While it is more expensive, its robust features and high power output justify the price for users seeking a reliable PSU for demanding applications.

Which should you buy?

Ultimately, the choice between the iUniker GaN PD 27W Power Supply and the JUSTOP Black 700W Power Supply Unit depends on your specific needs. If you require a compact, efficient power supply for a Raspberry Pi setup, the iUniker is the ideal choice at £13.79. However, if you are building or upgrading a desktop PC that demands substantial power and stability, the JUSTOP at £29.95 provides the necessary features and capacity for high-performance tasks. Each power supply excels in its domain, making the decision straightforward based on your intended use.
