iUniker GaN PD 27W 5.1V 5A 27W PD Power Supply USB-C for Raspberry Pi 5 vs be quiet! System Power 11 750W Power Supply

Price Comparison

The iUniker GaN PD 27W power supply is significantly more affordable than the be quiet! System Power 11, priced at £13.79 compared to £64.99. This vast difference in price reflects the intended use and target market of each product. The iUniker power supply is designed specifically for Raspberry Pi 5 systems, making it an economical choice for hobbyists and developers. In contrast, the be quiet! power supply is aimed at high-performance gaming and workstation setups, justifying its higher price tag. For those on a budget or looking for a specific solution for their Raspberry Pi, the iUniker is clearly the more cost-effective option.

Compatibility

The iUniker GaN PD power supply is tailored for compatibility with the Raspberry Pi 5, ensuring a perfect match for users of this platform. It supports both the 4GB and 8GB versions of the Raspberry Pi 5, making it versatile for various applications within that ecosystem. On the other hand, the be quiet! System Power 11 750W caters to a broader market with its ATX 3.1 PSU design, supporting next-generation PCIe 5.1 graphics cards and current-generation GPUs with its multiple PCIe connectors. This makes the be quiet! power supply suitable for a wide range of PC builds, from gaming to professional use, while the iUniker serves a more niche audience.

Technology

The iUniker power supply utilises GaN technology, which allows for a more compact design without compromising on power output. This technology enables the adapter to operate at lower temperatures and provides stable performance. In contrast, the be quiet! System Power 11 features traditional PSU technology but excels with its ability to handle power excursions up to double its rated output. This capability ensures reliability under heavy loads, making it ideal for high-performance systems. While the iUniker is designed for efficiency and portability, the be quiet! focuses on robustness and versatility.

Performance

The performance specifications of the iUniker GaN PD power supply indicate an output range of 5.1V/5A, 9V/3A, 12V/2.25A, and 15V/1.8A, ensuring it meets the power requirements of the Raspberry Pi 5 effectively. Conversely, the be quiet! System Power 11 is rated at a robust 750W, providing stable and dependable power for both CPUs and GPUs, particularly under heavy loads. Its 80 PLUS Bronze certification translates to an efficiency rating of up to 90.0%, which is advantageous for energy-conscious users. Thus, while the iUniker is sufficient for low-power applications, the be quiet! is built for demanding performance environments.

Noise Levels

The iUniker power supply operates silently due to its compact design and lack of moving parts. This is particularly beneficial for Raspberry Pi users who may be using their devices in quiet environments. In contrast, the be quiet! System Power 11 is equipped with a temperature-controlled 120mm quality fan designed to minimise noise. This fan delivers a low-noise operation, which is a hallmark of the be quiet! brand. While both products aim for quiet operation, the iUniker has the advantage of being fanless, making it truly silent, while the be quiet! balances performance with noise management.

Safety Features

Both power supplies prioritise safety, but they do so in different ways. The iUniker GaN PD power supply includes overvoltage, overcurrent, and short circuit protection, which are critical for safeguarding the Raspberry Pi against power anomalies. In contrast, the be quiet! System Power 11 offers a broader range of safety protections, including safeguards against overcurrents, over- and undervoltages, overheating, short circuits, and overloads. This extensive set of features is crucial for users who demand reliability in high-performance environments. While both products are designed with safety in mind, the be quiet! power supply provides a more comprehensive suite of protections.

Build Quality

The build quality of the iUniker power supply is reflected in its compact and efficient design, utilising GaN technology to create a smaller footprint. However, its specific focus on low-power applications may limit its robustness compared to traditional larger PSUs. The be quiet! System Power 11, on the other hand, is built to handle demanding tasks, showcasing a sturdy design that accommodates high wattage and performance. Its 120mm fan also contributes to maintaining optimal operating temperatures, highlighting a commitment to longevity and reliability. For users prioritising durability and performance, the be quiet! is likely the superior choice.

Which should you buy?

Deciding between the iUniker GaN PD 27W power supply and the be quiet! System Power 11 ultimately comes down to your specific needs. If you are looking for an affordable, efficient solution for your Raspberry Pi 5, the iUniker power supply is an excellent choice at £13.79. However, if you require a high-performance, versatile power supply capable of supporting demanding PC builds, the be quiet! System Power 11 at £64.99 is the better investment. Each product excels in its intended use, making it essential to consider your requirements before making a purchase.
