GeeekPi 20W 5V 4A Power Supply for Raspberry Pi 4/Orange Pi 5/5B vs SAMA Black 850W Power Supply - Fully Modular 80 Plus Gold Certified ATX 3.1 & PC

Price Comparison

The GeeekPi 20W 5V 4A Power Supply is priced at C$31.40, while the SAMA Black 850W Power Supply comes in significantly higher at C$89.99. This price difference reflects not only the different power outputs but also the intended uses of each product. The GeeekPi power supply is designed specifically for Raspberry Pi and Orange Pi devices, providing sufficient power for hobbyist projects. In contrast, the SAMA power supply is aimed at high-performance PCs, particularly those using demanding components like high-end GPUs. Thus, the pricing strategy aligns with the target market and capabilities of each product.

Power Output

The power output of each supply is drastically different, with the SAMA Black offering 850W compared to the GeeekPi's 20W. This substantial difference indicates that the SAMA power supply is suited for powering complete computer systems, including multiple high-performance components, while the GeeekPi is tailored for low-power devices like the Raspberry Pi 4 and Orange Pi. The SAMA's extensive power capacity means it can handle demanding tasks, making it ideal for gaming and workstation setups, while the GeeekPi provides just enough for basic operations and projects.

Design and Modularity

The SAMA Black features a fully modular design, allowing users to connect only the cables they need. This design is particularly advantageous for maintaining a clean and efficient setup, improving airflow and cooling performance. In contrast, the GeeekPi power supply does not mention modularity, indicating it comes with fixed cables. The streamlined cable management of the SAMA can facilitate easier builds and upgrades, while the GeeekPi may not offer the same level of convenience, particularly for users looking to optimise their space or airflow.

Certification and Efficiency

The SAMA power supply boasts dual certifications: 80 PLUS Gold and CYBENETICS Gold, achieving up to 91.15% efficiency at 50% load. This level of efficiency reduces energy waste and enhances overall system stability. The GeeekPi power supply, while certified with UL, TUV, and RoHS, does not provide specific efficiency metrics. The high efficiency of the SAMA could lead to lower electricity costs over time, making it a more energy-conscious choice for long-term use, especially when powering a full PC setup.

Cooling Mechanism

Cooling is a critical aspect of power supplies, especially under heavy loads. The SAMA Black is equipped with a 120mm ECO fan featuring Fluid Dynamic Bearing (FDB) technology, which operates quietly at noise levels as low as ≤20dB-A. This ensures that even during intense gaming or heavy processing tasks, the power supply operates discreetly. The GeeekPi does not specify any cooling features, suggesting it may rely on passive cooling methods. Therefore, users who prioritise quiet operation during high-performance tasks might prefer the SAMA for its advanced cooling technology.

Build Quality and Reliability

The SAMA power supply is constructed with premium Japanese capacitors, which are known for their reliability and stability in power delivery. It also comes with a five-year warranty, underscoring the manufacturer's confidence in its durability. In contrast, specific details on the build quality of the GeeekPi power supply are not provided, which may leave users questioning its longevity, especially when considering it for long-term projects. The superior components and warranty of the SAMA could give it an edge in terms of overall reliability.

Intended Use Cases

The GeeekPi power supply is specifically designed for Raspberry Pi and Orange Pi devices, making it ideal for hobbyists, educators, and light computing tasks. Its features cater to users who need a straightforward and reliable power solution for their low-power projects. Conversely, the SAMA Black is geared towards gamers and professionals needing a robust power supply for high-performance PCs. This clear distinction in intended use cases illustrates that while both products serve as power supplies, their applications are vastly different.

Which should you buy?

If you're looking for a cost-effective and straightforward power supply for Raspberry Pi or Orange Pi projects, the GeeekPi 20W 5V 4A Power Supply is a solid choice at C$31.40. However, if you require a high-capacity power supply for a gaming rig or a workstation that demands reliability and performance, the SAMA Black 850W Power Supply at C$89.99 is the better option. Ultimately, your decision should hinge on your specific needs—whether for casual projects or high-performance computing.
