SAMA B850 850W ATX Power Supply vs GeeekPi 18W 5V 3.6A Power Supply for Raspberry Pi 4

Price Comparison

When it comes to price, the SAMA B850 850W ATX Power Supply is significantly more expensive than the GeeekPi 18W 5V 3.6A Power Supply. The SAMA B850 retails for C$74.99, while the GeeekPi is priced at a much lower C$16.99. This difference of C$58.00 reflects the distinct target markets of these two products; the SAMA B850 is designed for high-performance PCs and gaming setups, whereas the GeeekPi is tailored specifically for Raspberry Pi users. Therefore, your budget will play a crucial role in determining which power supply is the better choice for you.

Power Output

The SAMA B850 boasts a substantial output of 850 watts, making it suitable for high-end gaming rigs and modern motherboards that require significant power, including support for the latest RTX 4090/50 series GPUs. In contrast, the GeeekPi delivers 18 watts at 5V and 3.6A, which is specifically engineered to meet the needs of Raspberry Pi 4 users. The dramatic difference in power output—850W versus 18W—highlights the SAMA B850's capability for demanding applications compared to the limited requirements of the GeeekPi, which is more than adequate for powering a Raspberry Pi.

Efficiency Ratings

The SAMA B850 is 80 PLUS Bronze Certified, which means it operates with over 85% efficiency at typical loads. This certification not only signifies energy efficiency but also translates to potential savings on electricity bills over time. In contrast, the GeeekPi does not provide a specific efficiency rating but is geared towards providing stable power for the Raspberry Pi at a lower output. While the SAMA B850 offers energy-efficient performance for high-end builds, the GeeekPi focuses on delivering adequate power without the need for high efficiency, given its low power requirements.

Compatibility

Compatibility is a critical factor when choosing a power supply, and both options cater to different needs. The SAMA B850 is ATX 3.1 and PCIe 5.1 ready, making it compatible with the latest motherboards and high-performance GPUs. This level of compatibility ensures that it can support future upgrades in a gaming or workstation build. Meanwhile, the GeeekPi is specifically designed for use with Raspberry Pi 4, Pi 3B+, and 3B models, providing a Type-C to Micro USB adapter for broader compatibility. This targeted approach means that while the SAMA B850 can support a range of devices, the GeeekPi excels in its niche market.

Design and Aesthetics

In terms of design, the SAMA B850 features sleek black flat cables, which not only enhance cable management but also improve airflow within a PC case. This design consideration is essential for gamers and PC builders who prioritize aesthetics and functionality. The quiet fan cooling system further adds to its appeal, ensuring a quieter operation while maintaining optimal performance. On the other hand, the GeeekPi has a more utilitarian design, featuring an ON/OFF switch for convenience, which is practical for Raspberry Pi users. While the SAMA B850 focuses on aesthetics suitable for high-end builds, the GeeekPi is designed for straightforward usability.

Cooling Features

Effective cooling is vital for maintaining the longevity and performance of power supplies. The SAMA B850 is equipped with a temperature-controlled fan that ensures quiet operation while efficiently cooling the power supply during use. This feature is especially important for high-performance systems that generate more heat. Conversely, the GeeekPi does not specifically mention any cooling features, which is acceptable given its lower power output. The lack of detailed cooling specifications suggests that the GeeekPi may not require advanced cooling solutions, focusing instead on stable power delivery for the Raspberry Pi.

Warranty and Protection

Warranty and protection features are essential considerations when purchasing a power supply. The SAMA B850 comes with a 3-year warranty and includes full protections such as Over Voltage Protection (OVP), Over Current Protection (OCP), Over Temperature Protection (OTP), and Short Circuit Protection (SCP). This extensive coverage provides peace of mind for users investing in high-performance setups. In comparison, the GeeekPi also boasts multiple protection functions, including over voltage, under voltage, over temperature, over current, and short circuit protections. While both power supplies offer solid protection, the SAMA B850’s longer warranty period may be more appealing for consumers looking for long-term reliability.

Which should you buy?

Choosing between the SAMA B850 850W ATX Power Supply and the GeeekPi 18W 5V 3.6A Power Supply ultimately depends on your specific needs. If you are building a high-performance gaming rig or workstation that requires significant power and efficiency, the SAMA B850 is the clear winner with its robust output, efficiency certification, and extensive compatibility. However, if you are simply looking to power a Raspberry Pi, the GeeekPi offers an affordable, efficient, and reliable solution tailored specifically for that purpose. Your decision should hinge on your power requirements, budget, and intended use case.
