GeeekPi 20W 5V 4A Power Supply for Raspberry Pi 4/Orange Pi 5/5B vs Redragon RGPS-850W 80+ Gold 850 Watt Power Supply w/Upgraded ATX 3.1 & PCIe 5.1

Price Comparison

When considering price, the GeeekPi 20W 5V 4A Power Supply is significantly more affordable at C$31.40 compared to the Redragon RGPS-850W, which retails for C$154.99. This difference of C$123.59 is substantial, especially for budget-conscious consumers. The GeeekPi power supply is designed for lower-demand devices like the Raspberry Pi 4 and Orange Pi, while the Redragon caters to high-performance gaming setups, justifying its higher price point with its superior specifications and capabilities.

Compatibility

Compatibility is a crucial factor when choosing a power supply. The GeeekPi power supply is specifically tailored for Raspberry Pi 4 and Orange Pi models, ensuring that users will have a seamless experience with these devices. It also includes a Type-C to Micro USB adapter for older Raspberry Pi models, demonstrating its versatility. On the other hand, the Redragon RGPS-850W is designed for high-performance computers, supporting the latest ATX 3.1 and PCIe 5.1 standards. This makes it suitable for modern gaming rigs that require significant power. Therefore, if you are using a Raspberry Pi, the GeeekPi is ideal, while the Redragon is better for high-performance PCs.

Certification and Efficiency

In terms of efficiency and certification, the Redragon RGPS-850W excels with its 80 Plus Gold certification, which ensures higher energy efficiency and lower noise levels. This certification indicates that the power supply operates at a high efficiency, reducing heat output and improving overall system performance. Conversely, the GeeekPi power supply, while it does not mention a specific efficiency rating, is UL Listed and holds TUV and RoHS certifications, which indicates safety and compliance with international standards. However, the efficiency factor leans heavily in favour of the Redragon, especially for users looking to optimise their energy consumption.

Build Quality

Build quality is another area where the Redragon RGPS-850W stands out. It is constructed with 100% Japanese capacitors, known for their reliability and durability, which is important for maintaining stable power delivery, especially during high-demand situations. The zero RPM mode for the fan adds to its appeal by ensuring silent operation until the system temperature reaches 60℃. In contrast, the GeeekPi power supply focuses on stability with high-quality copper wire and an inline noise filter, but it lacks the advanced cooling and build features of the Redragon. Therefore, if build quality and long-term reliability are your primary concerns, the Redragon is a more robust option.

Cooling and Noise Levels

Cooling performance and noise levels are critical for maintaining an efficient and quiet workspace. The Redragon RGPS-850W features a zero RPM mode fan that operates only when the temperature exceeds 60℃, ensuring a quieter environment when the system is under light load. This design is particularly beneficial for gamers and professionals who require a noise-free setup. In contrast, while the GeeekPi power supply does not mention any specific cooling features, it is designed for lower power consumption and less heat generation, making it inherently quieter. However, for users who need high performance and can incur some noise for enhanced cooling, the Redragon offers a more advanced solution.

Power Output

The power output capabilities of the two products differ greatly. The GeeekPi power supply delivers a modest 20W at 5V, which is sufficient for the low power requirements of devices like the Raspberry Pi 4. On the other hand, the Redragon RGPS-850W provides a whopping 850W, making it suitable for high-performance gaming PCs and workstations. This immense power output allows it to support demanding components like the latest Nvidia and AMD graphics cards. Hence, if you require a power supply for basic computing tasks, the GeeekPi is adequate, but for gaming and heavy workloads, the Redragon is essential.

Aesthetics and Design

When it comes to aesthetics and design, the Redragon RGPS-850W shines with its sleek, compact size of 160mm, which enhances compatibility with various chassis and promotes tidy cable management. Additionally, it boasts up to 9 RGB modes, allowing users to customise the lighting to match their setup, adding a personal touch to the gaming rig. In contrast, the GeeekPi power supply has a straightforward design aimed at functionality rather than visual appeal. While it serves its purpose well, it does not offer the same level of aesthetic customisation as the Redragon. Thus, for users who value visual style alongside performance, the Redragon RGPS-850W is the clear winner.

Which should you buy?

In conclusion, the choice between the GeeekPi 20W 5V 4A Power Supply and the Redragon RGPS-850W 80+ Gold 850 Watt Power Supply ultimately depends on your specific needs. If you're looking for an affordable, compact solution for low-power devices like the Raspberry Pi 4 or Orange Pi, the GeeekPi is an excellent choice at C$31.40. However, if your requirements include powering a high-performance gaming PC with the latest components, the Redragon RGPS-850W, despite its higher price of C$154.99, offers superior power output, efficiency, and features that justify the investment. Consider your power needs and budget carefully to make the best decision.
