CORSAIR CX650 80 PLUS Bronze Non Modular Low-Noise ATX 650 Watt Power Supply - U vs GeeekPi USB-C Power Supply UK Plug for Raspberry Pi 4 With On/Off Switch

Overview of the Products

When comparing the CORSAIR CX650 80 PLUS Bronze Non Modular Low-Noise ATX 650 Watt Power Supply and the GeeekPi USB-C Power Supply for Raspberry Pi, it’s clear that these two products cater to very different needs. The CORSAIR power supply is a high-capacity unit designed for full PC builds, while the GeeekPi power supply is specifically tailored for Raspberry Pi devices. Priced at £44.99, the CORSAIR unit offers robust features suitable for gaming and high-performance tasks, whereas the GeeekPi comes in at a budget-friendly £11.99, making it an economical choice for Raspberry Pi enthusiasts.

Power Output Capabilities

The CORSAIR CX650 boasts an impressive continuous power rating of 650 watts, making it ideal for demanding systems that require stable and high output. This ensures that users can run multiple components without fear of power shortages. On the other hand, the GeeekPi power supply outputs 5V at 3.6A, which translates to 18 watts. This is perfectly sufficient for powering Raspberry Pi models, but it cannot support the more power-intensive setups that the CORSAIR can handle.

Efficiency Ratings

Efficiency is a critical factor in power supplies, and the CORSAIR CX650 shines with its 80 PLUS Bronze certification, which guarantees up to 88% operational efficiency. This not only reduces heat generation but also lowers energy costs, an essential consideration for users running high-performance PCs continuously. In contrast, the efficiency of the GeeekPi power supply is not explicitly stated, but it is designed for stable usage with a focus on compatibility rather than energy efficiency metrics.

Cooling Mechanisms

Cooling is essential for maintaining performance and longevity in power supplies. The CORSAIR CX650 features a 120mm thermally controlled fan that operates quietly by adjusting its speed based on the load, ensuring minimal noise during lighter tasks. This design is particularly beneficial for users who prefer a quieter computing experience. The GeeekPi power supply, however, does not mention any specific cooling features, which is typical for lower-powered devices that generate less heat compared to high-capacity units.

Design and Build Quality

The design of the CORSAIR CX650 includes a compact casing measuring 125mm in length, making it suitable for most modern PC cases. Its black sleeved cables and powder-coated casing ensure that it fits seamlessly with various aesthetic preferences in PC builds. Meanwhile, the GeeekPi power supply’s design is straightforward, featuring a practical UK plug and a 120cm extended cord for flexibility. While it is functional, it lacks the sleek aesthetics and build quality that the CORSAIR offers.

User Convenience Features

The CORSAIR CX650 is designed with ease of installation in mind, ensuring that it can fit into a variety of PC cases without hassle. Additionally, its low-noise operation enhances user experience. Conversely, the GeeekPi power supply includes an ON/OFF switch, allowing users to easily power their Raspberry Pi on and off without needing to plug and unplug the device. This feature adds a layer of convenience, particularly for users who frequently need to turn their devices on and off.

Safety and Protection Measures

Safety features are crucial in power supplies to prevent damage to connected devices. The CORSAIR CX650 guarantees full continuous power and includes various built-in protections, although specific details are not provided in the features. The GeeekPi, however, is explicitly noted for its multiple protection functions, including over-current, short-circuit, over-voltage, low-voltage, over-temperature, and electrostatic protections. This extensive safety system is particularly appealing for users concerned about the risks associated with powering sensitive electronics like the Raspberry Pi.

Which should you buy?

Choosing between the CORSAIR CX650 and the GeeekPi USB-C Power Supply ultimately depends on your specific needs. If you require a robust power supply capable of supporting high-performance PCs, the CORSAIR unit is the clear winner with its 650 watts of power, efficiency, and low-noise operation. However, for Raspberry Pi users looking for an affordable, compact solution, the GeeekPi power supply stands out with its ease of use and built-in safety features. Therefore, your choice should be guided by whether you need high power for gaming and demanding applications or a simple, efficient power source for your Raspberry Pi project.
