Dimension comparison
Overview
When comparing power supplies, the CORSAIR RM750x Shift and the Raspberry Pi 15W USB-C Power Supply stand out for different reasons. The CORSAIR RM750x Shift is designed for high-performance systems while the Raspberry Pi power supply caters specifically to the needs of Raspberry Pi devices. Understanding their intended use and features is crucial when deciding which one suits your needs better.
Price Comparison
The CORSAIR RM750x Shift retails for $79.99, while the Raspberry Pi 15W USB-C Power Supply is priced at just $16.37. This makes the Raspberry Pi power supply about 80% cheaper than the CORSAIR model. However, the price difference reflects their intended purposes—one is built for demanding PC builds, and the other is geared towards simple, low-power applications like the Raspberry Pi.
Performance and Efficiency
The CORSAIR RM750x Shift boasts an 80 PLUS Gold certification, indicating superior energy efficiency. This means it converts a higher percentage of electricity from the wall into usable power for your components, leading to lower electricity bills in the long run. In contrast, the Raspberry Pi power supply delivers a modest 15 watts of power, adequate for its intended use but not comparable to the performance capabilities of the CORSAIR model.
Build Quality and Durability
The CORSAIR RM750x Shift is built with 100% 105°C-rated Japanese electrolytic capacitors, ensuring long-term reliability and performance. It also features a ten-year warranty, which speaks to its durability. The Raspberry Pi power supply, while functional, does not emphasize high-end materials or long-term durability in its design, reflecting its more basic purpose and lower price point.
Connectivity and Features
The CORSAIR RM750x Shift features a side cable interface, allowing for easier access and cleaner cable management. This fully modular design means you only connect the necessary cables, which is a significant advantage for complex PC builds. On the other hand, the Raspberry Pi power supply uses a USB-C connector specifically designed for the Raspberry Pi 4 Model B. Its simplicity is an advantage for those who prioritize ease of use over extensive features.
Noise Levels
The CORSAIR RM750x Shift incorporates a 140mm fluid dynamic bearing fan, designed for high performance while producing minimal noise. It also offers a Zero RPM mode, ensuring quiet operation at low to medium loads. In contrast, the Raspberry Pi power supply operates silently due to its lack of moving parts, but it falls short in terms of performance under heavy loads or complex setups.
Target Audience
The CORSAIR RM750x Shift is aimed at gamers and PC enthusiasts who need a reliable and efficient power source for high-performance components. Its features cater to those who prioritize performance and aesthetics in their builds. The Raspberry Pi power supply, however, is targeted toward hobbyists and developers using Raspberry Pi devices for projects that do not require significant power, making it ideal for low-energy applications.
Compatibility
The CORSAIR RM750x Shift is compatible with a wide range of components, including the latest PCIe Gen 5.1 platforms, making it a versatile choice for future-proofing your PC. In contrast, the Raspberry Pi power supply is specifically designed for the Raspberry Pi 4 Model B, limiting its use to that particular device. This specificity may be advantageous for Raspberry Pi users but shows a clear difference in versatility compared to the CORSAIR model.
Which should you buy?
Ultimately, the choice between the CORSAIR RM750x Shift and the Raspberry Pi 15W USB-C Power Supply depends on your specific needs. If you are building a high-performance PC and require a robust power supply, the CORSAIR model is the clear winner with its advanced features, efficiency, and build quality. However, if you are simply looking for a reliable power source for a Raspberry Pi device, the Raspberry Pi power supply offers excellent value at a fraction of the price.
