ASRock PRO 750G vs iRasptek 27W USB-C Power Supply with PD for Raspberry Pi 5（5.1V/5A）

Price Comparison

The ASRock PRO 750G is priced at C$89.94, while the iRasptek 27W USB-C Power Supply costs significantly less at C$21.99. This substantial price difference may initially suggest that the iRasptek product offers better value; however, this comparison must account for the specific applications and power needs of each product. The ASRock PRO 750G is a high-capacity power supply designed for medium to high-performance computer systems, making it suitable for demanding tasks. In contrast, the iRasptek power supply is tailored for the Raspberry Pi 5, providing a lower power output but optimised for its requirements.

Power Capacity

The ASRock PRO 750G delivers a robust 750W of power, making it ideal for high-performance systems that require reliable and stable power distribution. This capacity supports configurations with modern graphics cards and ensures longevity during intensive operations. On the other hand, the iRasptek 27W USB-C Power Supply offers a maximum output of 27W, which is sufficient for lower-powered devices like the Raspberry Pi 5. This stark difference in power capacity illustrates the distinct user bases each product caters to, with the ASRock PRO 750G aimed at gamers and workstation users, while the iRasptek product targets hobbyists and developers using the Raspberry Pi.

Efficiency Ratings

The ASRock PRO 750G boasts an impressive 80 Plus Gold certification, achieving up to 90% energy efficiency. This not only reduces energy waste but also lowers operating costs over time. In contrast, the iRasptek power supply does not specify an energy efficiency rating, which could indicate less focus on efficiency compared to the ASRock unit. For users concerned about energy consumption and long-term costs, the ASRock PRO 750G presents a more appealing option due to its certified efficiency, benefiting both the environment and the user's wallet.

Compatibility

The ASRock PRO 750G is compatible with ATX 3.1 and PCIe 5.1 standards, ensuring it can support the latest components in modern PCs. It features a native 12V-2x6 jack designed to provide up to 450W specifically for high-performance graphics cards. This level of compatibility makes it an ideal choice for gamers and tech enthusiasts looking to build or upgrade their systems. Conversely, the iRasptek 27W USB-C Power Supply is specifically designed for the Raspberry Pi 5 and supports various power delivery profiles, including 5.1V/5A, 9V/3A, 12V/2.25A, and 15V/1.8A. This versatility allows it to power various peripherals connected to the Raspberry Pi, making it suitable for users wanting to expand their device's capabilities.

Cooling Solutions

The cooling features of the ASRock PRO 750G include a 120mm silent cooling fan, optimised for low-noise operation while maintaining effective heat management. This is particularly beneficial for users who value a quiet computing environment, whether for gaming or workstation use. In contrast, the iRasptek 27W USB-C Power Supply does not explicitly mention any cooling solutions, which may make it less appealing for extended use with high-power peripherals. The emphasis on efficient cooling in the ASRock PRO 750G underscores its design for performance stability, especially during demanding tasks.

Warranty and Support

The ASRock PRO 750G comes with a 3-year warranty, providing peace of mind for users concerned about the reliability of their power supply. This warranty reflects the manufacturer's confidence in the product's durability and performance over time. The iRasptek 27W USB-C Power Supply does not specify a warranty period within the provided information, which may leave potential buyers uncertain about its long-term reliability. For users prioritising warranty and support, the ASRock PRO 750G offers a more reassuring choice.

Use Cases

The ASRock PRO 750G is designed for users with medium to high-performance systems, making it perfect for gaming, video editing, and other demanding applications. Its high wattage and efficiency make it suitable for setups requiring substantial power and stability. In contrast, the iRasptek 27W USB-C Power Supply is intended for users of the Raspberry Pi 5, particularly those who want to connect high-power peripherals such as hard drives and SSDs. This product is specifically crafted for a niche market, making it a more specialised option compared to the broadly applicable ASRock PRO 750G.

Which should you buy?

When choosing between the ASRock PRO 750G and the iRasptek 27W USB-C Power Supply, the decision largely depends on your specific needs. If you require a reliable, high-capacity power supply for a gaming rig or a workstation, the ASRock PRO 750G is undoubtedly the superior choice with its 750W output, 80 Plus Gold certification, and compatibility with modern standards. However, if your focus is on powering a Raspberry Pi 5 or similar lower-powered devices, the iRasptek 27W power supply offers excellent value at a significantly lower price, designed specifically for that purpose. Therefore, assess your requirements carefully to determine the best fit for your setup.
