CanaKit 45W USB-C Power Supply with PD for Raspberry Pi 5 vs Rosewill VMG 850W 80+ Gold, ATX 3.0 & 3.1

Overview of the Products

The CanaKit 45W USB-C Power Supply and the Rosewill VMG 850W 80+ Gold serve different purposes in the realm of power supplies. The CanaKit is priced at $15.77, whereas the Rosewill costs $74.97, making it approximately 376% more expensive. While the CanaKit is specifically designed for the Raspberry Pi 5, the Rosewill caters to high-performance PCs needing substantial power.

Design and Build Quality

The CanaKit features a compact design with a thick and insulated 4-foot cable, enhancing its stability and usability. In contrast, the Rosewill boasts a full modular design, facilitating a cleaner build and more efficient cable management. Its chassis dimensions are compact, measuring 140×150×86 mm, making it about 35% smaller than typical power supplies, which is advantageous for small-form-factor builds. Both power supplies are constructed with quality in mind, ensuring durability and reliability.

Power Output and Compatibility

CanaKit's power supply delivers a maximum of 45W, with a specific output of 27W at 5A, perfectly tailored for the Raspberry Pi 5 and compatible with other USB-C devices. On the other hand, the Rosewill VMG offers an impressive 850W, making it suitable for high-end graphics cards and gaming PCs. The Rosewill is equipped with a PCIe 5.1 12+4 Pin connector that can deliver 600W directly to the latest GPUs, which is a substantial advantage for gamers or professionals requiring high power.

Efficiency and Certification

The Rosewill VMG 850W is 80 PLUS Gold certified, indicating high energy efficiency and lower energy waste. This certification means it operates at a minimum of 87% efficiency at 20% and 100% of rated load, ultimately saving on electricity bills over time. In contrast, the CanaKit does not specify an efficiency rating but is designed for specific Raspberry Pi applications rather than general power efficiency.

Noise Levels

The CanaKit power supply includes a noise filter for added stability, which helps minimize any electrical interference. However, the Rosewill is specifically designed to operate quietly, featuring a 120mm FDB silent fan that enhances cooling performance while keeping noise levels low. This makes the Rosewill a better choice for users sensitive to noise, particularly in home or office environments.

User Experience and Features

CanaKit’s power supply is straightforward and user-friendly, specifically designed for Raspberry Pi users, which simplifies installation and usage. The Rosewill, however, is equipped with advanced features such as optimized thermal control and a comprehensive safety shield that includes six types of protection (OCP/OPP/OTP/OVP/SCP/UCP). These features cater to gamers and PC builders who prioritize safety and performance.

Warranty and Support

The Rosewill VMG 850W comes with a 5-year warranty, providing peace of mind for users investing in a high-end power supply. The length of this warranty reflects the manufacturer's confidence in the product's durability and performance. The CanaKit does not specify a warranty period, which may be a consideration for buyers seeking long-term reliability.

Which should you buy?

Ultimately, the decision between the CanaKit 45W USB-C Power Supply and the Rosewill VMG 850W 80+ Gold hinges on your specific needs. If you are looking for a reliable power supply for a Raspberry Pi 5, the CanaKit offers excellent value at $15.77 and features designed explicitly for that purpose. However, if you require substantial power for a high-performance PC or gaming rig, the Rosewill’s robust capabilities and 850W output justify its higher price of $74.97.
