Pyramid Desktop Bench Power Supply vs CORSAIR SF850

Introduction to Power Supplies

Power supplies are essential components for any electronic setup, providing the necessary energy to power devices efficiently. In this comparison, we will explore two distinct power supply options: the Pyramid Desktop Bench Power Supply and the CORSAIR SF850. While both serve the purpose of delivering power, they cater to different user needs and environments. The Pyramid is priced at C$70.78, while the CORSAIR comes in at a significantly higher C$279.99.

Design and Build Quality

When it comes to design and build quality, the Pyramid Desktop Bench Power Supply features a rugged housing construction suitable for benchtop or desktop placement. It has a compact design that allows for easy integration into workspaces. In contrast, the CORSAIR SF850 boasts an SFX form-factor, making it ideal for small-form-factor PCs. It is designed for high-density setups yet maintains a sleek appearance. The SF850 uses high-quality 105°C rated Japanese capacitors, ensuring reliability, which is critical for high-performance systems.

Power Output and Efficiency

The Pyramid Desktop Bench Power Supply offers a consistent 13.8V DC output with a maximum current of 12 amps, catering mainly to hobbyists and those testing electronic components. Its linear/regulated design ensures a stable power supply, which is crucial in sensitive applications. On the other hand, the CORSAIR SF850 stands out with its 850 watts of output power, rated at 80 PLUS Platinum efficiency. This means it can deliver high power while minimizing wasted energy, making it more suitable for demanding gaming or workstation setups.

Features and Functionality

The Pyramid power supply is equipped with a USB charge port and universal screw connection terminals, allowing it to cater to a wide array of devices from cellular phones to radios. It also includes built-in short-circuit protection and a cooling fan, enhancing safety and performance during operation. In contrast, the CORSAIR SF850 features fully modular Type-5 Micro-Fit PSU connectors, enabling flexible cabling that aids in tidy cable management. This feature is particularly beneficial in compact builds, where space is at a premium.

Cooling Systems

Cooling is a vital aspect of power supply performance, and both units tackle this differently. The Pyramid includes a built-in cooling fan to prevent overheating, which is necessary for continuous operation under load. The SF850, however, is equipped with a 92mm PWM cooling fan that offers powerful cooling while maintaining low noise levels, thanks to its fluid dynamic bearing design. This means that while both units focus on cooling, the CORSAIR provides a more advanced solution aimed at high-performance scenarios.

Target Audience and Use Cases

The Pyramid Desktop Bench Power Supply is primarily aimed at hobbyists, engineers, and those who require a reliable power source for testing devices in a lab environment. Its lower price point of C$70.78 makes it accessible for casual users or educational purposes. Conversely, the CORSAIR SF850 targets gamers and professionals who need robust power for high-performance setups. The higher price of C$279.99 reflects its capabilities and reliability required in demanding computing tasks.

Price Comparison

The price difference between the two power supplies is substantial, with the Pyramid costing C$70.78 and the CORSAIR SF850 at C$279.99. This significant gap reflects the differences in their target markets and functionalities. The Pyramid offers great value for those needing basic power supply features, while the CORSAIR justifies its higher price with advanced capabilities and efficiency tailored for high-performance applications.

Which should you buy?

Choosing between the Pyramid Desktop Bench Power Supply and the CORSAIR SF850 ultimately depends on your specific needs. If you are a hobbyist or require a simple power supply for testing devices, the Pyramid offers excellent functionality at a budget-friendly price of C$70.78. However, if you are a gamer or a professional needing high reliability and efficiency for a powerful workstation, the CORSAIR SF850, though priced at C$279.99, provides the features and performance necessary for demanding tasks. Assess your requirements carefully to make the best choice for your setup.
