2Pack 24V/12V to 5V 5A Power Buck Converter 12V to 5V DC-DC Power Down Module Po vs JUSTOP Black 700W Power Supply Unit ATX PSU With 120MM Quiet Fan

Overview of the Products

The 2Pack 24V/12V to 5V 5A Power Buck Converter by Voltrique and the JUSTOP Black 700W Power Supply Unit are both designed to supply power effectively, but they cater to very different needs and applications. The Voltrique unit is priced at £6.49, making it an economical choice for specific electronic devices, while the JUSTOP power supply is priced significantly higher at £29.95, aimed at providing robust power for desktop PC builds.

Applications and Usability

The Voltrique power converter is ideal for users looking to step down voltage from 12V or 24V sources to a stable 5V output, making it versatile for charging various devices such as smartphones and tablets. It features a compact design, measuring only 63 × 27 × 10mm, allowing for easy integration into DIY projects or mobile uses. In contrast, the JUSTOP power supply caters primarily to desktop PCs, featuring multiple connectors designed for various components like motherboards and graphics cards. It provides a total output of 700W, which is essential for high-performance systems.

Compatibility

The Voltrique unit excels in compatibility with a wide range of devices, supporting input voltage from 9V to 36V. This allows it to adapt to diverse charging scenarios, including those for both Android and iOS devices. It incorporates a fast charging recognition chip to optimise power delivery. On the other hand, the JUSTOP power supply is designed according to ATX standards, which guarantees compatibility with most desktop systems. Its single 8-Pin (4+4) 12V rail enhances stability, making it a reliable choice for powering various CPUs and motherboards.

Safety Features

Safety is crucial in power supplies, and both products offer important protective features. The Voltrique converter includes anti-static packaging to protect against static interference during transport and use. While it does not explicitly mention overcurrent or overheating protection, its design provides stable performance under defined conditions. The JUSTOP power supply, however, is more robust in this regard, featuring multiple protective mechanisms such as over voltage protection, short circuit protection, and thermal overload cut-off. This extensive safety framework makes it a more secure option for users concerned about electrical safety.

Efficiency and Performance

The efficiency of the Voltrique converter is highlighted by its ability to provide variable output based on input voltage—up to 6A at lower voltages and down to 3.5A at the highest input. This versatility ensures that devices receive adequate power without wasting energy. The JUSTOP power supply boasts a minimum efficiency of 70%, which is adequate for most desktop applications, but it lacks the dynamic adjustment seen in the Voltrique unit. This might make the latter a more efficient option for specific low-power devices.

Noise Levels

When considering noise output, the Voltrique converter operates silently as it does not have any active cooling components. This makes it well-suited for applications where noise is a critical factor, such as in quiet workspaces or portable setups. In contrast, the JUSTOP power supply features a 120mm cooling fan designed to keep temperatures low. Although this ensures operational stability during high loads, it also generates noise, reported at 40dBA. For those sensitive to sound, the Voltrique might be the more appealing choice.

Installation and Integration

The Voltrique power converter is straightforward to install, with a plug-and-play design that includes various ports and terminals for different applications. Its compact size further simplifies integration into electronic projects, making it suitable for users who may not have advanced technical expertise. In contrast, the JUSTOP power supply requires a more involved installation process, typical of ATX power supplies, and is best suited for users familiar with building or upgrading PCs. The extensive cabling provided with the JUSTOP unit, while beneficial for flexibility, may also add complexity to installation.

Which should you buy?

Ultimately, the choice between the Voltrique 2Pack 24V/12V to 5V Power Buck Converter and the JUSTOP Black 700W Power Supply Unit depends on your specific needs. If you require a low-cost, efficient solution for charging smaller devices in a compact form factor, the Voltrique converter at £6.49 is the clear winner. However, for those building or upgrading a desktop PC that requires substantial power, the JUSTOP power supply, with its robust 700W output and multiple protective features, is worth the £29.95 investment. Each product serves its purpose well, but they cater to distinctly different applications.
