These products serve different purposes within a computer setup, with the SinLoon providing an external power switch and the JUSTOP delivering power supply to the system.

Design and Build Quality

The design of the SinLoon power switch is focused on user convenience, featuring a 1.8M cable that allows for flexible placement. This makes it easy to install in various locations, whether at home, in an office, or in gaming setups. Its construction combines copper, plastic, and ABS shell materials, ensuring durability and functionality.

On the other hand, the JUSTOP PSU is built to provide reliable power with safety in mind. It includes a 120mm cooling fan to maintain optimal operating temperatures, which is essential for performance and longevity. The PSU is certified by several safety agencies, including UKCA, CE, FCC, UL, and TUV, ensuring it meets high safety standards. While the SinLoon focuses on user experience, the JUSTOP prioritises safety and efficiency in design.

Functionality

The SinLoon power switch offers a unique functionality by allowing users to install both an external and original power button simultaneously. This is facilitated through the inclusion of splitters, enabling users to retain the original on/off function while also utilising the new switch for added convenience. The switch is particularly useful for DIY enthusiasts looking to replace damaged components or enhance their computer's usability.

In contrast, the JUSTOP PSU provides the necessary power for a computer system. It features a single 8-pin (4+4 pin) 12V rail, which ensures a stable and safe power output. Additionally, the power supply includes various connectors, such as a 24-pin (20+4) and multiple SATA connectors, making it versatile for different setups. While the SinLoon enhances user interaction, the JUSTOP focuses on delivering stable and reliable power.

Performance

When it comes to performance, the SinLoon power switch is designed for easy installation and operation.

Furthermore, the option to disconnect the LED terminals if not needed adds an extra layer of user control.

The JUSTOP PSU stands out with its array of safety features. It incorporates over voltage protection, over power protection, short circuit protection, and thermal overload cut-off protection. These features collectively ensure the safety of both the PSU and the connected components, making it a trustworthy option for users who are concerned about potential electrical hazards.

Compatibility

The ease of installation and the ability to use both the original and external power buttons justify the cost, making it a worthwhile investment for those who want a more accessible power solution.

Conversely, the JUSTOP PSU, priced at £32.95, provides a robust power supply solution for users with more demanding needs. Given its 750W capacity and safety certifications, the price reflects the quality and reliability it offers. For gamers and professionals requiring stable power for high-performance components, the investment in the JUSTOP PSU is justified.
