I also check if the power supply has certifications like UL, CE, or FCC, which indicate compliance with safety standards.

Size and Mounting Options

Depending on where I plan to use the power supply, I check its physical size and mounting options. Some come with brackets for panel mounting, while others are designed for desktop use. Ensuring it fits my workspace is important.

Efficiency and Heat Management

Higher efficiency means less energy wasted as heat. I look for power supplies with good efficiency ratings to save on energy costs and reduce heat output. I also check if the unit has adequate cooling features like built-in fans or heat sinks.

Connections and Wiring

I pay attention to the type of connectors and wiring options. Some power supplies come with screw terminals, while others might have plug connectors. I choose one that matches my setup for easier installation and maintenance.

Warranty and Customer Support

A warranty gives me confidence in the product’s quality. I prefer power supplies that come with a reasonable warranty period and accessible customer support in case I encounter issues.

Price vs. Performance

Finally, I balance cost with features and quality. While I don’t necessarily go for the cheapest option, I look for a power supply that offers good value for the price, meeting all my requirements without unnecessary extras.
