Power Supply - AC - DC Adapter

AC to DC adapter provides stable DC power to the intended device from an unregulated AC mains supply. Adapters are essential because most of the electronic components in the computer use DC power. Without an AC/DC adapter, most of the technological milestones we enjoy today might not have been possible.

Use the Right AC to DC Adapter

One of the mistakes that many users make is thinking that adapters are universal. They may look alike in form factor and have the same output power rating, but it still remains a bad idea to use just any adapter. When shopping for a new Ac to DC adapter, you need to check the device it was designed for and use it just for that purpose. For example, the Cisco 48V power supply is an AC/DC adapter specifically for Cisco Aironet Wireless Access Point models, and PWR RGD Proprietary Power Supply is for Cisco Industrial Ethernet 5000 Series.

Any adapter can just work fine, but it slowly kills your computer or device. The components inside the computer have rated voltage, current, and lifespan at rated parameters. If any of them is exceeded, then the service life of the lifespan can be significantly reduced.

Very Efficient Power Supply

When shopping for a new AC DC Adapter, you need to be keen on its efficiency. You don't need to end up with a power supply that will escalate the heating problem in the server system and increase the utility bills. Also, consider the form factor if it is to be enclosed in your computer casing. It must fit and not block the ventilation louvers, usually on the sides of the case.

An efficient power supply translates to less heating, as most of the input power is converted to output power for your system. However, you have to spend a little more to get such an efficient power supply. But it is better to spend once than paying high utility bills monthly.
