Power Supply

A power supply is simply something designed to supply power to a device. Typically this is where you plug into your computer. For notebooks however, power supplies have a different form factor and they are known as power bricks, or AC Adapters. Please consider the Amperage, voltage and output power before you purchase.

A computer power supply, also known as a PSU (power supply unit), is a device that provides power to a computer. It converts the alternating current (AC) power from the electrical outlet into direct current (DC) power that can be used by the computer's components. Here's how to use a computer power supply and what to look for when buying one from CompSource:

  1. Connect the power supply to the electrical outlet: First, plug the power supply's AC cord into an electrical outlet. This will provide power to the power supply.

  2. Connect the power supply to the computer: Most power supplies have a number of connectors that can be used to connect the power supply to the computer's components. These connectors include a main motherboard connector, a processor power connector, and connectors for other components such as the graphics card and hard drive. Refer to your computer's manual or the documentation that came with the power supply to determine which connectors to use.

  3. Turn on the computer: Once you have connected the power supply to the computer and the electrical outlet, you can turn on the computer by pressing the power button.

When purchasing a computer power supply from CompSource, there are a few things to consider:

  1. Compatibility: Make sure the power supply is compatible with your computer's components. This includes ensuring that it has the correct connectors and that it can provide enough power to meet the needs of your system.

  2. Efficiency: Look for a power supply that is rated for high efficiency, as this can help reduce energy consumption and lower your energy bills.

  3. Quality: Purchase a power supply from a reputable manufacturer to ensure that you are getting a high-quality, reliable product.

  4. Warranty: Consider purchasing a power supply that comes with a warranty, as this can provide peace of mind and protect your investment in the event of any issues.

Overall, a computer power supply is an essential component of any computer system and is used to provide power to the computer's components. Purchasing a high-quality, reliable power supply from a reputable retailer like CompSource can help ensure that your computer has a stable and consistent source of power.
