Depending on the configuration of the machine, computers can draw considerable amounts of power, even when not performing system-intensive tasks. By building a computer from energy-efficient components, you can make a machine that will suit your needs and is more environmentally friendly.
Part Selection
Step 1
Review the CPUs currently available for purchase and create a list that will meet your processing requirements. Compare the wattage requirements of each CPU option to determine which is the most energy-efficient.
Step 2
Select a motherboard that is compatible with your selected processor and comes equipped with integrated video and support for DDR2 memory sticks.
Step 3
Select a hard drive that meets your storage needs and has low power requirements. If selecting a conventional hard drive, choose one with a rotation speed of 5400 rpm. Select an optical drive that meets your media needs and has low power requirements.
Step 4
Add up the power requirements of each of your selected components. Select a power supply capable of providing the necessary power. Make sure the power supply is certified as meeting the "80 Plus" requirements in order to ensure maximum energy efficiency.
Step 5
Select a case large enough to hold all your selected components. Alternatively, recycle an old case from an obsolete computer.
Assembly
Step 1
Remove the screws securing the side panel of the computer case in place. Remove the side panel and set it aside. Insert the power supply into the bracket located on the rear panel of the computer case such that the power switch will be accessible from the rear of the case. Screw the power supply onto the case.
Step 2
Open the processor locking mechanism on the motherboard. Insert the processor into the matching socket on the motherboard, then close the locking mechanism. Apply a small amount of thermal paste to the top of the processor, then place the heat sink onto the processor. Secure the heat sink to the motherboard.
Step 3
Insert the motherboard into the computer case and position it such that the interface ports are accessible from the rear panel of the case. Align the holes in the motherboard with the screw brackets on the case. Insert screws into the holes, and tighten the screws until the motherboard is secure.
Step 4
Locate the memory module sockets. Push apart the clips located at either end of the sockets. Insert the memory modules into the sockets, then push down on the top edge of the modules until the clips snap into place.
Step 5
Insert the hard drive into one of the drive bays located near the front of the computer case such that the connectors located at the rear of the drive face the interior of the case. Insert screws into the sides of the drive bay and secure the hard drive in place. Install the optical drive in a similar manner.
Step 6
Connect the cables leading from the power supply to the matching sockets located on the motherboard, hard drive and optical drive. Connect the interface cables to the appropriate socket on the motherboard. Use the remaining end of the cables to connect the hard drive and optical drive to the motherboard.
Step 7
Connect the cables leading from the computer case to the appropriate pins on the motherboard. Inspect the diagram next to the pins to determine where to connect each cable. Replace the side panel of the computer case, and use the previously removed screws to secure the panel back into place.
Tips and Warnings
- If desired, you can include options such as a video card, sound card and additional drives. However, each additional component will increase the energy requirements of your system. Whenever possible, eliminate part options that are not labeled "lead-free." Solid state hard drives and laptop hard drives are often more energy-efficient than conventional hard drives, however, they may also prove too expensive, depending on your budget and storage requirements.
