Now you should install the power supply into the case. If you bought a case that already has a power supply installed you will not need to complete this section. The power supply should be slid into the space behind the rectangular cutout. Figure 2-15 shows where the power supply should be placed.

There are four screws that hold most power supplys in place. Once you have slid the power supply in you should fasten each of these screws. When the power supply is installed, the side view will look like Figure 2-16.

Your power supply is now connected. Most cases will require a power connection to power the fans, and other case accessories. Some cases do not have such a connection. For this case, Figure 2-17 shows this connection being made. It is between one of the full-sized ATA cables and the case’s power connector.
