Slide the new power supply into the empty slot vacated by the old PSU, until its back panel is flat against the back wall of the

power supply compartment.
NOTE: There are two keyhole slots in the back wall and one on the front surface of the power supply compartment. The
power supply has three protruding pegs (see figure 3,
Pegs on the Back of the Power Supply
Figure 3.
These pegs must be in the slots on the back wall and front surface of the power supply compartment when you slide
the power supply all the way in. Otherwise, the power supply does not lie flat against the back of the compartment, the
levers cannot lock the PSU in place, and the supply does not function.
If the power supply is in place, its front panel is flush with the front panel of the other power supply. If the new power
supply is not even with the other one, slide the new one out again and lift it up slightly as you slide it in again, until it
touches the back of the compartment.
When the power supply is in position, slide it to the left as far as you can without forcing it.
