2.10 Replacing the power supply unit
Replace the power supply unit (PSU) after installing the system components and
reconnecting the cables.
To replace the PSU:
1. If necessary, connect the 4-pin
12V power plug to the ATX12V
connector on the motherboard.
2. If necessary, connect the 24-pin
ATX power plug to the ATXPWR
connector on the motherboard.
3. Connect the optical drive power
connector.
4. Lift the PSU in the direction of
the arrow until it properly ts in
place.
5. Secure the PSU with the
screws you removed earlier.
Make sure the PSU cables do not interfere with the CPU and/or chassis fans.
Voltage selector
The PSU has a 115 V/230 V voltage selector switch
located beside the power connector. Use this switch to
select the appropriate system input voltage according
to the voltage supply in your area.
If the voltage supply in your area is 100-127 V, set the
switch to 115 V.
If the voltage supply in your area is 200-240 V, set the
switch to 230 V.
Setting the switch to 115 V in a 230 V environment will seriously damage the
system!
