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 fits
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!
