Chapter 2: Basic installation

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.

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!
