User’s Manual 

 

ATX & Micro ATX CASE  

Power Supply 

 

The power supply installed in the case has a single 20-pin power, 6-pin AUX, and 4-pin 
ATX12V connector for the motherboard.  It also has 4 to 6 peripheral and 1 to 2 floppy drive 
connectors.  Some models may have serial ATA and/or fan signal connectors. The power supply 
has a main power switch next to the AC inlet.  Make sure the power has been switched to the ON 
(I) position before the first boot up.  

Motherboard 

 

The brass standoffs have to be installed on the chassis before the motherboard can be installed.  
Make sure all standoffs line up with the motherboard.  The case comes with standard I/O back 
plate.  The back plate can be replaced with the one came with the motherboard.  

Front Panel Connector 

 

The case comes with a standard set of switch and LED connectors.  Please refer to the user’s 
manual for the motherboard for more specific pin layout.  The typical labels for the connectors 
are 

HDD LED

 (hard drive activity), 

POWER LED

 (system on), 

RESET SW

 (reset), and 

POWER SW

 (power on). Some models may have 4-pin peripheral power connector instead 

of 

POWER LED

.  

3.5” and 5.25” Drive Bay 

 

The case has several 3.5” and 5.25” drive bays. The external 3.5” are typically for Floppy 
drives and 5.25” are for CD/DVD ROM devices. The internal 3.5” are for Hard Disk drives.  

Audio Port (see picture below) 

 

The front audio ports allow the user to install front-oriented speaker and microphone jacks for 
easy access.  Not all motherboard will support front audio port access.  Check the motherboard 
specification for more detail.  Although the labels on the audio connectors in the case may be 
different than the motherboard, they all provide the same functions.  Refer to the following chart 
for clarification.
