Preparation.
Remove the screws that hold the covers in place at the bottom of the case and at the back. Push the covers aside and remove them. Make sure your components match the SX2 7.5L chassis specification. If you have doubts, you can contact us for help.
 

Installation of the Power Supply Unit.
The case is compatible with the SFX and SFX-L PSU (Power Supply Unit) formats (when installing the SFX-L PSU format, you will not be able to install LCS*, see point 4) If your PSU has a modular cable connection, connect only those that are necessary. Unscrew the screws securing the bracket to the PSU, screw this bracket to the PSU using the screws from the CDK (case delivery kit) or the PSU. Connect the power cable to the C14 socket on the PSU, then insert the PSU with the mount into the case and screw it into place. There are two types of internal power cable:

-Type A-
​Silverstone: SX1000; SX800-LTI; SX750; SX600-G; NJ450-SXL; ST45SF-G
Chieftec: Compact series; SFX-350BS-L; SFX-500GD-C
Seasonic Focus;
Lian-Li
Thermaltake Toughpower 
Enermax
Fractal Design ION

-Type B- 
Silverstone: SX700-PT; SX700-LPT; SX700-G; SX650-G; SX550; SX500-G; SX500-LG; SX450-B; ST45SF; SX300-B; ST30SF

Installing a 92 mm fan.
Skip this step if you do not plan to mount the case fan on top. Several fans can be installed in the case. One above the motherboard, measuring 92x92x14mm, the other under the motherboard (see point 5). Before installation, screw the grill to the fans. Put the fan inside the case and screw it.
 

Installation of SRO.
Skip this step if you plan to use an air cooler. In this case, you can install a compact LCS (Liquid Cooling System) for the CPU, for example Asetec 645LT. Install the radiator with a 92mm slim fan (use the grill to protect the fan) under the SFX format PSU (the SFX-L format is NOT compatible!) For a more convenient installation of the radiator, unscrew the screws from the front and bottom of the case. Carefully separate the housing elements, install the radiator and fix it. Fold the case and tighten the screws.
 

Installing the motherboard.
Read the instructions for your motherboard (hereafter MB). For your convenience, install everything you need on it (CPU, CPU cooler, RAM, NVMe drive, if used. Follow the instructions of the component manufacturer). Install the plug in the case, if it is not fixed on the motherboard, before mounting the MB. Screw the MB to the case using the screws from the CDK and a magnetic screwdriver. Connect the PCIe riser cable to the MB if you plan to install a video card.
 

Installation of 2.5" drives.
Skip this step if you do not plan to use a 2.5" drive. Connect the interface to the drive. Screw the brass racks to the drive, and then screw it to the case. Also, instead of the 2.5" drive, a 92x92mm fan can be installed in the case. We recommend installing a grill on top of the fan to prevent wires from getting into the fan.
 

Video card installation.
Skip this step if you do not plan to use the Video card.  Connect the additional power supply of the video card, if provided by the video card manufacturer (see the installation instructions for your video card in the video card delivery kit) before installing it. Insert the video card into the case, install the cable in the PCIe x16 riser connector as far as it will go. Push the loop back. Fasten the video card with screws using a magnetic screwdriver.
 

Final Assembly.
Carefully route all cables using nylon cable ties from the CDK. Check that all cables are connected, including the Power button cable. Start the computer and make sure that all the fans can work freely and nothing is obstructing them. Now you can install the covers by screwing them.
