Test all the components on the motherboard box and jump it to make sure all the components function.
Step 1: Install the PSU
Start with the PSU, put it into the case. Once it's lined up with the screw holes, lightly hand tighten the screws to make sure that once you tighten them with a screwdriver that they will be tightened evenly throughout.
Step 2: Motherboard Installation
Take the motherboard out of its box and the antistatic bag. Next, lay the motherboard on top of the box and connect all the other components to it and test that they all work. Once you verified that they are all functional, you can go ahead and install the standoffs for the motherboard into the case. After that, insert the I/O shield into the back of the case, being careful not to cut yourself on the thin metal. Then you will slowly lower the motherboard in, lining it all up into the I/O shield first before you start to tighten the screws. Then you can tighten down the screws and you are done with the installation of the motherboard.
Step 3: Install the Memory
Line up the modules with the notch and push with a little force until it clicks in.
Step 4: Front Panel Connectors
Attach the front panel connectors to the motherboard in the specified places. If it comes with a plate for it, connect it to that first.
Step 5: Install the Hard Drive
Attach the bracket to the hard drive if there is one. Insert the driver into the bays and connect the SATA Power and SATA Data cables.
Step 6: Install the Video Card
Open up a slot in the back of the case, slowly lower in the card, screw into the case, and plug in the connectors if needed.
Step 7: Test
Plug into a monitor and test. If it POSTS you were successful.
