The black wires should be in the middle, black to black. Remove the connection to the remote power switch at the front of the case. Orientation of the colored wires at this switch is critical. If you remove them, make sure you document well, and during re-assembly plug the computer into a fused surge protector before turning it on this could save your motherboard and components from melting if you've reconnected improperly.

If you're putting the same power supply back, it's better to remove the entire switch and leave the connectors entact. The remote switch on an ATX form factor attaches to the motherboard. Remove the four screws at the back of the case and gently slide the power supply out of the case.

While removing these screws, hold onto the power supply. You don't want it falling into the case. Removing the Motherboard Document and remove all wire attachments to the motherboard. Some of these have Pin 1 designations also. Most cases have a removable panel that the motherboard is attached to.

By removing a couple of screws the panel can be taken off and you can gain much better access to the motherboard. Again, a little investigation can save a lot of trouble. There is usually 2 or 3 screws holding down newer motherboards. Make sure you've got the right ones and remove them. Motherboards sit on plastic or brass standoffs that keep the traces and solder from touching the metal case and grounding out.

Once the screws are removed you can lift the motherboard out. In other cases, the motherboard has to be slid horizontally towards the bottom of the case to unclip the plastic standoffs and then lifted out. Place the motherboard in an antistatic bag.

A small flashlight and a magnifying glass may come in handy, as well as needle nose pliers.

Before you start, make sure you have taken all your ESD precautions. As you continue, make a conscious effort to remain aware of these precautions. The Power Supply A fairly basic installation, just lineup the holes and screw it on. Don't plug it in yet. Remember, the cable going to the remote switch on the front of the case carries volts AC.

The plastic standoffs on the motherboard are to keep the solder-side of the board from touching the metal case and shorting out. Usually, it's better to install the RAM and CPU first to avoid the possibility of flexing the board and cracking solder connections or traces.

Orient the motherboard properly and either clip in, or slide in the standoffs until the mounting screw holes line up. Insert the screws that hold the board in place. The screws need to be snug, but do not twist them into the motherboard. You may be able to connect the power to the system board as you install the tray. A power supply with a baby-AT form factor will have two motherboard connectors P8 and P9.

These connectors are keyed but can be reversed. Make sure the black wires on the two connectors are beside each other.
