Do I need to worry about static electricity when building a PC?

For most people, normal clothing and a little common sense are enough. Avoid thick carpet, synthetic clothing that builds up static, and deliberately shuffling your feet. Touching the metal case before handling the motherboard, memory, or other parts is usually all the extra protection you need.

A simple precaution is to install the power supply in the case, plug it into the wall, and leave its power switch turned off. The case will then be grounded, so touching the metal chassis before handling components helps discharge any static. You can also touch the case periodically while working.

You definitely don’t need to build the PC naked. Static damage is relatively uncommon, especially if you avoid rubbing your feet on carpet or wearing wool socks. Work on a wood, glass, or plastic table, and place the motherboard on top of its box while installing parts.
