Hey everyone! I had a conversation recently with someone who told me that I should always hold the power button on my PC after unplugging it from the wall before touching any internal components to avoid electrostatic discharge (ESD). I've been upgrading my PC for quite a while now, and I've never done this. Is it really harmful if I don't? I stay off carpets, have my PC on a wooden table, and I touch the case several times before touching any components to discharge myself. But I still wonder if not holding the power button can lead to ESD issues. I know power supply units (PSUs) have safety features, but do these work when the power is off? I'd love to hear your thoughts on this!

What you really need to worry about is working on the PSU since the capacitors can hold a dangerous charge. Just being cautious when handling internal components is a good practice, but ESD isn’t something you have to overthink as long as you're following basic precautions like unplugging the power and grounding yourself by touching the metal frame first.
Honestly, don’t worry too much about it. Just make sure to turn off the PSU and unplug it before you start working. Pressing the power button a couple of times can help release any remaining charge in the system, but it’s not strictly necessary. I personally wear ESD gloves mainly for better grip and to avoid fingerprints on my components.
No, you’re fine! I’ve built and upgraded PCs for over 30 years without ever holding the power button, and I’ve never had a problem.
Exactly! I remember back in the day, I once fried a stereo system with static, so I get the caution. Better safe than sorry!
