I'm looking into power cables for my PC and have noticed that the manufacturer, BeQuiet, offers replacement 20+4-pin ATX power cables that are listed as having 18/20/22 AWG. I'm a bit confused about this and have a few questions: 1. What is the gauge of these cables? 2. What is the gauge of the original cables that came with my PSU? 3. Would it be better to use 16 AWG cable extensions from other brands like EZDIY-FAB or Asia Horse instead of going with BeQuiet's replacement cables? My main goal is to improve the aesthetics of my setup, but I'm worried about potential warranty issues or overheating problems. Any advice would be appreciated!

Honestly, it sounds like you're stressing over this a bit too much. Typically, the OEM cables are pretty reliable. If BeQuiet's selling cables rated at 18 AWG, chances are the original cables in your PSU are similar. Feel free to use any extensions you like – just don't overthink the gauge too much!

Thanks for the reassurance! I’ve read so many mixed opinions about cable extensions, it's good to hear that the stock cables are usually fine.
