We all know pulling the plug on a running PC is bad, bc the operating system could be in a critical process and interrupting it would corrupt the system.
But using a capacitor that holds electric charge couldnt we give the PC a couple of „grace seconds“ where the pc finishes its job and then starts the shutdown process?

You end up needing a really big capacitor
There are already what I’d consider big capacitors in the power supply but they can only give you a fraction of a second to make it through a very brief power disruption
If you want to cover a system that’s running at a mere 35 watts for 5 seconds then you need a capacitor that holds 175 joules. At 500V that would be a 1700 uF capacitor. They make them but they’re about 2 inches in diameter and 4 inches long
If you’re really prone to abrupt power outages then get a UPS, that’s what their meant for and the lead acid battery in there will give significantly longer run time
