Forgot that the PSU I'm using to power some stuff was active (I usually switch off the power strip). Shocked the hell out of myself. Felt like my entire arm was vibrating. Lmao
Oh I know that feeling. Tingly sensation, I did it once while I was replacing a power supply unit to a lower wattage one whilst optimization my PC to run at full efficiency but somehow there was still charge in the old one. Scared the living shit outta me, thought I was going to die
