Hi all, Never had this before, so keen to get some advice and suspicion of causes before I start fiddling. Was just working on my PC when it suddenly cut out on a zoom call - assumed there was a power cut or something, but realised it was just my pc that had cut out. I could see the RAM was still illuminated etc inside, so obviously some current still coming to the MB, so tried checking all the plugs were connected fully - all looked fine. Unplugged the PSU three pin plug in the back of the PC and plugged it back in to doublecheck and got a visible large spark at the back of the PC and a loud pop and tripped electricity on this floor of the house. Scratching my head as to what could actually cause this - strongly suspect I'll need a new PSU (was a be quiet! Pure Power 11 500W 80 Plus Gold Modular Power Supply). Has anyone else had something like this occur before and any advice!
