After doing some maintenance on my pc I reconnect the power cabel and turned my psu on, but when I switched the power button on the lights in room my turned off. I went into my house's fuse box and the fuse was switched off. I switched the fuse box back on and started my pc. It works, but I'm afraid that somthing might have gotten damage. My psu is a corsair rm750x 80+ gold psu.
