Hi guys, I have a noob question to ask. I'm currently in the middle of building my first DIY pc, and wanted to do a power on test on my psu last night... EVGA Supernova G3 750w. I connected up my 4 casing fans and started up the power. Everything ran fine, fans were turning on the psu and casing, LEDs lighting up. I turned the main switch off and went to bed. This morning I tried to power up the system again and nothing works. I confirmed there's power from the cable and the switch is on, so what could the problem be? I find it quite difficult to believe a brand new psu could just die overnight like that.
Edit: forgot to mention, I didn't connect up anything else to the psu other than the casing fans.
