i had initially built a pc using these parts
i5 6600k
hyper 212 evo
msi gaming m5 motherboard
2x4gb corsair ddr4 @ 2133mhz overclock-able to 2400
evga supernova 750w g2
western digital hard drive 1 tb
ritemaster dvd disc tray
normal keyboard and mouse
wireless internet reciever
used onboard graphics
case: vantage blue led case with 1 stock case fan in it at the front
when i first started using it it would randomly shut off and restart but eventually the problem stopped so i thought it was fine.
after this i added a gpu around 2 months later being a sapphire nitro+ rx 480 factory oc to 1208mhz
and replaced the fans being a corsair af 120 performance and a sp 120 performance with a 4 pin extender cable being used to attach the sp 120 to the motherboard
it initially worked for a few days but would randomly shut off and restart so i regularly felt the psu to see if it was overheating but it was cool air coming out the exhaust
eventually it just stops completely and when i went to power on the psu via the on / off switch a brief clicking noise would happen and then the power button wouldn't work
i left it for a while and then it started working again so i used it but then the same thing happened and the clicking noise happens when you turn it on and the power button doesn't work im unsure whether to get a new psu or if its my entire pc that is dead :/

what's your home A/C voltage? looks like ampere drought issue, down clock CPU at 20X100 and GPU at 60% speed,disable energy saving, if persist, increase until reach stable setting, update latest BIOS and all drivers, reinstall all drivers and patch. I wish someone from MSI explain why we found many of your products have power stability issue.
