I don't know much about PSUs but my PC had recently been giving me issues every time I played a game. My display drivers would crash and recover or sometimes not recover at all and leave me with a black screen. When I tried to turn it on today nothing happened. I did notice my headset flashing on and off when i turned my PSU on. Does it when i flip the switch only and it also does it once every time. So should I RMA or not? BTW my PSU is a Corsair CX600 (Non-modular)
