A couple of days ago i installed my new gpu ,gtx 1060, and everything was fine. I downloaded all the correct drivers and then dried some games. I ran csgo and it worked fine. When i tried the Crew all maxed out my pc crashed. I then tested my gpu with occt tester and i had no errors/crashing. When i tested my psu it crashed in 15 seconds. I have a 420 watt no brand bad psu. Should i change a psu to a 550 watt or my gpu is the problem??
Thanks for reading and maybe reply!
 
Solution
Yeah I'd recommend changing the power supply regardless of whether it's the problem (which it's likely to be). A Corsair CX 450M (the gray one, not the green one) would be a decent replacement.
