Problem after upgrading CPU and adding SSD

[xPiKe]

Hello. So 2 days ago i bought a new CPU AMD FX8350 and a Kingston 480gb ssd. All wen't well after i put them in so i tried to play a game and my pc crashed after only a few minutes. This happened several times until i decided to install new windows on the SSD to check if that's the culprit. So i did that and the same thing happened but after a longer time than a few minutes. I'm thinking it could be the power supply because i made a stress test on the cpu, gpu and both passed it and when i tested the psu my pc crashed after a few seconds after i started the test. Any thoughts? Let me know if my pc specs are needed and i will add them here. Thank you in advance!

What power supply do you have? What CPU cooler do you have?

^{PSU i can't remember the brand but i know it has 500w max power and wraith cooler that comes with the cpu}

the name of psu is aqprox and i never had any problem with it before the upgrade. but i had a amd athlon cpu before

Thank you for the answers. I wanted to make sure before i tried to refund them. Any idea how i can get around this so i can play some games before buying a new PSU? I tried to lower the max processor usage from Power Management to 60% but it still crashes after a while. Also, what kind of PSU should i look into buying?
