Computer freezing and then turning off without warning

[Fixleader]

Hello everyone!

Yesterday i bought AMD FX-8370 with wraith cooling, along side AMD RX-560 2GB DDR5 and 8GB DDR3 to use with my 4GB stick
First I couldn't get the computer to boot because of outdated BIOS.
But i flashed the updated version of BIOS on my M5A88-V EVO motherboard, so it worked after that.

After a little while the computer just rebooted itself and i had the ASUS anti-surge saying my PSU is unstable.

My current PSU is 560Watts

My question is should i upgrade the PSU, and if so which should i take?

Your PSU is most likely at the end of its lifetime, and the upgrade just pushed it over into instability.
Yes you should absolutely get a PSU as unstable psu can threaten all other components. As far as upgrading, I'd go for something like 650 or 750W to be safe but more importantly, something of good quality. This is a nice list to stick to of tried/tested/true models:

Stick to tier one or two.

What's the exact make and model of your PSU? Wattage isn't an indication of quality and 560W is a somewhat unusual number.
