[SOLVED] New rtx 2060 make my pc shut down

[GingerFox]

Yesterday I got a new RTX 2060 6gb oc (I had GTX 960 4gb before), after installing it I got the drivers update and I tried to play apex legends and rainbow six siege I'm not sure if they are heavy game tho
My pc started to shut down and turn on again, I put a new fan cooling the arctic 34, and now after installing the fan the temps seems fine I didn't saw any spike in the usage now but my computer is still shutting down and I don't know what to do..
my spec: Cpu: Intel core i5 6600k 3.5ghz skylake
Gpu: RTX 2060 windforce 6gb oc
16 ram
supply power: corsair VS 550
Please help me :\
