My pc shuts down

[marcus_59]

My pc shuts down when i play heavy games like fallout 4 with the high texture dlc and witcher3.

Specs:

I5 4430
Rx480 sapphire nitro+ OC 8gb
Gigbyte ultra durable ds3h
500w corsair psu
8gb ddr3 hyperx ram

My pc never goes over 70c temp and i had a asus 6970hd before , that used more watt than my rx480 does without any problems.

Probably a power supply issue. I suggest RMA-ing yours, then selling and replacing it with a better one.

But i used to have a asus 6970hd for a few weeks ago that worked perfectly with the psu.
