Computer is randomly crashing, is it my PSU or Graphics Card?

[forpiltover]

Hello, I recently bought a r9 280x and everything was running fine until yesterday. It crashed on me 3 times out of no where. I have a Corsair 600w PSU, and everything is running fine when I swapped out my Graphics Card and threw in a 260x. Is there any way to know if its a PSU or graphics card issue? Or something else?

have you tried using that 280x on a different pc with a different powersupply? 600 watts is pretty fine for a 280x but in the amd website it says the 280x requires 750 watts minimum. just make sure you use a quality psu for that 280x specially 1 with a good 12v rail.

Unfortunately I do not. Here is my specific PSU. Amazon Link

I can still order replacements on either, and might just do it for both, but I'd really like to know which one is the issue. It seems like I could chalk it up to a PSU problem, but its been running the 260x fine since yesterday and its been running the 280x beautifully for a few weeks.

it says here its tier 3

you could try to take the 280x back to where you bought it so they can run tests on it.

260x and 280x power consumptions are miles away from each other so you can't really compare that.
