It's in a 3 year old HP computer. Do you think it would need to be replaced with like a seasonic PSU?
Hi - You have an hd7970, not a sound strategy to risk that level gpu
with a low end psu with Chinese caps, etc. You are playing with fire.
Your sys tdp with that gpu is approx 335w without oc, I suggest
a quality 550w (no harm in more) psu.
And yes, you were right on Seasonic or other quality brands.
