Question Second opinion: bad video card?

[noise_tank]

A few days ago, we had a couple blackouts, and afterwards my computer would not power on. Swapped the PSU with a known working one, still would not power on. I assumed the about decade old motherboard finally gave up the ghost, and I went shopping to build a new PC.

The only components I reused were the dvd drive, my two extra hard drives that I use for games, and the video card (as it was only about 5 months old).

Now that I've got everything set up and running again, I started trying to do some gaming, but am having issues. I've tested in both Warframe and Overwatch with various settings and get the same problem: the screen blacks out for 3-5 seconds at a time, then comes back for maybe 5-10 seconds and this cycle repeats. While the screen is black, you can hear the audio playing like normal. The blackout is a full screen, even if I'm running the game in a window less than my full screen resolution.

Am I safe to say that the video card was probably damaged in some way from the power outages?

What was your previous PSU make and model?
If it was a cheap / poor quality unit, then it is more likely that the power outage has caused the PSU to damage the GPU.

If you have built an entirely new rig asides GPU, and HDD (opticals can be ignored really) - then it is more than likely GPU if it is graphical problems.

Wasn't a cheap brand PSU: Corsair RM850x that was only a couple months old. I don't know if that PSU actually went dead or not, I didn't feel like risking it with brand new components. I bought another of the same model to go in the new build and have left the questionable one out until I decide what to do with it.
