Question GTX 970 LOSING VIDEO DURING GAMES

[BrotaKill]

I have a sudden loss of video during games on a pc here at home, a Ryzen 3 3200g/16GB RAM/GTX 970/Cougar VTE 600W

My attempts at a solution were as follows:

I put the GTX 970 in Kit i5 10400/CX 600w/16 RAM = It worked perfectly
I put the GTX 1660 on the Ryzen 3 3200g/VTE 600w = it worked perfectly
I put the Cougar VTE 600w on the i5 10400 with the GTX 970 = It worked perfectly
I put the CX 600w on the R3/GTX 970 = Lost video in game
I changed the memory and it didn't work either.
That is, the GTX 970 works on my i5 perfectly, and my GTX 1660 works on the Wife's Ryzen 3 3200g.
Just put the GTX 970 with the Ryzen 3 3200g that loses video during the game.

NOTE: During normal use, without playing, no video is lost.

I've already updated drivers, I've changed the operating system, I've even updated the motherboard's bios, a B450m gaming br.
Help-me Pls!

That's rather odd, and something that will be tricky to nail down without a proper load tester/oscilloscope. Do you have access to any good-quality PSUs? It may be the path of least resistance since both PSUs are of questionable quality.

Unfortunately, I don't have access to any other PSUs. This 970 has always worked with an older i5 4460 and the CX600W. And it now works with the i5 10400, both the Corsair CX600W and the VTE600W.
