A few months ago I made an upgrade from 2070 super to 4090. Along with it I upgraded my PSU from 850x to 1000e to support the 4090.
Immediately, I have this problem, where for some applications (not all graphic intensive ones),
the monitor, keyboard and mouse would shut off as if the computer had been shut down, but the PC fan, lights would stay on. I then cannot power down the PC. I need to flip the PSU for at least 10 seconds, before flipping it back on. If I flip the PSU back on too early, the PC automatically turns back on, but still no reponse from the monitor, keyboard or mouse.
I have been working with Nvidia and corsair customer support, to no avail. Here is where the problem gets stranger. In my testing, when I put back on both the 2070 super and 850x, I would have no problem. However, if I use the old 2070S with the new 1000e PSU. I would have the issue. Similarly, if I use the new 4090 with the old 850x. I would also have the issue. Corsairs RME the PSU, and I have the exact same issue with the new PSU.
I can only imagine that this is a PSU/GPU/MB (MB is b450 tomahawk max) problem. However the MB is not new, and again it works perfectly with the old 2070S and old 850x. I also do not have another motherboard I can swap & test with.
I need help from the gurus of this forum.
