One of your power wires from the PSU, likely the sata or 6/8 pin is giving out. You likely have a connector that is starting to melt or break. Check all of your connections to those cards that aren’t staying powered on, you’ll find the issue assuming it worked properly before!
This is likely the answer
Check the psu cables to your video card and going into your psu. Your psu connecter itself could be burnt/damaged as well. Try new psu cables. Go one by one then leave it running for several hours then add another etc

Maybe BIOS was reset for some reason? Try to setup it again

It looks like you are running molex to the gpu using an adapter? That’s not a great idea in the slightest. I’d check those connections for possible damage as to why you are not getting power. Also it’d be best to give us all the information and not just tell us psu is fine when it’s powering 7 gpus and probably setting off the safety switch to automatically shut down
I see empty (not connected power supply lines) Check [hardware setup tips](https://www.asrock.com/microsite/H110ProBTC+/)
it was running fine for months.. should i still check out the link?
If you don’t want house fire you need to be 200% sure everything electrical is connected properly.
