Hey. Long time browser and I usually get most of my info on troubleshooting when I'm stuck from this website, but I've encountered a very serious issue that I need a lot of help with. Normally I can deal with these things myself, but this has me completely stumped and I'm out of ideas.
A few days back, my GPU (an RTX 2070 Super) was under relatively heavy load gaming for maybe an hour, and the computer just completely shut down in the middle of use. Since then, the PC would start, but there was no display, so I took it apart to see how it was inside when it was powered on. The GPU powers on with the fans at 100% and the usual RGB lighting, but still won't display anything.
At one point, smoke came out of the machine and I couldn't find what the cause of it, but apparently the Power LED+ cable may have been the culprit since it disconnected from it's plastic connector. This doesn't seem to have any effect powering the machine on, so I've just left it severed and disconnected the Power LED- cable from the motherboard too. I can't find any signs of anything burnt on the motherboard either (maybe I accidentally knocked the Power LED+ cable out of its socket, and it burnt up that way).
Anyway, I have a spare GPU (an RX Vega 64) and that works in very short bursts. I can sometimes get to the BIOS if I keep rebooting, but the monitor turns black again shortly after reaching it, so I can't even access it to do anything. For a little while, it got as far as the Windows login screen before dying, but it hasn't reached that since two days ago. I've tested the monitor by plugging a laptop into it, and it works fine.
I thought the PCI-E slot was the problem, so I switched the card to the other one (the x8 slot), but I still get the exact same issue with both cards (RTX2070 fans spin 100% with no output; Vega 64 only sometimes giving me very short output, and nothing otherwise). Also, I've tried HDMI and Displayport, and still have the same issue.
I don't have onboard graphics either, so I can't test that out, and I also can't test the cards out on other machines since I don't have access to any.
Here are my specs:
ASUS X470 ROG Crosshair VII Hero
Ryzen 3700x
ASUS ROG Strix GeForce RTX 2070 Super OC Edition
EVGA SuperNOVA 750 G2 80+ GOLD 750W
Here's what else I've tested:
Is it possible for the PSU to be faulty, like it isn't supplying enough power to the GPU(s)? Or maybe I do actually have two broken GPUs?
Sorry this was so long, lol. Thanks for any help/advice!

Here's what else I've tested:
- using only one stick of RAM (no difference)
- using only one hard drive (no difference)
- disconnecting all hard drives just to see if I could at least get a boot error on screen (no difference)
