Out-of-touch gamer has 3090 problems (self.pcmasterrace)

EDIT: Wow, this was an exercise in humility

Turns out, when i disconnected my PC display cables before the hardware swap, my monitors were still on and swapped inputs from Display Port to HDMI. When I was swapping cables and checking connections, I didn't even think to check that the monitors were set to input the right connection.

I'll be leaving this post up for anyone else in the future who might find themselves in my position. Check your monitors input!

~~A few days ago, I made a post about being gifted a EVGA 3090 RTX from my brother-in-law and was asking for help figuring out what I'd need to upgrade to run the new card from my 1070. Here is a link to that post. Before this week, it had been about seven years since I'd looked into computer hardware, and even at my best-researched I was never super knowledgeable on the subject. You all said that most of my components would be great, but I upgraded my PSU to a Corsair RM1000X 1,000-watt unit.~~

~~Since installing my GPU (Literally fifteen minutes ago), I'm getting no video from any of the outputs. The PC seems to be powering on fine because the lights on my peripherals are working. Just to be clear, the screen doesn't flash and then go black, I'm getting no video at all.~~

~~I followed this video 100% before removing my old GPU. The last thing I did was run a DDU before shutting down the system.~~

Obligatory system specs:

Ryzen 9 5900x CPU
EVGA 3090 RTX GPU
MSI Tomahawk B550 MoBo
32gb RAM
Corsair RM1000X PSU

After reading the first sentence, I was surprised to see this wasn't a "plugged the monitors into the motherboard instead of the GPU" post. I've never seen this one before! Glad everything's working for you

Since there is a new PSU, the question has to be asked: are all the cables connected to the GPU? 3090 appears to have 2 or 3 cables connecting directly to the GPU. Are those installed?

Look at the existing hardware: Does installing the 1070 still work? Does the 3090 work in another system? Is the monitor plugged into the new video card?

Thanks for commenting! Turns out everything was connected properly, but my monitors switched inputs when I disconnected my PC for the hardware swap and I never caught it

Hehe, it happens.

I spent an evening troubleshooting my audio, reinstalling drivers etc because the L/R channels were reversed

My headphones were backwards...

So... Yea.

Also seemingly the order, make sure the 3 cables are in order.

I'm also not sure if a daisy chain is supported with the 3090? I know I'm getting lucky my with my 3080 being on a daisy chain.
