I'm currently using an ROG GM700 Gaming Desktop that has an NVIDIA GeForce RTX 5070 Ti with 16GB. After seeing the RTX 5090 in action, I've decided that's the card I want! I'm not looking to completely overhaul my setup; my plan is to just swap out the 5070 Ti for the 5090 and possibly sell the old card. Do I just need to buy the 5090 and a new power supply, or will I need a new GPU mount too?

You’ll definitely need at least a 1000W or a 1050W PSU for the 5090. And keep in mind that the card is pretty heavy, so investing in a sag bracket or a vertical mount is a good idea.
Before you buy the 5090, I'd like to know what power supply unit (PSU) you currently have. If you're using the 5070 Ti, I assume you're running at a higher resolution, and your CPU should handle the 5090 just fine.
Your plan sounds solid! I’m also upgrading to the RTX 5090 from a 4070 Ti SUPER. Just make sure your PSU can handle enough power, ideally around 1000 watts, because the 5090 has a maximum draw of about 575 watts, plus you’ll need to support the CPU and other components.
