I'm looking to upgrade my GPU and currently have an RTX 3070 Ti, but I'm considering switching to a 5070 Ti. I want to know if my Corsair RM750X 750W v2 power supply will be sufficient to support the new graphics card since I've seen mixed opinions on this topic online. For reference, the specific card I'm thinking of is the Gigabyte GeForce RTX 5070 Ti Windforce OC. Thanks for your help!

Probably. Just give me your PC specs, including all the drives, and we can better calculate the headroom.
Your CPU plays a role in this too. A 750W supply should work as long as other parts aren’t pulling too much power. It’s the minimum I would recommend.
Most likely yes, but make sure to consider your other components when you’re calculating wattage.
It really depends on the rest of your setup. A good idea is to plug your components into PC Part Picker, which will give you the total wattage. Ideally, you want about 150W of headroom to play it safe, but you might be okay with your current setup.
Yes, 750W is definitely enough. You don’t need to worry!
Yeah, you're good! A 750W power supply is actually the recommended wattage for running the 5070 Ti, so you should be perfectly fine.
In my experience, I run a 5070 Ti along with a 9800X3D on a 750W PSU and haven’t encountered any issues. If you're considering future upgrades, you might want to opt for an 850W PSU for a bit of extra headroom.
If you're buying new, I'd suggest getting an 850W unit so you have more flexibility for future components. I use a 5070 Ti with an 850W PSU myself, and it's been solid—plus it has a native 12V connector!
