I'm considering an upgrade from my RX 7800 XT to an NVIDIA GPU, specifically the RTX 5080. I have an Intel i5-14600KF and currently, I've been looking at the 5070 Ti, which I've heard is well-suited for my system. However, I've noticed that the power usage of the 5080 is quite similar to the 5070 Ti. Given that I have a Corsair RM750 80 Gold power supply, I'm wondering if I should take the plunge and go for the 5080 or stick with the 5070 Ti instead.

Be aware that you might need a Corsair 2 x 8 to 12VHPWR cable depending on your PSU’s age or if your motherboard uses up a lot of 8 pins. It’s a good precaution if you're going for a more powerful GPU.
I have a 5070 Ti running on a 750W PSU with an Intel 14700 and found that under load it draws just above 500W, so you should be alright with your setup. The 5080 is likely just as efficient, so it should work with your PSU too. Just keep an eye on your total system draw, especially when gaming or benchmarking.
I run a 5080 with a Corsair SF 750 in my small form factor build, and it's been smooth. If you're worried about power usage, consider setting a power limit or undervolting your GPU to increase efficiency. My card runs at 220W under load, and my total system draw is around 400W, which sounds safe for your setup.
