I'm super excited because my 9070XT is arriving today, and I'm upgrading from a 3070! However, I've just realized that I have a 750W PSU instead of the 850W I thought I had. I want to make sure this is going to be sufficient for my setup, which includes a 12600K CPU, 4 fans, 1 SATA SSD, and 1 NVMe. I don't plan on overclocking the CPU or GPU, so is 750W adequate?

A 750W PSU should be more than enough for your build. Given the quality of your unit, the Thermal Take Toughpower GF1, you should be fine. Most setups like yours typically draw around 600W, so you shouldn't have any issues at all.
Keep in mind that while you might get away with a 750W PSU, some brands recommend an 850W minimum. Just make sure your PSU is up to the task with power spikes, especially if it's a bit older. It could be worthwhile to look into a newer ATX 3.x model for peace of mind.
I've been running a 9070XT with a 750W PSU for some time, and it hasn’t let me down yet. My setup is similar to yours, and under full load, I'm hitting around 500-570W. But yeah, if you’re really nervous, you could consider getting a higher-rated PSU, especially if you plan on doing more intensive gaming.
Honestly, you're probably safe with 750W, but it might be a good idea to undervolt just a bit to improve efficiency. Even if you don’t face issues, you’ll find that gaming at the higher end of your PSU’s capacity isn’t ideal for long-term performance.
