I'm planning to buy a 9070XT GPU since it's on sale, and I'm building a new system in January. The GPU will arrive before the rest of my components. I'm wondering if I can use the 9070XT with a 650W power supply until my system is fully built. Will this setup crash due to power spikes, and is there a risk of damaging any components? Also, can I undervolt the GPU to make it work temporarily?

You'll likely be running on the edge with a 650W PSU. The 9070XT is quite demanding, and you could experience system crashes under load. If you're spending a lot on a GPU, why not invest in a quality 850W power supply? It would be a safer choice.
Every time you demand full power, your PC is likely to shut down. You'll hear a click from the PSU indicating it can't supply enough power. It’s risky to run it like that.
If your PSU is reliable and your other components aren't power-hungry, you might be okay. Just remember that PSUs work best below 80-90% load; running close to max can lead to issues.
You can use the 9070XT with a 650W PSU for basic tasks, but you might run into problems during heavier use. AMD's minimum recommendation is 750W, and you'll probably find out what 'too much load' means the hard way if you push it. Investing in a good PSU is crucial for the safety and longevity of your system.
AMD recommends a minimum of 750W for the 9070XT. While it might technically work with a 650W PSU, I wouldn't advise it. If your PSU isn't high quality, it could shut down under heavy load, which could be problematic.
Totally! Running a PSU at high load isn't ideal, you might face higher energy consumption too.
