Yes, you can temporarily use two power supplies.

Hi, your question is clear. You're checking whether your old 450W PSU might be the cause of GPU problems. It's safe to test the GPU separately using that PSU to see if crashes persist. Just make sure the PSU is stable and capable of handling the load before proceeding.
Yes, you can if you understand what you're doing. Or not if you're unsure. I tested a dual PSU for a while without a single high-wattage unit and it worked. It depends on the GPU or system and the issue at hand. We could save time and see if a better PSU is feasible.
Yes, it's possible. Completed it myself. Safety-wise? Not entirely. I'd avoid doing it every day. For troubleshooting, it seems mostly safe, though. Personally, I've dealt with a PSU that overheated under load and triggered numerous system errors. It also caused the PCIe 8pin to melt.
It might be related to the motherboard as well. Since I don’t have a backup GPU, I’ll attempt the second PSU test first to confirm if the power supply is the issue, then decide the next steps.
