I'm looking to swap out my power supply unit (PSU) and I'd prefer not to deal with redoing all the cables. Is it safe to just change the PSU and keep using the old PSU's cable connectors? The old PSU is ATX3.0, and the new one is ATX3.1, but they're from different brands. Will this work?

You definitely shouldn't mix cables from different PSUs, even if they look similar. If the PSU brands don't match exactly, you're asking for trouble. Just stick to the cables that came with your new unit.
It's not safe to reuse cables from a different PSU—trust me, you could damage your entire setup. Each PSU is designed with specific cables, and using cables from a different brand or model can cause serious issues. It's best to use the cables that come with your new PSU.
I get that re-cabling sounds annoying, but it's important. Each PSU has its own pinout and using a different one can fry everything. I know it seems like a hassle, but for your system's safety, it's worth it to swap out the cables.
Honestly, you'd be risking a lot by trying to use old cables. While some brands like Corsair allow for cable reuse within the same type, that's not the case across different brands. Better safe than sorry—use the new cables!
