What precautions should i take with a bad PSU?

So I accidentally bought a Mars Gaming MPB650SI PSU before realizing it doesnt exactly have bad reviews . My system is a 6600 XT + Ryzen 5 5600X, I dont plan on overclocking, and I plan to replace the PSU in about 6–8 months.

Until then, what precautions should I take to avoid issues?
