I'm planning to build a system with an RTX 5070 Ti and a Ryzen 7 9800X3D. I already have a be quiet! Pure Power 13 M rated at 750W, and the listed recommendation says that should be enough for this combination. I won't be overclocking, but I'm wondering whether it's worth upgrading for additional headroom, especially to avoid excessive power draw or PSU wear.

The Pure Power 13 M is a good-quality PSU, and 750W is enough for this build. Unless you’re planning substantial overclocking or adding a lot of power-hungry hardware, there’s no practical reason to replace it.
750W should be completely fine. The manufacturer’s recommended wattage already includes a reasonable amount of headroom, so you don’t need to add another large buffer on top of that for a stock system.
