I'm planning to build a system around an RTX 5080 and have heard concerns about power cables or adapters overheating and melting. I've also seen newer power supplies advertised as having features that help prevent this, but I'm unclear whether the important part is the PSU itself, a newer cable standard, or some kind of power-limiting protection. Would buying a PSU such as the ASUS ROG Strix 1000P Gaming be worthwhile, or would a normal high-quality unit be sufficient?

You probably don’t need anything exotic. Choose a reputable PSU manufacturer, make sure it has enough wattage for the whole system with some headroom, and use the proper cable that comes with the unit.
The newer standard you’re thinking of is ATX 3.1, usually with a native 12V-2x6 high-power GPU connector. It can be a convenient and safer setup than using multiple older adapters, but it isn’t a guarantee against every problem. The connector still needs to be inserted completely and kept free of sharp bends right at the plug. If you already own a good, compatible PSU, replacing it may not be necessary.
Look for a well-reviewed A-tier PSU with sufficient capacity. Around 850W may work depending on the rest of the system, while a 1000W model gives more comfortable overhead for a high-end processor and the 5080. Options such as the ASRock Steel Legend 850W or Montech Century II 1050W can make sense if they’re priced well, but brand reputation, reviews, protections, and the correct connector matter more than a special premium feature.
A quality ATX 3.1 unit with the correct native GPU cable is a sensible choice for a new build, but the main thing is proper connection and adequate capacity rather than paying extra for a particular gaming label.
