I'm considering whether I should buy a 1000W power supply unit (PSU) for my setup that peaks at around 500W. Is spending extra on a higher wattage PSU a waste, or will it actually contribute to better longevity and efficiency for my components?

I think a 1000W power supply could feel like overkill if most of your usage revolves around 500W. These PSUs do degrade over time and you might not even max them out. If you're planning on sticking with your current setup, something around 700W would be a smart move without being wasteful. Plus, keep an eye on efficiency ratings, which tend to peak at around the 80% load mark.
Honestly, I think getting a 1000W PSU isn't a bad move if you can afford it, especially if it's from a good brand like Seasonic. I've had mine for over a decade and it's still kicking strong through multiple builds. The quality matters more than just the wattage. If you're planning to stick with your setup for a while, investing in a solid PSU can pay off in the long run.
In my experience, aiming for at least 150W headroom is good practice. It's crucial to consider the PSU's quality and connectivity as well. A high wattage PSU that's not up to standard or lacks the right connectors is just bad news. So if a 1000W PSU is on sale, and you'll be able to upgrade later, it might still be worth considering.
Going for something like 650-750W would be perfectly fine if you're only pulling 500W. Plus, you're right that going too big can be a waste. Many PSUs are most efficient around 50-60% load, but a bit higher isn't a huge deal. If you plan to upgrade in the future, having headroom is nice, but make sure to get a reputable brand.
