I'm working with a tight budget and recently picked up some new components for my setup: an i5-14600k processor, a Gigabyte B760M DDR4 motherboard, 32GB of 3200MHz RAM, a 1TB Teamgroup NVMe SSD, and an Intel Arc B580 GPU for about $530. I want to use my old Thermaltake 630W semi-modular PSU (which is about 8-9 years old) from my previous build, where it worked just fine. However, I've heard that older PSUs can potentially damage new components. Should I be concerned about using my old PSU for this new build, or is it okay since I want to save money?

You can definitely use it for now. Just plan to upgrade down the line. If it’s working well now, then go for it! However, don't forget that some PSUs come with long warranties, so check if yours does. If it's reliable and holds up for your current needs, it could save you some cash in the meantime.
Unless you've been pushing it really hard, your old PSU should be fine. I suggest getting a wattmeter to see how much power your system pulls, especially during games. I've found that even under heavy load with high settings, I'm under 500W, which is well within your PSU's limits.
I've used the same PSU for different builds over 13 years without any issues, but I did eventually have to replace it when my new GPU wasn't compatible. If your PSU is from a decent brand, you should be okay for a while. It’s just a waiting game to see how long it lasts!
As long as your PSU has the proper protections, it's unlikely to fry anything—most issues happen with cheap brandless units. Your Thermaltake 630W PSU is likely decent, so I wouldn't stress too much. Just be sure to monitor its performance. If it has a good reputation, you're probably safe to use it a bit longer, but keep an eye out for any signs of failure.
It's pretty rare for an old PSU to fry new components, but it does happen occasionally. If your PSU is still under warranty, I say go ahead and use it. If not, you might want to hold off on your build until you can get a new one. Remember, an old but reliable PSU is usually a better choice than a cheap new one.
I would recommend just getting a new PSU for peace of mind. They're not super expensive, and it's worth the investment to avoid any potential issues with your new parts.
Should I only consider gold-rated PSUs for the future?
