Hey everyone! I'm working with a tight budget and just picked up some new parts for my PC build, including an Intel i5-14600K, a Gigabyte B760M DDR4 motherboard, 32GB of RAM, a 1TB TeamGroup NVMe SSD, and an Intel Arc B580 GPU, totaling about $530. However, I'm considering using my old Thermaltake 630W semi-modular PSU from my previous build (which was an old i7 and GTX 970) that's about 8-9 years old. I'm feeling a bit paranoid about whether it's safe to use this PSU with my new components, as I've heard old PSUs can potentially fry new parts. What do you guys think? Should I just go for a new PSU, or is it generally safe to reuse this one?

I used the same PSU across three builds for over 13 years, and it worked perfectly until I got a GPU that needed more power than it could supply. If it’s still functioning well, you're probably okay for now.
Honestly, just get a new PSU. It's not that pricey for the peace of mind it brings, and you’ll avoid headaches down the line.
I found a 15-year-old Seasonic PSU that I trust far more than some newer models out there. Just make sure your PSU has the right protections, and it should be fine. Based on your description, the Thermaltake 630W isn't a bad model. I wouldn't stress too much about it.
Any PSU can potentially fry components if it’s failing or if there are compatibility issues. The real question is whether you can afford a new one. Your current PSU has decent efficiency (87%), so if it's still in good shape, you might be able to use it for a while. Just keep an eye on it and plan for a replacement before long.
Should I only consider gold-rated PSUs then?
It's pretty rare for an old PSU to fry new components. If it still has a warranty, then you're likely in the clear. However, if it doesn't have a warranty anymore, it might be better to hold off on building until you can grab a newer PSU. Some brands, like Corsair, even offer warranties up to 14 years for good reason!
Unless you've been pushing it close to its capacity, you should be fine. I recommend picking up a wattmeter to see how much power your setup really draws. You might be surprised at how low it is, even under heavy load like gaming.
What specific model do you have? Just wondering if it's a good one."
