Hey everyone! I'm on a tight budget and recently scored some great deals on new parts for my PC build. Here's what I got: an i5-14600k, a Gigabyte B760M DDR4 motherboard, 32GB of 3200MHz RAM, a 1TB TeamGroup NVMe SSD, and an Intel Arc B580 GPU. It all came to about $530.
The catch is, I want to reuse my old Thermaltake 630W semi-modular PSU from my previous build (which was an i7 first gen and GTX 970 setup). It's about 8-9 years old but has been working fine. However, I'm a bit paranoid about using it with my newer components because I've heard that older PSUs can potentially fry them. What do you all think? Should I risk it or just buy a new PSU?

I found a 1000W PSU from Seasonic that was 15 years old, and I trust it way more than a new, cheaper model. It's all about quality, not just age! If your PSU has protections, it should be safe, but double-check the model—if it’s the Smart SE 630W, it's a solid choice. Just monitor things closely.
Unless you’ve been pushing it to its limit, I think your PSU should be fine. A wattmeter is a great investment to see how much your PC pulls during heavy use. For example, I often stay under 500W, even when gaming on high settings.
Any PSU can fry components if there’s an issue, but you're right to ask if you can afford a new one. An 87% efficiency rating is good. If your old PSU is still working and not under strain, you could use it temporarily, but plan on upgrading soon. Look for brands with warranties of 10-15 years—that’s a good sign.
It's pretty rare for an old PSU to fry new components. If it's still under warranty, I'd say go for it! But if not, think about getting a new one—you definitely don’t want to cheap out on this. Some brands, like Corsair, offer long warranties for a good reason: a good old PSU is often better than a cheap new one.
Honestly, just grab a new PSU. They're not that pricey, and peace of mind is worth it!
I used the same PSU for 13 years across three builds, and it just kept going until I finally upgraded because my new GPU wasn’t compatible. Sometimes the older units can surprise you if they were well-made!
Should I only look at gold-rated PSUs?
