I'm building my own PC and I'm considering reusing the power supply from a prebuilt system I bought back in 2020. Here are some of the parts I've gathered for my new build: a Ryzen 7 9800X3D CPU, Gigabyte B850 Eagle WiFi 7 Ice motherboard, a Thermalright Phantom Spirit 120 Snow Digital cooler, a Musetex Y6 case, and 2x16GB Corsair Vengeance RAM at 6000MHz. I'm also planning to keep my RTX 3070 from the old setup, which was paired with an i5-10400F on an MSI H410M Pro motherboard. The new PC should draw about 478W under normal conditions according to PCPartPicker, and my current PSU is a 750W unit, though I need to confirm its model because I'm not fully sure of it. My concern is that I haven't cleaned the old PC in a long time, and I don't want to risk damage to my new components from a potentially low-quality or dusty PSU. I will check the PSU model soon, but in the meantime, I would really appreciate any advice on safely cleaning the PSU or knowing what signs indicate it needs to be replaced.

I’d recommend against reusing the PSU from a prebuilt if you can help it. Those units are often the lowest quality without good efficiency ratings or circuit protection. I understand the temptation to save money, but it might not be worth the risk for your new components. For a little extra, you could get a reliable PSU, especially since there are good deals out there right now.
Generally, a power supply that's about five years old can still be okay, but it largely depends on the brand and quality. If you can blow some air through it to clear out the dust, that could help a lot. Also, if it’s from a reputable brand, it might still be under warranty, which is worth checking into.
If you're worried about the dust inside your PSU, it's better not to open it up, as that's risky. Just do your best to clean what you can externally. As long as the PSU is decent quality, it should work fine for your setup.
