Question Buy a new PSU or use my old one?

[vffountain]

This Christmas I'm going to be upgrading my current 7yr old desktop, which currently has a 600w Corsair PSU. My potential upgrades will be:

AMD Ryzen 7 3700X (from AMD FX 8320)
NVIDIA 3070 RTX (from EVGA 970 FTW)
ASUS TUF X570 Motherboard (from ASUS M5A99FX Pro 2.0)
32gb DDR4 Ram (from 16gb DDR3)

With that, should I also upgrade my PSU as it's only 600w? It's been running perfectly since I bought it, but I have no idea what the life span of a PSU is, or if it's a good idea to push an old one further with newer hardware.

As a side note, I also have an old Dell H750e-01 I took from an old XPS desktop my Grandpa had before he passed away. It's from 2010, but the PC was only used for a couple years after he bought it. Is that power supply worth using? Or too old to even consider?

Replace it. And if it's a Corsair CX, it wasn't a particularly good one in the first place.

And the second one is a hard no. It's probably a worse idea than the old Corsair.

Get a new, quality PSU. A safe, dependable power supply is the most important part of a PC, not an afterthought after the fun stuff!
