Dell PSUs are the worst. My wife's XPS 13 PSU went bad after just 4 years of use...

4 years isn't a bad lifetime for a laptop PSU. I know I kill the cables on mine way before the 4 year mark.

One of the underrated facts of USB-PD; replaceable cables. No need to replace the brick if the insulation frays.

The PSU itself is supposed to last way longer though... Never had a laptop PSU die on me until the laptop actually dies first for unrelated reasons.

I don't get what people are doing to break PSUs or cables. I've never fried a laptop PSU nor destroyed a cable in, whatever, 2 decades of laptops?

I am willing to accept that cables can get damaged, but I don't think a PSU outright failing is something we should accept as "normal". Unlike cables, their longevity shouldn't be related to physical handling.

Did the cable break? I had two PSUs with a broken cable after extensive usage.
