Hardware longevity thoughts

Built a cheap n cheerful browsing/workstation/old gaming system in January 2015. Quick spec.

AMD A8-7600 APU (Radeon gfx onboard)
8MB DDR-1600
250GB SSD
Corsair Bronze cx430m PSU
120mm AIO cooler

In 2018 I was seeing too much CPU activity and occasional lags on 1080p 60fps streams, so I added GTX 1050 (2GB, low-end, but not terrible), and it made a massive difference, as it always does.

The PSU has always been a little dodgy. Noisy fan bearing, presumably. The other night there was a bit of whiff in the air, and the noise was gone. Fan stopped? Over heating? It hasn't been repeated, but I'm cagey about stressing the PSU by doing anything video related (e.g. GPU fan spins might be too much draw), and have ordered a replacement.

Some context. Speccy gives the SSD power on time as:

Power On Time : 1942.6 days (2,830-ish real days since build)

Days into hours: 46,622.4

Into 7.5 hr working days: 6,216.3

Into working years, if five days a week (261 working days per year): 23.8 years of use, by office standards. 25.8 years, if we add four working weeks holiday. Or back to the year 1996-ish.

Not bad for a £500 system (with a £120 gpu added three years later). Here's hoping the other parts aren't ready to pop too.

I still use a 2001 (?) vintage Dell D610 laptop occasionally. Since MS dropped the print drivers for Laserjet 5 & 6, my current machines cannot print although I rarely need hard copy. Print to .pdf and then send via the C610. It originally had 5 years or so of 12+ hour days, 6 days a week so has to be up there in terms of hours in use.

A mate was using a P4 machine until he passed away around 3 years ago for producing music, I built it years ago for him and not had a hardware problem, did not cost a lot either.
My the main parts in my own machine are over 5 years old, so not too bad, one of the SSD is over 9 years old and still running fine and.

Sometimes you can be lucky and other times not
