Question 12 year psu for a new build, dumb idea?

[Hackldackl]

I have an older Corsair ax1200i I had from an older build and I’m wondering if it’s a dumb idea to use it for a new pc I’m going to build. The pc itself is gonna have a 9950x3d and for the time being a 3060ti but I’m intending on upgrading to a 5000 series card in the next half year depending on whether Nvidia releases anything new.

the power supply itself got low to moderate use I’d say though it was driving some overclocks forsure.

Thoughts? Is even entertaining decade+ old psu a non-starter at this point?

Yes, bad idea.

What did the PSU power through it's tenure?

Yes, bad idea.

An overclocked 3930k and two 780s. But I’d go months without using that build.

Electrolytic slowly deteriorate in even the most expensive PSUs, especially if the capacitors run warm/hot coping with high ripple currents.

Electrolytics are typically rated at 1,000 to 5,000 hours at maximum temperature (+85°C or +105°C).

For each 10°C lower than maximum temperature, you can double the lifespan. So a +85°C capacitor rated at 2,000 hours should last 4,000 hours at +75°C, 8,000 hours at +65°C, 16,000 hours at +55°C and so on.

16,000 hours is 667 (24-hour) days, which is less than 2 years continuous use (24/7/365). Obviously, +105°C capacitors (as used in high quality PSUs) should last much longer.

Power electrolytics run warm to the touch due to self-heating and I wouldn't be surprised if some reach +60°C at times of stress.

If the manufacturer of your PSU gave it a 10-year warranty, it's time to buy a new one. No easy way of telling if it will last another 5 years or 5 minutes before the magic smoke appears.

Ill put it this way, do you really want to risk 1500+ dollars worth of equipment, over a 100 - 200 dollar part?
