Question New build with old PSU

[seagatedoge]

I am planning a new build, roughly: lower-end X570 motherboard, Ryzen 3800X, Nvidia 1080. I was planning on using my existing PSU for it: a Seasonic XP-1000 Platinum 1000W that I have been using almost daily since July 2013.

There is conflicting information in my research so far on whether this is a good idea. Some posts warn of the PSU failing and destroying new parts while other posts say the effect of age on the PSU is low and if it is a quality unit it will fail without destruction. I used to have an 850W Gold CoolerMaster that lasted a month before it blew up so I'm not entirely convinced by the age argument. Also, my components were not damaged even though the house's fuse box shut off.

Any advice would be appreciated

The thing with PSU modules is that the manufacor of some cheaper models may have being cheap on it's electrolyte capacitors (electrolytes for short), and cheap electrolytes have the tendency of short live, life span depends on the load.

If a PSU is in a state prior to failing, there is a tendency that other hardware start being unstable. The chance for this unstability occurs depends on the mainboard and GPU's own capability to smoot the voltage from PSU (use of electrolytes and internal voltage regulators).

Therefore - some cheap motherboard will behave unstable until PSU is replaces, wile other may live just until PSU fails completely.

And there is also other factors, like the internal working of the PSU - so that some PSU models, even if they have failing electrolytes may actually behave functional for some time before they get into a completely shutdown.

Unfortunately there are models in the marked that - in case of failing - it outputs voltage variations that cause havoc to other components such as mobo, cpu, gpu etc..

That sait - if you don't experience any ustability of your current setup I beleive that keeping the current PSU is the most cost efficient choice.
But - without the full documentation of the GPU, it is not possible to tell if it have some inbuilt protection against dangerous voltages variations when failing.
