Would a psu damage other components if it's about to fill its lifespan?

Let's say you're using a 6 year old psu and upgrading your gpu,(with same watt required one)
and you don't wanna switch your psu since it still doesnt have any problems.
Would my psu just turn off and die in peace without harming anything else when the time comes considering it served me well so far and didnt have any problems?

It depends on what "dies". If a capacitor dies, that can affect the voltages when there is a transient load (a sudden change in load), and if a PSU has working protections, it'll detect a voltage that is too high or low and shut itself off. If something like a transistor breaks, it may just be completely incapable of working altogether. Worst case scenario is a bunch of capacitors start leaking and that creates horrible ripple (fluctuation of voltage) which can damage hardware. But like I said, the capacitors can also affect the voltage level, so it all roots down to if your power supply has working protections or not, and how good those protections are.

What is your 6 year old PSU?

it's a really unknown brand, not even close to stuff like xfx,seasonic etc.
it has voltage protection tho,as long as there is that, would it have any problem when it finally stops working cuz of the ended lifespan?

I love the psu because it legit worked without any problems for all this long , didnt even hear fan voice once although %99 of people would say i never heard the brand and it s a tier 4 psu.

Just because it says it does, though, doesn't mean too much. Many units set the thresholds so high or low that damage is already done before the protections decide to kick in. Other protections may be built better to check the voltage more frequently (for example, maybe 100 times per second opposed to 50). Over voltage protection is a standard requirement all PSUs must have.

If this new machine is anywhere over $400 I'd probably use a new PSU. If your current PSU was running a 100W rig, I'm not surprised it lasted 6 years. But if you're building a high-end gaming rig, get a new one.

what if my new rig actually has even less power consumption than the old one? (i'll switch from an amd fx to skylake)

here is what the psu looks like.
i was using an hd 6850 and fx 6300,now will be gtx 950 and a skylake 6600

It'll work on your new components, seeing as your old ones were more power-hungry. I'd still like yo know your PSU model though, I'm very curious.

I posted the link of the psu's pic above o.o
it's something called aopen z550-12ae3 which i had with the case i bought.

Also,thank you for your time ^^

Eh, if I were you, I would just get a new one. You got a good 6 years out of it, I wouldn't push it much further.

Just because a PSU is not dead also does not mean it's causing negative effects on hardware. If a PSU has poor voltage regulation, or ripple and noise suppression, it can decrease the lifespan of your hardware, for instance.

But it's up to you, if it's been working fine for 6 years, feel free to keep using it. I won't stop you.
