PSU is now 4 years old should i upgrade?

[Kumoko]

i have a tier B psu probably not the best out there but its serving me well and warranty is only 5 years should i keep it then until that warranty is over?

If it's working fine then there's really no need to replace it unless it doesn't have enough wattage to handle power spikes with the new GPUs.

should be fine

if its any good it will make it 10+ years

If it works and is powerful enough there is no reason to upgrade.

I had a PSU for over 7 years that was just bronze. As long as it doesn't crash your system or do a full shutdown, keep using it. It doesn't improve on FPS at all and those PSU cost quite a bit. Switched to a 850W gold just for my 3080 since I was getting full shutdown on my previous power supply in very few games.

a good psu will shut off when it goes out of spec, forcing you to toggle its power switch
poor ones will keep trying to power the system, reboots or hit soft power to turn it on again and fail again at a high enough load

Bronze, gold, Platinum and the other types only refer to the PSU efficiency. You could have a titanium PSU that is low tier, short warranty and fails during or shortly after warranty expires. Then again you could have a bronze that is high tier, long warranty that survives years after warrant expires. I've had a PSU last a decade and that wasn't even bronze.

Point is those ratings don't reference anything other than how efficient they are at supplying power to PC without losing some in the process.

I've had plenty of Corsair PSUs that are used every day outlive the manufactures warranty.
No need to replace it if its working fine.

My P.S.U dates way back to year 2006 it powers up my p.c 12 hours a day every day for the last
11 years i have had it from E.Bay.

Im using a Thermaltake from like 7 or so years ago if not more and still working fine (surprisingly)
Just dust it out now n then and you should be good

It's not required to change it if it supports your pc properly(correct wattage) if there are no issues, just keep using it. Im using mine for like 4 years now and got Corsair HX1000i works fine since the assembly

Nope. No reason to preemptively replace a PSU if it's not resulting in issues, but be aware with aged stuff, strange issues can result that might be sporadic and rare (like with capacitors in a PSU or motherboard being aged) which might be from the old part. If yours is a good unit and 4 years old, this shouldn't be a concern though.

Nephew is using my old PC Power & Cooling Silencer 610 PSU I bought back in like late 2007 or so, so it's over 13 years old now (hardware it's powering is a Sandy Bridge-based platform with a meager GTX 650). I used it myself until ~2014 when a change in case necessitated a change in my PSU. The main issue was the ATX12V CPU cable no longer reached where it needed to go (unless I ran the cable over the front of the board), as the new case situated the PSU at the bottom, and the PSU comes from the day and age that PSUs had the fan at the rear and were meant for the top of the case, but funny it has no issue reaching in his case (same brand but different model, and similar size). But the functionality of it was never an issue, and it's a solid (though very aged) unit from its time, so unless you see a risk of it taking out other parts, no reason to preemptively replace yours.

there is no harm in buying quality psu ahead of time, then if/when one fails you can swap it out without having to wait

IF the PSU has just enough, or a smidgen above what is needed, for present system, then yes, conceivably, with passing of time and aging components, it could be a factor. But if the PSU has more than sufficient, then it would age well.

I'd built a system with a SilverStone OP1000 some15 years back, it took the various upgrades and dual GPU upgrades along the way. I'd releagted it to a running a simple i7 2600K+AIO/16GB RAM/GTX670 which I'd then sold to my friend for cheap....real cheap. Anyway, that PSU is alive and still kicking in his rig. How that for longevity?

When it comes to PSU, I'd pay till it hurts for a powerful one, sometime way OP, and I'd pay as much as I could afford for a good tiered Corsair/SilverStone, Enermax, Seasonic,etc. Presently, I have 3 + 1 (spare) PSUs rated at 1kW or higher.
