Corsair AX750 Still good?

[louno]

I built a system back in 2011 with an i5 2500k (OC 4.4ghz) using a Corsair Ax750 Power Supply. I dont think it matter much what the other components were although for GPU overtime I started with a 560gtx, then 2x 560gtx in sli, then 970 gtx (current).

I am planning a new build now, likely a ryzen 5 2600x or ryzen 7 2700x. Will probably keep the 970gtx initially and replace it with a 1170 gtx when they come out.

So my question is this... Is the Corsair AX750 still good? The warranty on the box says 7 years, so, that would mean it ends this year... This is a 80 Plus Gold PSU and you can see full specs here

But I am wondering if i should just change the PSU to be safe, or keep using this one? Also, would I be missing any connection wire or anything to be able to work with latest tech (for example nvme m2 ssd) or some other type of things...

I would like my new system to last 4-7 year and am going with ryzen because i'll be able to supposedly upgrade just the cpu in 2020 with ryzen3 or 4 or whatever... Not sure this makes any difference.

Thanks!

No problem man just use it as long as it stays with you. These are good PSU which has good protection in disaster situation. So if it pops it will not take the other PC components with it. I had a Seasonic X-850 series psu which poped once and dead. It was so intense it tripped the circuit breakers of our building. Even then not a single component of my PC was damaged. It was in warranty and they have replaced it now it is again working like pro.
Concern is if you live in a area which is prone to thunder and lightning then use a separate ups for your PC. It will protect your PSU during such power surge since the PSU warranty is going to end.

If warranty is gonna end replace it. As simple as that.

It ought to be fine. You're actually using less power than you were when you started, in all likelihood! PSUs can age a bit -- hardOCP's been doing a retrospective on re-testing old PSUs they used 10 years ago -- but you have a lot of headroom.

^ yes it's a good psu and he has headroom. But it's at the end of its warranty period. Better to replace it and have it as a back up psu.

Agreed and since it is a good quality component no need to change it unless it fails and of course if you have plenty of money lying around then buy new PSU for fun. Capacitors do age with time but still you have plenty of head room. Lastly it is not 100% sure that a new PSU will not fail.

I would love to keep this PSU, that would save me some money that I can spend elsewhere in my next build, that would be really nice, however, what happens when the PSU fails? Inevitably, I guess it will fail... likely at some point during the life time of my next build? Will it give any sign first or will it just "pop dead" and risk causing some damage to my new system? If the risk of damage to other component is very low, then i would rather keep this power supply and replace it when it fails hopefully with a bit of luck it will last another 5-7 years and i will replace it when i do my next build, but if it fails before that then i'll just replace it then, as long as the risk of damage to my other component is pretty low, i dont mind it.

Over the last 7 years, it did happen once in a while we had thunderstorms and it caused a power loss in the house which shut down the PC... it's not something that happens often, idk, once a year maybe. I dont use a UPS, but the computer is plugged in a belkin power strip which i believe has somekind of surge protection (this model)

Finally, in my original question, i was wondering about potential features or modular cords i could be missing? are the wire all the same and i dont need anything else or would I be missing anything?

Oh one last detail i forgot to mention, again not sure if it makes a difference, but, my computer is generally open 24/7 . I see on the corsair site the powersupply has a rated MTBF hours (mean time between failures) of 100,000 hours though, which translates to 11.4 years... so being at 7years of near constant 24/7 now i'm still 4+ year away from the MTBF... I should be ok? basically it comes down to what i was saying initially about risk to other component...

If the power supply has been in use 24/7 for the last 7 years I'd replace it pretty soon. If it's in a computer that's only used a few hours a day you're likely fine. I believe Corsair's warranty is based on 24/7 use. At least that's how they calculate how long they think it will last. Now that being said I'd still think about replacing it even if it's only been used intermittently just because of the warranty. But I wouldn't necessarily be in a hurry.

 

[DSzymborski]

Hmm, if constant 24/7, I'd be more inclined to replace the PSU than I would be otherwise. The protections should be fine if you don't, however.

1: No one can tell if it may gonna fail in next 1-2 years or last for 12 yrs. It may be a sudden pop and out or You may see that you tapped the power switch but the PC is not turning on. Press it few times and it starts just like normal, abrupt restart or shut down, kernel error bsod restart etc. In this case it is difficult to trouble shoot if it is psu problem or something else. Now in POP case it is extremely less likely (but not impossible) that it will kill some components. I have gone through this since my PSU is also very good quality like yours my pc was in perfect state but say there is a probability of 1% that it may kill but extremely less likely.

2: That power strip has surge protection but check out some belkin tear down videos for their quality and reliability. I would recommend you to buy a ups just for added safety.

3: Modular cords has nothing to do with non modular ones just for clatter free build and looks cool with sleeved cables. Yes you will have all necessary connections on this old psu to run your new components so don't worry.

4: 24x7 usage: If you are not in mining then it is likely that it is using hardly 120W or even less so it was running with 25-30% of its capacity. As per corsair test I am not sure but they will definitely tested it with at least 70-80% load to calculate those figures (I believe). However have to google it to know more) so don't worry you have plenty of life left.

Finally the risk! I can not assure you but simple logic is telling me that a good quality PSU that is working perfect for last so many years is trust worthy like a good old friend and with out any solid evidence you should not break this relationship
Do some more research online and as per my understanding go ahead with your current PSU.
