Corsair AX850 stopped working almost 4 years since new.

I received my CyberPower PC with Corsair AX850 Gold PSU in Jan of 2011. By Nov of 2014 the PSU stopped working.

So the PSU has lasted almost 4 years. Is this normal for Corsair's highest end PSU line?

Does anyone know of the AX series has a lifetime warranty? I didn't get packaging or box for the PSU as it was assembled by CyberPower PC.

Thanks
 
I don't think any PSU has "lifetime" warranty, sorry. And since your bought it in a system from an OEM, therefore you are not the first owner, so I bought that you have any retail warranty, even if it were still covered.

I think that you'll just have to suck it up and buy a new PSU. 🙂

Yeah I am all set to buy a new PSU but read somewhere of lifetime warranty provided by some hardware manufacturers so thought I might ask here even thought I was pretty sure it was a long shot.

Is 4 years a typical lifespan for High end PSUs?

No, I think that the retail warranty on that PSU is five years. I would assume that most would last longer than that. But it depends on many factors, such as load, temps, dust, and electrical power grid disturbances or nearby storms.

If you really want a PSU to last, you should get a UPS (battery backup). At least that's my theory. That way, the battery backup absorbs the surges and not the PSU, and it also kicks in in the event of a brownout.
 
No manufacturing process is 100% perfect, especially when we're talking about units lasting years into the future. I would speculate that failure rates are targeted to be in the mid-to-upper 90s. Unit death due to grid issues and "shocks" like lightning, well, cannot be controlled. With PSUs, a lot of soldering is involved, and it is quite amazing that so few units get bad solder joints with the many points that need to be soldered. The silicon chips are manufactured in an amazing way on the microscopic way, but things can go wrong at that level.

With reliability, a lot of it is about the "pathway" staying "open", with the proper amount of "throughput", and in a consistent manner. The high-end is not solely about reliability, but having as little energy as possible wasted as heat and making sure that the DC current is very well-filtered and within specs.

Not every UPS does that. I believe your basic $40 UPS is one that has the computer fed by AC power UNLESS the power cuts off, then battery kicks in. Those are so-called offline or standby UPS. The line-interactive ones might offer some voltage regulation and other "conditioning". "Online" UPS provides the best "buffer".

possibly not even a new unit in the first place. contact corsair with the serial number and hear them out.

It was the PSU I speced for my PC from cyberpower PC. I placed the order for the computer in Dec 2010 and received the unit in Jan 2011. I just assume these computer builders all used brand new components as that is how they are advertised.
 
I'm sure you were sold something new. I think what he means is you might not need to go get a new one. Give Corsair a call. They have some of the best customer service in the industry.
 
Hi guys, a little update.

I just talked to Corsair customer service as you all suggested. He said to get a RMA and send the original invoice from CyberPower PC and they would send out a new unit. They said the warranty was 7 years on my PSU. So I am well within the warranty period.

Thanks for the tip all.
 
... i'm afraid i actually meant that; it's just that i'm surprised that a tank like the AX850 would blow up in 4 years, so i figured cyberpower cheated and put a refurb in place of a new unit. (maybe the kid building the pc swapped his for the new unit?)
 
First the fan stopped working. So I removed the fan and placed a similar sized fan underneath the unit to provide airflow. About 1.5 months later the unit stopped working altogether.

No comment on Cyberpower PC but the $200+ in mail in rebates that I was eligible for was never reimbursed to me , even though I followed all the steps stipulated for the MIR . The MIR was from various manufactures but none materialized.

I wouldn't say CyberPower is the best name out there, but it is a pretty big name in it's field, so I wouldn't expect them to set you up with a refurb unit.

I am glad, and not too surprised, to hear that Corsair is taking care of you. The one-year warranty is for CP's service and parts, but does not necessarily limit the warranty of the parts themselves. The big-name OEMs usually sell computers with cheap parts with warranties that don't go beyond a year, so it doesn't matter. But when you pay a little extra for something like a CyberPower with quality components, one does benefit from the better parts they include.

Hope all goes well.
