AX850 Ridiculous Coil Whine


gutter

Recommended Posts

I recently built a new PC with a Corsair AX850 and I can't believe how noisy this thing is. It whines constantly... especially when under load playing 3D games. It's louder than my speakers at times.

 

I knew the AX series has a reputation for coil whine, and I guess I was hoping I'd win the Corsair AX series lottery when I bought it, but this is ridiculous! I read the thread about Noisy PSUs, but none of those suggestions seemed to help.

 

Since I can't return it to Newegg for an exchange, it looks like a RMA is my only option. Have the coil whine issues been fixed yet, or is it still luck of the draw? Also, are RMAed PSUs refurbs or new units?

Yeah, when video cards aren't under load it's fairly quiet. You can still hear a buzzing sound if you put your ear next to it, but as soon as I fire up Crysis 3 - ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ! Sounds like a fricking hand buzzer.

 

I'm not sure why RAMGUY is ignoring me. Too many people returning defective power supplies I guess.

Before I proceed with a RMA I would like answers to my questions:

 

- Have the coil whine issues been fixed yet, or is it still luck of the draw?

- Are RMAed PSUs refurbs or new units?

 

I spent a lot of money on this power supply. Is asking for a formal Corsair response too much to ask?

There has been no official reports or any coil whine issues. Yes, some units have had this issue but it's a very small percentage

 

- Are RMAed PSUs refurbs or new units?

You would receive a brand new unit sealed in the box.

I hope you are right i still wait for mine, i'm very curious to see what they will sent me back in exchange for my old less than one year hx750

 

I read a lot of negative posts about the corsair products but this is normal because corsair is a worldwide company and many million people buy their products. Some of them get faulty products this is normal and they complain but the rest who play games or whatever they do and they never report that their product was solid and good. I mean those who was lucky and took a solid product have no reasons to report it anywhere.

 

The companies that fabricate computer hardware they throw away their faulty rma products?. Of course not. They can fix, clean and maybe resell for brand new. I will give a real example.

 

Before two months i paid 400$ for a brand new video card. It came with faulty fan so i rma it immediately and they sent it me back a refurbished with scratches inside in a sealed new box. Of course they apologized and i was given a brand new card but is it new ? :P

 

Good luck to all.

Yeah, I get that most of the people who post are in a minority that have problems. That said, a Google search for "Corsair coil whine" returns more than just a few results.

 

In any case, it's still disappointing to drop $200+ on a defective product, then have to pay even more to ship it back because you got a junk unit. Fortunately it sounds like people who've had to RMA multiple times only have to pay shipping once in most cases.

 

As for throwing away RMAed products, the guy who processed my RMA specifically said that Corsair scraps returned power supplies. Now I am I getting the company line and do they really do that? Who knows. I can only take them at their word. I wouldn't have bought from them in the first place if I didn't trust them.

Yup, they sell around 100,000 PSU's a MONTH! (Yes,thats the correct amount of zeros!:) )So in reality the failure rate is quite low.

Correct! So in the even that you would happen to need a second RMA ,just contact them and let them now whats wrong along with your previous RMA number and they will pick up shipping both ways.

I think what he meant is that they are not re-furbed. Except for the units they pick to do a failure analysis on in their labs. Once they are RMA'd they are sent back to the factory. But not exactly scrapped.

Got my power supply today. It seems to be a new unit. Everything was shrink-wrapped and packaged nicely.

 

So, I installed the new one, and I have mixed feelings about it.

 

One one hand, the loud coil noise while running 3D applications is much quieter. It's still there, but not nearly as bad.

 

Other other other hand, this one makes high pitched noises when I move windows around. Since that's 80% of what I do on a daily basis, I don't consider this an improvement.

 

Ideally I would like a silent power supply (other than the fan), but I'm starting to doubt that Corsair makes one. I'm going to request a second RMA. Maybe I'll win the Corsair lottery on the 3rd one.

I concur.

Thanks RamGuy.

 

The normal operating "pitch" of this one is actually giving me a headache, so the sooner you can speed things up the better. :(

 

The new RMA #: 5742888

The old advance RMA #: 1288805

 

This is what the new one sounds like when I move windows around on the desktop:

 

Sadly the pitch is at a frequency that makes me cringe.
