Seasonic x850 works great, but makes strange sounds. Is it ok?

post #1 of 6
Thread Starter 
So I recently upgraded to crossfire and I had to buy a new PSU. Before I had a seasonic 620watt and I upgraded to a Seasonic x850. It has been working fine (As far as I can tell), but it is always making this strange noise that is really high pitched. It is barely noticable and hard to describe, but it makes me think that something might be wrong with it. It has a constant squeak (very quiet) and then a chirp every two seconds (also very quiet) when at the desktop. When I start a benchmark like unigines valley the squeak and the chirps stop and the PSU is quiet, but when I hit "quit" and it goes to that screen where you have to hit escape to exit it sounds like a quiet electonic scratching sound and then when it is back onto the desktop it makes that squeak, chirp, sequence again. Is this a sign of a defective PSU? I have been doing a lot of overclocking and my 3770k is at 4.6Ghz at 1.4v (I know, crappy chip) and my two 7950's are at 1150/1600 at 1.25v. Another thing to mention is that GPU-z rarely shows the cards ever actually hitting 1.25v they are usually between 1.18v and 1.23v. They are boost cards so I don't know if that is why it is doing that. The overclocks are stable though. So what do you think? I've had the PSU for a month now. Thanks! -Josh

Yeah, I would have to agree. Doesn't sound like your standard coil whine to me.

Bummer! But ok I will do that thank you guys. I sent in the UPC for a rebate so does that mean I am going to have to go through seasonic or can I still go through newegg?

Yeah, the chirp sounds odd. I get constant steady some coil whine from time to time, but if I unplug some components, power up the system, turn it off and plug them back in again it'll usually go away - you could always give that a shot, doesn't cost anything.

I wouldn't worry about the power readings on the GPUs as long as they're stable, my understanding is that modern cards only draw as much power as they need (like the cpus) and this seems to show oddly in hardware monitoring software.

I think you will have to go through seasonic since you sent in the upc code.
