Hi guys so I have this issue with my new build (2 weeks old pc) and it's driving me crazy.

For the last 5 days or so (not always, sometimes it stops doing it for 1 hour) occasionally my pc makes a short "grrr" every few seconds and repeat for a good 1 minute or so. I thought it was a fan cable in the way of a fan, so today I opened it up and to my surprise I pinpointed the sound coming from my also brand new Corsair RM750X PSU.

I have a video of this, but in order to hear it you will probably need to use your headphones and pump up the volume. You can safely do it, there are no loud sounds in the video! (you can hear the sounds at 0:07, 0:15, 0:23, 0:31 and 0:41).

What should I do? Should I send it back?

Thanks guys, I'm getting paranoid and afraid this can destroy pc or something.

If you tamper with anything, you void the warranty. The fan is inside the shell, to access it you'd need to break the seal, voiding the warranty and any hope of rma. It's ill advised.

Send it back, many people have issues with corsair psus. They ask top dollar pricing but rarely deliver on quality. I was looking at a top of the line ax1200 for awhile but decided against it bc of so many bad reviews (from customers). You'd think If you spend 300 on a psu it would be legit. Today's day an age anything you buy is a cheap shoot.....hence my note 7 smh

I think your psu is just angry. The guy under you is right. Many people are not informed about the short comings of corsair's PSU line up. Thermaltake, Antec, and EVGA PSU's are really the only ones that I trust.

It's angry? I certainly hope it doesn't exact revenge on the rest of my components!
But should I send it back? I always used corsair psu's since forever, never had any problem with them...

Yeah like I said the first reply is right. The worst that can happen is they will say the PSU is fine and that will allow you to move on to another conclusion, but if they replace it and you no longer have the problem, then why not? RMA's are not usually that bad. If you don't have a back up PC I can understand the struggle. I keep my old desktop and a laptop on stand by in case I ever need to switch something out. Good luck!

I guess there's a first for everything. In the past 3 years I've had a micro sd card corrupt, under warranty free replacement, a ssd corrupt, under warranty free replacement, bought a defective hrs 980ti, returned and replaced. When it comes to psus you really have to do your research. You just may have been lucky until now. Keep it or don't but you're gambling with the rest of your pc.

Pc's are wierd. The chances of a lemon are quite small, even with questionable practices. I've been tinkering around with pc's for @30 odd years and had only 2 things ever fail, a CoolerMaster psu after 4 years of use and a Seagate hdd that was donated after an upgrade. And I'm the guy who cleans and builds pc's usually sitting in the middle of the carpet using a vacuum cleaner and small paintbrush.

The new RMx are actually quality units, some of the better made of Corsair's questionable units, and although I personally am not a fan of Corsair at all, I'd have no issues recommending that unit. You got a bad one, it happens occasionally.
