Power Supply Revving at random times?

Hi everyone

So I just built a brand new PC a few days ago with a couple friends of mine, and everything about it is great. Stays cool, runs Metro Last Light at max settings, tackles daily processing easily.

Up until around the 2nd day, this PC was super quiet. The only thing you can hear were the case fans on the NZXT Phantom, and that's not a complaint at all.

Here's the problem: on the night of the 2nd day, I was in Windows and the computer just started revving up. Like it was rev up for a a couple seconds, then stop, then do it again, then stop for like 10 minutes, and start doing it again. So the next day, booted it up, and still randomly revving up.

My first thought was to feel for any hotness or warmth. This revving was happening when doing absolutely nothing except sitting at the home screen, but I felt nothing but coolness. The exhausted air feels cool, and all parts of the case feel cool.

So then I took off the side panel to truly identify where this revving noise was coming from. Upon inspection, I isolated the noise to coming towards the bottom of the case, the Power Supply. So, I'm not really sure what it is; I know it's not normal because the first day of using the PC, it didn't make a sound. My room is not very hot, probably in the 70s. I also used the RealTemp program to test the temps, and the temps were at like 32, 30, 35, 40.

I emailed and contacted CoolerMaster, however, because it's Saturday, they are not open. Let me know if anyone has any thoughts, as I will probably just RMA this one, or buy a completely different one.

Specs: Cooler Master Silent M Pro 1000 W, NZXT Phantom, Asus Gefore GTX 690, 16 GB Corsair Vengeance LP 1300, ASUS P8Z77 V-Pro, Intel Core i7 3770K @ 3.5 ghz, Stock Intel CPU fan

Sounds like a faulty power supply to me. It shouldn't need to spin up that much unless it's very hot. It's possible your ambient temperatures are low but the actual power circuitry in the PSU is overheating (i.e. faulty).

The Silent Pro M line is pretty solid, but every manufactured batch has their stinkers.

Do you really need a 1000W power supply, though? Are you planning on tossing in another 690? If not, you could easily get away with a higher-quality, lower-wattage unit like the XFX Pro750W or Corsair HX650.

Well it's interesting because I was on it last night for a couple hours playing Metro, and left it on the entire night, and when I woke up this morning I am on it, and it wasn't making the revving at all.. I mean, occasionally it was doing it, but it wasn't like the past couple days where it was really noticeable.

I suppose I don't really need 1000w, however, I saved like 50$ on it with a promotion at Newegg, has a 5 year warranty, and the Silent Pro M, as you mentioned, is solid, and highly rated.

Although this is two years after this post, I would like to point out that I have the same power supply doing the same thing. It keeps randomly revving and making a sort of rattling sound when it revs down. I have cleaned the power supply and checked airflow, and everything seems to be okay. This problem popped up maybe a month after I bought it and it quickly went away, but now it has come up again. I'm posting this because I was searching Google for what was wrong, and it seems to be a faulty batch of PSUs or something.
