Problem with Corsair CMPSU-750AXEU.


Recommended Posts

Very sorry for my bad english, i try write a problem simplest.

I recently purchased Corsair CMPSU-750AXEU. He was in original box, cables and psu in black bag.

In first run i'm very scared a noise from psu. Constant sound "zzzzzzzz" but i know it's normal, also sharp sound at computer is turned on also at hard load system(such as linpack) this sound like short-circuiting. It is very unpleasant noise.

I want to know it is normal or not?

There may be a light Buzz or whine form the PSU but once the system is running you should not notice the noise. If you can hear that with the system closed up then I would suggest we try and replace it under warranty. Please use the link on the left and request an RMA and we can replace it.
