CX 750m Power Supply Issue

[jetpacksam]

Hi,
New guy here.
Just after completing my 1st build/transplant, the PSU throw out a high pitched whine, loud coil whine I'm guessing. It happens under stress, though not always and always happens when waking a 3tb internal out of sleep for defrag. At least that's what I think is going on.
Ran through HWMon and everything seems well below what the specs indicate they should be.
Would some one please take a look and see if you can spot anything?

I strongly suspect I will have to replace it.

Current Build:

PSU: Corsair CX Series, CX750M

USE HWINFO to check your build , HWMonitor is useless , if those were your PSU voltages for real it wouldn't run.

Install then look under sensors tab.

Thank you for the timely response. Done.

Thank you for the help.

Nothing looks out of line , and now you can notice with HWINFO the PSU voltages are reading correct and perfectly in spec.

The CX750M isn't the greatest quality wise and some do develop Coil Whine , won't hurt in most cases , just annoying to hear.

Would you have a guess as to what is causing that noise issue? as I mentioned, it sounds like coil whine but it sounds more...industrial if that makes any sense.

 

[Dark Lord of Tech]

Are you positive it's the PSU?

Is it high pitched whine or rattling?

 

[jetpacksam]

It definitely is not a rattle. When the drive comes out of sleep, it sounds very like a noisy cd drive revving during a read. And it only occurs when there is a spike in a power draw, at least thats when ive noticed it, which led me to think that it was the psu.

 

[Dark Lord of Tech]

Probably is Coil Whine , no real fix for it , will come and go , usually more prevalent when stressed.

CX series isn't the greatest quality wise but there is a lot worse out there.

ok, thanks for the re-asasurance
