Corsair ax750 vs ax760. which one is less likely to have coil whine ?

post #1 of 7
Thread Starter 
Hi!
So after reading some reviews I noticed that there is a lot of complains about this two psu suffering from coil whine. Before I buy one of them I want to know is there anyone who have a working (ax750 or ax760) that doesn't suffer from this coil whine.
Thanks in advance.

Update: please don't suggest any other power supply, since those are the only one available at my local store, thank you.

The Cooler Master V700/850 is the same PSU as the AX760

And the V has far less coil whine

AX750 is Seasonic KM2

AX760/V is Seasonic KM3

There are better power supplies for the same price or lower (EVGA's new stuff, Coolermaster), but if you have to get a corsair model, I'd go with the AX750. I've had nothing but trouble (coil whine) on three new AX860s.

After the third one developed coil whine, I looked elsewhere.

Some of the FSP Aurum´s can trade blows with the AX750 and they are often very cheap if you live in Asia or Australia

Was the coil whine audible from where you sit, or you can only hear it when you go close and try to listen to it ?

Why do you want to pay more money to get something that is worse?

I could definitely hear it from where I sit. My PC is on my desk, but not right beside my head, and it was a very audible high-speed chirping noise. At first I tried to ignore it, but it was the kind of noise that is hugely irritating because it doesn't fade into "white noise."
