High pitched sound with two HX650..

Recommended Posts



Recently i purchased a brand new HX650. Few days later, i went back to the shop because the PSU made a high pitched sound.


The seller gave me a second brand new one; i installed it, and the same noise came again.. and worst than the previous one...


I must confess that i am a little bit frustrated and this sound gives me headache, it's really really screech, i can easily hear it through my music and appartment..


So now, what options do i have? I don't want a HX650 anymore. Is there a way to change this PSU with a HX750 (CWT) ?


I tried another PSU (seasonic) and it works flawlessly in my computer, no parasite noise.



I request a RMA please, and if i must pay the difference for a HX750, i will pay. Just tell me the process.



Thanks per advance.

That normally would be an issue with the Video Card or system configuration, can you test the PSU in another system? And if you want a different model of PSU I am sorry but you would need to go back to your reseller, we would only be able to replace for the same model that you send in.

Thanks for the reply sir. Seriously too much problems for my first experience with Corsair... i give up. I got a P6T with i7 940 as second setup, but you will understand that i don't want to kill my mobo or something else with this psu..


I don't want to be rude but around me a lot of people with HX650/750/850 experiment noise issues with their psu.. A great deception for me. Anyway.
