Change RM750x for RM/HX1000 issues


Recommended Posts

Hello Everyone,

 

I hope you will be able to give some advice about my case I'm struggling with.

 

So Currently I have a PC with the following components:

Intel Core I9 10900k

Asus Prime Z490-A Motherboard

Gigabyte RTX 3090 Vision

Samsung EVO 970 Pro

NZXT Kraken x63 Cooling system

Corsair Vengeance Pro 32GB 3600mhz

 

Initially I had RTX 3080 GPU with Corsair RM750x PSU, which working perfectly, even with RTX 3090 replaced on board.

 

I've thought that the RTX 3090 my need a bigger power supply and will be safer if I go with Corsair RM1000x. Short afer I had to refunded it to the shop because of buzzing coils whines appearing.

Then I've decided to go with platinium HX series and I bought HX1000, which has buzzing coils whines as well.

After that I've contacted with Corsair to approach warranty RMA proces and Corsair sent me replaced HX1000 which I tested yesterday and it has buzzing coils too.

 

So to sumarize:

 

My initial RM750x - working perfectly on every GPU configuration.

RM1000x - had buzzing coil whines and refunded in the shop

First HX1000 bought(established as defective by Corsair Support) - had buzzing coil whines and get RMA procedure to replace for healthy unit

Second HX1000 - which I got from Corsair as replaced unit, has a buzzing coils as well.

 

So I had 4 Corsair PSUs units and just only one RM750x is working as intended. Every 1000w PSU has buzzed coil whines, which is kinda surprising to me.

 

I've thought that, it maybe something wrong with my system and I've tried several solutions like:

Cables changing, plug directly to the wall, changing bios settings - nothing helps, especially when we taking into account that 750x working fine without any doubts and trick solutions.

 

Any thoughts? Any advices or suggestion will be much appreciated.

 

Thanks,

Krzysztof

Most likely going to be due to dirty electricity being provided to the computer. Try the system in a different room that is on a completely different breaker. Could also need to utilize a UPS depending on the age of the electrical in your residence in order to clean the power source up.
