[SOLVED] PSU coil whine

[beeko]

Hey

I have loud coil whine coming from PSU which is brand new Corsair CX 550M.
When I start to play CS:GO, its very audible but when I drop my fps from 300 to 100, the sound decreases almost completely. My previous PSU was Corsair CX 450 and I tried to hotglue the components but it didn't help as the sound came from the center component which was covered with plastic.

I have tried all settings high to low but with high fps, I cant get rid of the sound.

Is there anything I can do for this?

Here are my specs...
Mobo: gigabyte ga-h77-d3h
Memory: adata 8gb + kingston 8gb 1333mhz
PSU: corsair cx 550m
GPU: nvidia geforce 1060 gaming x 6gb
SSD: samsung 760 evo + HDD seagate barracuda 2tb

Yeah. You can't use a 1080 with a double forward PSU and expect the main transformer not to make noise. CX-M is best for cheaper builds. You need a better PSU with newer switching technology (LLC resonant).

For Corsair, that's going to be CX (non-M), Vengeance (the 80 PLUS Silver one) and anything 80 PLUS Gold and up.

Alright thanks for replies, i'll think about buying one of those

 

[beeko]

Would this PSU be compatible with my GPU and wouldn't make this coil whine buzz?
Thats the same that I have now but is not modular

And how do I know if a PSU uses this newer LLC resonant technology?

Bump

The Corsair CX550 (2017) uses half bridge LLC than double forward like the (2015) CX550M. It still wouldn't be my first choice with the 1080ti.

A TX550 has a 50C temp rating and I would assume uses LLC.

Not my forte. Jon would be your person here.

Correct. CX and TX use LLC resonant. CX-M uses double forward.

Thanks for the replies

If I order a CX 550, will that be okay? Or are there better options for my machine?
Or what about this one which Dark Lord of Tech suggested (Corsair TXM 550): https://www.amazon.de/Corsair-TX550...rsair+txm+550&qid=1567835979&s=gateway&sr=8-3

My specs:

Mobo: Gigabyte ga-h77-d3h
Memory: Adata 8gb + kingston 8gb 1333mhz
PSU: Corsair cx 550m
GPU: MSI geforce 1080 gaming x 8gb
SSD: Samsung 760 evo + HDD seagate barracuda 2tb

TX-M is same as CX in that:

It's uses the same LLC resonant and DC to DC platform.

TX-M is better than CX in that:

It's Gold efficiency
All Japanese brand caps
Semi-modular
Rated to run full load up to 50°C instead of just 40°C

I ordered that TX 550 and the coil whine is still there... : (

Maybe if I order a more powerful PSU like 750 watts, that could solve the problem or am I wrong?

That's not how it works.

So what you're saying is the coil whine is coming from the graphics card?

 

[beeko]

Sorry my quick response, I just logged into a game and heard some coil whine coming out... So I think the coil whine coming from the PSU is gone entirely and my GPU is making a slight buzz which I can live with

Thanks all for help!
