NZXT C1200 GOLD coil whine when there isnt any load

[Merf01]

 its just been couple hours that i connected a new psu to my rig (nzxt c1200gold) and its making annoying coil whine when there isnt any load but soon as i open a game or benchmark it goes away. seen someone having same issue and said coil whine was gone after like 6 months. idk what to do rn. would my unit fix itself after some time like that guy? anyone have the same unit and has the same issue ?

(7800x3d ,4070ti super. ik the 1200w is a bit overkill)

uhhhhhhhhh any reason for the psu upgrade to 1200W?

None the less, coil whine definition tldr: When current through an inductor changes, the magnetic field around the inductor also changes. This causes a small attraction/repulsion action in the coils of the inductor, which manifests itself as a vibration/sound.

 

Could be a sign of  a poorly built psu, or poor grounding
Im not informed in the psu world so I have no clue if this is good

last one i had wasnt that good as i seen on psu tier list etc. (aerocool integrator 750w gold). thats why i changed it

The PSU is way overkill and will may even be less efficient than your previous one., why didnt you swap it for a better 750W or 850W in that case?

 

PSUs are most efficient at around 50% utilization, that would be 600W in your PSUs case, but with your GPU and CPU youre at what, like 350W on average?

yea more like 380w (just the gpu and cpu) also its not that bad efficiency wise

Plus after hardly any research I found this isn't a very high end psu...quite the opposite in fact
Only thing I see that contradicts it is psu tier lists.

But that would be under 100% load, which I doubt is happening a lot outside of Benchmarking.

My 7800X3D consumes 50-80W when gaming and my 4080 about 100-250W, so about 150-330W together

i checked it on cultists network. idk if its not a good source

Seems to use the generalized psu tier list
But again after hardly any research I see lots of complaints about this being a poor quality psu

i play mostly huntshowdown and its mostly using 260-285w on gpu and 65-75w on cpu but i get your point. i just wanted to buy a quality psu and the low wattage ones didnt seem that good.  also dont really wanna bother with returning it rn

It's a good source but anything sort of automated and generalised can have things slip through, especially when those are QA issues not consistent design issues.

I mean you kinda cornered yourself here. Using the PSU around 33% usage so you've overshoot a lot.

 

There isn't really anything you can do about coil while. You can try to return it but problem is that how much you hear the coil whine is random, like an unlottery. People who buy 4090's to play indie games run into this issue as well. Or get unlucky enough to have shit enough ears to not hear the coil whine.

 

Really just gotta live with it.

btw quick update: windows was setting my power plan to battery saver or whatever its called and when i changed it to ultimate perf. the sound is gone. there is a lil bit while the computer is starting but at least there isnt any sound while idle
