PSU Coilwhine After GPU Upgrade !

[Gundars]

Hello , i'm writing today about an issue i encountered !
I got a new GPU recently RX7900xt to replace my old 1070ti ( it served well , but got old).
Then i started having coilwhine all of a sudden coming from my PSU - EVGA Supernova G+ 1000W Gold rated (its deffo the PSU whining , i really got my ear in there ). Also the PSU only whines under load , like in-game also in Furmark Bench .
While i realise Coilwhine on itself isn't a lot to worry about , as its just a negative byproduct of a normal electrical operation !
And i realise this could also just be caused by the vibrations of the increased power draw from the new GPU !
I've had this PSU since 2019. and it was ok all this time with no coil whine , at least with the power needs of 1070ti !
Could this newly appeared coilwhine mean an undrelying issue that has arrisen with the higher powerdraw from the newly aquired rx7900xt ? Or maybe is sort of was allways there and i didn't realise it because i wasn't drawing that much power with the old card ( 1070Ti ).  Am i just worryed for nothing ? 
Other than that , all seems to work fine (Temps ok , not crashing or anything) Just that sudden apperance of PSU coilwhine with the new GPU upgrade got me a bit on edge !
Before i got the new card i figured my existing EVGA Supernova G+1000W Gold rated Psu should be able to pull the load ! I can live with the noise if i can be sure the PSU won't suddenly destroy my system or doesn't under-power it and corrupt data on any components !

Anyone with some advice out there ?

Try using separate cables for the 8-pin power, balance your 12V cables differently.

Do you mean separate 8 pin cables from PSU To GPU ? I allready use 3 separate cables for every GPU power connector !  Would it change if i plug the cable in a different 8 pin VGA slot on the PSU ? In any case , is the whine a reason to be concerned ?

Yes. You can try switching them, even using fewer cables.

Coil whine is not dangerous, but it's annoying.

Im more worryed than annoyed if its just the noise i can live with it for a while ! If its not telling me its dying ! So you're saying there is no imminent threat and it would last me 2-3 months more without destroying my system , till i can get a decent replacement ? I'd hate for it to die right when i got the new card in !

Coil whine is pretty much expected when pairing a modern high end GPU with such a low end PSU. The 1070 Ti is pretty low power, so it wouldn't cause the PSU to have coil whine the same way a 7900 XT would. If the PSU is not shutting down under load, you can just keep using it. If the PSU shuts down or if the coil whine bothers you too much, you can replace it.

Well ,nothing has crashed so far ! I had the PSU before the GPU and figured a 1000W should be ok, honestly i thought my psu is not that crappy ! Well i will deffo consider a better replacement ! Are there any suggestions  what should i consider ? A 1000W 1200W platinum rated ? Would that be better ? Or are there are other PSU parameters i need to consider ? Like Single Rail or what not ?

The 7900 XT draws a bit over 300W, so a good 750W PSU should already be plenty. You'll want enough wattage to handle your parts, but going far above that will usually mean compromising on how good the PSUs. The 80+ rating is just for efficiency, and says nothing about how good the PSU is. Single rail is just the marketing way of saying that the PSU cut corners on the protections by omitting multi rail OCP.

 

Typically, I'd look for a PSU with a half bridge + LLC + DC-DC topology; that performs well (regulation, ripple, transient response, hold-up time); that has good, working protections; is quiet (and with good fan control); and is nice to work with (e.g. no in cable capacitors, HCS terminals, easy to find custom cables, whatever you want). No PSU is going to be perfect, so it's just about finding the compromise you're happiest with, for a decent price. Good reviews, such as those by Aris on HWBusters, THW and TPU are useful resources. The full reports on Cybenetics are also a good way of finding a decent amount of info on PSUs.

 

If you want specific recommendations for PSUs, where are you buying from? The pricing and availability of PSUs will vary, and so will any meaningful recommendations.

Would any these be ok , or something of the sort ? They're supposed to be newer gen ATX 3.0 , i was thinking about more upgrades in the future so i need something that migh handle them , so i need more than 750w . And hoping none of them would have Coil whine !

The NZXT. Cheapest and best overall performance .

I researched this particular model sems like a good buy , but some people say this NZXT can have coil whine ! Even found a vid with this thing buzing  .And thats what im trying to avoid ! It just Cannot have coil whine ! I already have coil whine !

Also ! The NZXT C1200 just has too little connections it just has 4x8 pin slots ! With an AMD card this is a no go because AMD still don't use the new 12VHPWR , this is more viable for nvidia and ! And you have to daisy chain AMD cards with this thing on AM5 , i prefer 3 separate cables ! On top of that if someone upgrading to AM5 with an AMD card ! This PSU will not have enough slots to optimaly accomodate all components without daisy chaining ! AM5 requires 2 CPU cables ! So quite a poor option, for the future !

Any PSU can have coil wine. It depends on the combination of PSU, GPU and grid.

The NZXT has decent cables. 2 cables can technically carry 720w. The PCI-e connectors are rated for 468w each. One single cable and one daisy chained is no problem at all.

Well you mentioned this to me also at Tom's hw , and i'm sure you know more about those things than me , I'll take look at that model again , if it can stably carry power for my current setup (and future because i plan to convert to AM5 at some point ) with the daisy chains i guess its ok' ish , but they just look a bit ugly  . And also that coilwhine , i really don't want that ! BUT I guess if you search coil whine for a perticular model in google , you will only see whiny PSUs despite brand or model based on search citeria ! I guess thats why they call it the Sillicon lotterry !
