Question Noise from Thermaltake PSU ?

[Onsali]

Hi,
This weird sound started coming from my PC and apparently from the PSU, I reckoned it was the PSU fan
I took it out and attempted to jump it but the noise only comes when its given power, the fan continues spinning after I cut the power but the noise is totally gone.

GPU: 2070 Super
PSU: Thermaltake Smart RGB 700W

Please check this attached video for detail, I hope someone can help me out regarding this.

Your current PSU has not the right topology for a system like that. Get rid of that crappy Thermaltake PSU and buy a unit with LLC + DC-DC like Corsair TXM Gold, Corsair CX-F, Corsair RMx, MSI MPG A-GF, Enermax Revolution D.F. or XPG Core Reactor.

Ah [swear-word removed}, I did not know; one would assume pc part picker would have alerted me about compatibility issues. I called the store I bought it from and they are asking me to send it for RMA.

So the noise ceases right away when you shutdown the PSU despite the fan still spinning ? Sounds like a terrible case of coil whine, some coil whine is expected from this PSU, it's low-end and doesn't have zero-voltage switching but this is exceptionally loud. In any case, it's not a good PSU, replace it if possible, i would even think that the coil whine this loud is a ground for RMA.

Of course they want you to rma it, they don't want to deal with it. If you bought in the last 30 days, take it back and get a decent psu and like @--SID-- stated, stay away from TT. There are much better options, never cheap out on the psu, its the heart of your system.
