Question New PSU is very loud

[QuestCZ]

Hi there, I've just finished building a new PC and I've run into problems with the Seasonic Focus GX-850 ATX 3 (2024) PSU. Immediately after pressing the power button the PSU fan gets very loud, it's by far the noisiest thing in the PC. And that's just when being in the BIOS. Even thought the used components (9800X3D, 7900XTX) have high idle power consumption, I don't think this is OK. When I press the "Hybrid mode" button, the fan stops and the PC is pretty silent. But in order to use it, I shuld place my PSU that the fan faces the motherboard which I don't really like to do. And besides that, I guess it would get loud again in high load. Seasonic claims this PSU to produce 20dB under full load, and this is definitely more. Should I try to claim warranty, or am I doing something wrong?

psu fan should be facing the bottom of the case. thats what the vent is for.

and are you certain its the psu fan and that nothing is hitting the fan blades.

Yes, it does face the bottom of the case. I'm sure there is nothing hitting the blades, it doesn't sound like something is physically in the fan, just like high RPMs.
