Question about Seasonic Prime Ultra Titanium

Depending on the setting (switch on the outside), it should do its job with a passive fan at low load. This works for me, the fan is usually at a standstill.
- Even in this segment, minimal coil whining cannot be ruled out, depending on the load. However, this should not be too strong.
- The fan clattering, however, should not be.
Since I also operate a fanless system, I can understand you well. Due to the "premium" claim of the power supply (and price), I would try an exchange.

I'm sorry to hear that! For me, the part is inaudible even under load.
