Which PSU is the Most Qiet for a NAS System?

Where the choice of the PSU may even decide over the NAS system components for very low noise levels.

Thanks in advance.

there are silent seasonics, the lower wattage x series.

There are fanless power supply units available.

E.g. SeaSonic SS-520FL 520W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Active PFC Power Supply

if its just for a NAS then a lot less than 300W would be fine, so most quiet PSU's would not even have their fans ticking over at the realistic sub 100W load that a NAS would see.

my 6.5TB server pulls 65W at load.
