Over the years Seasonic have been behind some of the highest grade fanless power supplies on the market. The X-Series 460W and Platinum Fanless 520W bring back some great memories for me. It would be fair to say that Seasonic have taken their time in releasing a modern day successor. Enter their new Prime Titanium Fanless supply ? offered in a staggering 600 watt capacity. Is this one of the finest power supplies of 2017? I would go as far to say that it is quite possibly one of the finest power supplies ever made.
