Our in-depth analysis of the 750 W model of the X-Series power supply from Seasonic, with a fully modular cabling system and the 80 Plus Gold certification.

The Seasonic X-Series brings the 80 Plus Gold certification and a full modular cabling system. It was the first power supply series where the DC-DC converter was installed on the same printed circuit board as the modular cabling system. We've already reviewed the 560 W, 650 W, and 850 W models, and they all got great results. Let's see if the X-Series 750 W is also a winner.
