Here are a few photos of the Seasonic X-Series XM2-1250 power supply showing the components and internal layout.
The XM2-1250 incorporates a reliable half-bridge topology with LLC resonant controller on the primary with two DC-to-DC converters (+3.3V and +5V) on the secondary located on the modular X-Series connector board. All of the capacitors are high-quality components with predominately electrolytics on the main PCB and solid polymer caps on the X-Connect board. The three primary caps are made by Nippon Chemi-Con and rated for 390 uF, 420V, and 105°C.
