By using a redesigned PCB combined with smaller MOSFET and heat sink components, the internal space within the power supply was increased to enhance heat dissipation and airflow to result in better component cooling. The eightfold increase in heat dissipation keeps the internals of the power supply cooler, eventually leading to improved product quality, long-term reliability, and more efficient operation. The redesigned layout of the power supply components and its improved thermal performance creates versatility and allows the power supply to be safely installed in any orientation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHybrid Silent Fan Control – Fanless up to about 30 % load\u003c\/strong\u003e\u003cbr\u003eThe industry's first, Seasonic patented, advanced three-phased thermal control achieves optimal balance between silence and cooling.
