H1U 1U Power Supply
This Seasonic industrial power supply is 80 PLUS® efficiency rated and it features a high reliability ball bearing fan. Fully modular cables and easy-swap connectors add a new dimension to its versatility, while the Seasonic Smart and Silent Fan Control (S2FC) system make it a silent performer. These units comply with the latest PFC harmonics (IEC1000-3-2 and EN61000-3-2 standards) and are protected against short circuit, over voltage and over power. On the 3.3 V rail there is no minimum load requirement for this unit to work properly.
