The SST-ST45SF v3.0 is a SFX form factor 80 plus bronze certified (82%+ electrical efficiency) power supply unit that features a single +12V rail (37.5A), 92mm “silent” intake fan and a total output of 450W (578.6W peak). Of course as expected really because of its rather low output unlike its larger cousin the SST-SX600-G (600W max/690W peak) the SST-ST45SF is not modular so all of its available power connectors are hardwired into the main unit.
Along with the main 20/24 pin power connector the SST-ST45SF also features an 8/4 pin EPS connector, 8/6 pin PCIe connector, three SATA connectors, two 4 pin Molex connectors and a 4 pin Floppy connector. The SST-ST45SF v3.0 has a reported MTBF of 100.000 hours and also features several electrical protections including OCP (over-current protection), OVP (over-voltage protection), SCP (short-circuit protection), OPP (over-power protection) and UVP (under-voltage protection).
