Product description

Size:80+ 400W

In today's power hungry world you need a PSU that can deliver and the Rosewill RD400-2-SB does. With 400W of total output power there's plenty of juice for the most demanding situations. Dual 12V rails with 27 amps of power provide plenty of independent, reliable power. As in all cases, being well connected is of major importance, and sprouting from the housing are a multitude of mesh wrapped cables to connect all your components. The mesh wrapping keeps things neat and helps to promote better airflow and cooling. Universal motherboard connectivity is ensured with the 20+4 main connector and 4/8 pin EPS connector. All these are enclosed in a flat black housing with multitudinous ventilation holes and a 120mm cooling fan. The smart temperature sensor intelligently adjusts the fan speed according to the system temperature for minimized operation noise.
