TFX power supply for compact systems

The In Win IP-S300FF1-0 delivers 300 W in a TFX form factor suited to slim desktops and small enclosures. Dual +12 V rails provide 18 A and 300 mA alongside 5 V at 16 A and 2.5 A plus 3.3 V at 16 A. It accepts 120 V AC and 230 V AC input for worldwide use.

Fits slim chassis with standard AT mounting

Internal dimensions of 3.3 width by 2.6 height allow installation in tight layouts where full-size units cannot fit. A single 80 mm fan with smart thermal control adjusts speed to balance airflow and noise. ATX12V and EPS12V compliance ensures compatibility with modern motherboard power connectors.

Steady output up to 40 °C ambient

Rated for continuous operation from 10 °C to 40 °C, the unit maintains specified voltages under sustained load rather than only peak bursts. MTBF of 100 K hours at 25 °C per MIL-STD-217D/F indicates long-term reliability. Not for builds needing more than 300 W or additional PCIe power connectors.
