SFX 300 W power supply for compact builds

This SilverStone SFX unit delivers 300 W of continuous power in a 100 mm long chassis. It carries 80 PLUS Bronze certification with 82% to 85% efficiency across typical loads. A single 92 mm fan provides quiet cooling, while active PFC and a single +12 V rail rated at 22 A ensure stable output.

Suits small-form-factor PCs with modest GPU needs

The single 6-pin PCIe connector supports entry-level graphics cards, and three SATA connectors cover basic storage. Builds requiring multiple PCIe power cables or higher 12 V current should consider a larger SFX or ATX unit instead.

Fits standard SFX bays

The 20+4-pin motherboard connector, 8/4-pin EPS connector, two peripheral connectors and a floppy connector cover legacy and current wiring. The 90 to 264 V input range allows worldwide use without a voltage switch.
