Flex-ATX 300 W power supply

This APEVIA TFX-AP300W is a Flex-ATX unit rated at 300 W maximum power. It fits micro-ATX slim cases and other small form factor chassis. A single 80 mm fan provides cooling. Input voltage covers 100 - 240 V at 50/60 Hz for worldwide use.

Builders with basic small-form-factor systems

It suits builds that need a 20+4 pin main connector, a 4-pin 12 V CPU lead, three SATA power plugs and two peripheral connectors. It has no PCI-Express power connector, so systems requiring a dedicated graphics card power lead cannot use it. No active PFC is included.

300 W total output with dual +12 V rails

The supply delivers 300 W across two +12 V rails rated at 11 A and 8 A respectively. Combined with +3.3 V at 21 A and +5 V at 15 A, this defines the power budget for the entire system.
