Power for Basic Builds

The In Win AJ Series IP-P300AJ2-0 is a 300 W ATX12V 2.2 power supply designed for standard desktop computers. It delivers reliable energy for office workstations, home PCs or light productivity systems. This unit suits builders assembling entry-level configurations where high wattage is unnecessary.

300 W Maximum Output

The single specification that determines compatibility is the 300 W maximum power rating. Your components must draw less than this figure under full load to avoid instability or shutdown. Systems with dedicated graphics cards, multiple drives or high-end processors will exceed this limit and require a higher-capacity unit instead.

Thermal Fan Speed Control

Under sustained load the Noise Killer feature adjusts fan speed according to temperature, keeping airflow proportional to heat output rather than spinning at a constant maximum. Protection circuits guard against over voltage, over current, over power and short circuits, while a re-settable shutdown prevents damage during prolonged stress.

Questions about this item

How much continuous power can the 300 W rating deliver to a typical desktop build?

The 300 W rating is the maximum combined output across all rails; a typical office or entry-level desktop with integrated graphics will draw well within that limit.

What does ATX12V 2.2 mean for motherboard and CPU power connectors?

ATX12V 2.2 specifies a 24-pin main connector plus a 4-pin 12 V CPU connector, which covers most mainstream boards from that era.

Will the single-fan unit fit a standard ATX case without extra brackets?

Yes, it uses the standard ATX PSU form factor and mounts with four screws at the rear of any compatible chassis.
