Entry-level 300 W ATX12V 2.2 unit

The Foxconn HH-400UNEA delivers 300 W through dual +12 V rails rated at 11 A and 15 A. It targets basic office builds or replacement jobs where a PCI-Express power lead is not required.

Fixed cable set shapes installation

A 20+4 pin main connector, one 12 V P4 lead, three peripheral plugs, two SATA headers and a floppy connector are permanently attached. The non-modular layout means unused cables stay in the case and must be routed around other components.

ATX12V 2.2 spec caps expansion

The 2.2 standard limits combined +12 V output and omits native PCI-Express power, so graphics cards needing a six-pin or eight-pin feed cannot be used. Input range covers 115 V and 230 V at 50/60 Hz for worldwide mains compatibility.

Questions sur cet article

How long is the unit rated to run before a failure becomes likely?

The mean time between failures is rated at more than 100,000 hours of operation.

Which rail hits its current ceiling first when the load stays high?

The +12V1 rail is limited to 11 A, so it reaches its maximum before the +12V2 rail at 15 A.

How much heat and noise should I expect from the single fan during continuous use?

With a 300 W maximum output and one non-modular fan, sustained loads will push the fan to higher speeds, increasing both airflow noise and exhaust temperature.
