2U Single 650W Server Supply

The Athena Power P2G-5650V is a 2U form-factor server power supply rated at 650W maximum output. It delivers +12V at up to 50A alongside +5V and +3.3V rails at 25A each. A single 60mm DC fan provides cooling across the 0°C to 50°C operating range. The unit accepts 90-264V AC input at 47-63Hz for worldwide rack deployment.

Suited For Chassis Integration

This supply is designed for chassis-assembly only and must not be operated as a stand-alone component. Final assembly must comply with applicable EMC and safety regulations. Builders needing redundant or hot-swap power modules should consider alternative configurations. The single-unit design fits 2U server, workstation, storage and IPC chassis where a single 650W source is specified.

80-84% Typical Efficiency At 115V

Efficiency reaches 80 to 84 percent typical at 115V input under full load. Hold-up time is a minimum of 16ms at full load and normal input voltage. Protection circuits include over power, over voltage and short circuit protection. Dimensions measure 9.45 x 3.94 x 2.76 inches for standard 2U mounting.
