1U server power supply

The OIAGLH ENP-3927B is a 275W 1U form-factor power supply designed for rack-mount servers and workstations. It carries 80PLUS certification and active power-factor correction for efficient AC-to-DC conversion. This unit targets system integrators and IT professionals who need a compact, standards-compliant power source for dense chassis deployments.

Sustained-load behaviour

Under continuous operation the 80PLUS rating indicates the unit maintains its certified efficiency across typical load ranges without derating. Active PFC keeps input current sinusoidal, reducing harmonic distortion on shared power circuits during prolonged use. The 275W rating represents the maximum continuous output the supply is designed to deliver within its thermal envelope. Builders requiring higher wattage or redundant modules should evaluate alternative configurations.

Questions about this item

How much heat and noise does the ENP-3927B produce when running continuously at 275W?

The unit carries 80PLUS certification and active PFC, so it converts mains power efficiently at 275W, reducing waste heat and allowing the internal fan to run at lower speeds during extended operation.

What server chassis and cabling must I already have to install the ENP-3927B?

You need a 1U rack-mount chassis with a matching redundant power-supply bay and the correct motherboard power connectors for this 275W unit.
