Server power supply module

This 1620W server power supply module delivers high-density power for rack-mounted systems. It provides +12V at 135A and a 5V standby rail at 4A. Active PFC and 80 Plus certification support efficient operation. The unit accepts 180-240V input at 50/60 Hz.

Suited for high-density server deployments

This module fits Supermicro chassis designed for redundant, hot-swap power configurations. It is not suitable for builds that require a standard ATX form factor or an input range starting below 180V. Systems needing lower wattage or different mechanical dimensions should consider other options.

1620W maximum power rating

The 1620W capacity determines whether this unit can support the combined load of processors, memory, storage and add-in cards in your configuration. Verify total system draw against this limit before purchasing. The +12V rail delivers up to 135A for the primary components.

Questions about this item

What does the 1620W rating mean for my server build?

The 1620W maximum power rating indicates the total continuous output this module can deliver to system components under load.

What does the 80 Plus label and 180-240V input range mean for daily operation?

The 80 Plus certification confirms high energy efficiency at typical loads, while the 180-240V input range means it requires a high-voltage circuit.

Will the 14.17" x 2.99" x 1.57" module fit my Supermicro chassis?

Those dimensions match the standard redundant power supply form factor used in compatible Supermicro rackmount servers.
