  • ATX standard simplifies integration into compatible systems
  • Plug-and-play USB 2.0 interface enables easy management

Server-grade 1600W redundant unit

This 1U power supply delivers 1600 watts with Titanium efficiency for dense rack deployments. It targets system integrators and data-centre operators who need hot-swap redundancy in a 76.5 mm wide chassis. The 27-pair connector layout matches Supermicro server backplanes.

27-pair connector compatibility

The single specification that decides fit is the 27-pair output connector pattern. Only backplanes wired for this exact pin arrangement will mate correctly. Verify the server or chassis documentation before ordering because an incompatible backplane will prevent power delivery.

Tool-less hot-swap installation

The unit slides into a 1U bay and locks with a built-in latch, so no screws or tools are required. A common error is inserting the module upside down, which damages the 27-pair interface. Align the guide key, push firmly until the latch clicks, then confirm the green LED lights.

Questions about this item

What does the 1600W rating mean for my server build?

The 1600W rating is the maximum continuous power the unit can deliver to your components, and the redundant design means a second module can take over if one fails.

How does the 27-pair connector affect compatibility?

The 27-pair connector is the proprietary high-density interface that links the supply to a compatible Supermicro backplane, so the chassis must support that exact pin layout.

Will the 76.5mm width fit in a standard 1U rack slot?

Yes, the 76.5mm width matches the 1U form factor, allowing the unit to slide into a standard 1U redundant power-supply bay.
