900W Platinum AT Power Supply

This 900 watt AT power supply is built for IBM System x servers that demand high-efficiency AC power delivery. It suits data-centre administrators and IT teams maintaining compatible rack-mounted systems where platinum-rated efficiency reduces ongoing energy costs.

Platinum efficiency at 900 watts

The single specification that determines fit is the platinum efficiency rating combined with a 900 watt output on an AT form factor. Only systems designed for this exact wattage and efficiency class should use the unit; mismatched power budgets or form factors will prevent correct operation.

Direct replacement in compatible bays

Installation consists of sliding the unit into the designated power-supply bay and securing the latch, a process that requires no tools in supported chassis. The most common issue arises when the server model or backplane does not match the 94Y6667 part number, leading to mechanical interference or missing power connectors.

Questions about this item

What does the 900 W rating mean when this unit is installed in a System x server?

It delivers up to 900 watts of continuous AC power to the server components, with platinum-class efficiency reducing waste heat under load.

How does the AT form factor limit the power this supply can provide in practice?

The AT design matches the server's power-distribution board, so the 900 W rating is the practical ceiling for that chassis.

What physical space and mounting does this internal 900 W supply require?

It occupies a standard hot-plug power-supply bay in compatible System x chassis and secures with the built-in latch.
