  • 870 watt redundant output keeps PowerEdge R710 and T610 servers running if one module fails

  • Dell 3257W part number matches the original specification for direct replacement
  • New condition delivers full rated performance straight from the box

870-watt redundant server supply

This 870-watt redundant power supply carries Dell part number 3257W and is built for the PowerEdge R710 and T610 platforms. It delivers 870 watts in a hot-swap redundant design so a second unit can take over if the first fails. The unit is supplied new and matches the original Dell specifications for those servers.

Fit for R710 and T610 redundancy

The supply suits administrators who need a direct replacement to keep an existing R710 or T610 running with full redundancy. It will not fit servers outside the listed compatibility, so builders working with different chassis or wattage requirements should look elsewhere.

Questions about this item

How much heat does the 870 watt redundant power supply generate when running continuously in a PowerEdge R710?

The 870 watt unit draws up to 870 watts from the mains under full load, so nearly all of that power becomes heat inside the server chassis; ensure your rack airflow matches the Dell thermal specification for the R710.

Which server chassis and backplane must I already have to install the 3257W redundant power supply?

The 3257W is keyed for the PowerEdge R710 and T610 redundant power bays; you need one of those chassis with the matching hot-plug backplane and an empty bay.
