The Dell Poweredge R810 can hold up to 2 power supplies. The spare power supplies come in only 1100W options. Make sure you are replacing or adding an additional power supply that matches the wattage of the current power supply installed. Always replace with a genuine Dell power supply specifically engineered for the Dell Poweredge R810.
If we are not showing stock contact us at 952-831-1032 as we most likely have in servers that we can pull the power supply from.
