Questions about this item

How much heat does the Optiplex 790 SFF motherboard D28YY produce when running all day?

The board is designed for the Optiplex 790 SFF chassis and its original cooling solution, so sustained heat output matches the system's factory thermal envelope.

What existing parts must I already own for the D28YY motherboard to work in my Optiplex 790?

You need the matching Optiplex 790 SFF case, power supply, processor, memory modules and front-panel connectors that originally shipped with that model.

Will the D28YY board fit and function with older components I kept from a different Optiplex generation?

This motherboard is keyed to the Optiplex 790 SFF platform only; it will not align with mounting points, power headers or front-panel pinouts of other Dell generations.
