Download Datasheet

COM-HPC Server carrier is a general purpose carrier for generic COM-HPC server type modules typically used for prototyping purposes.

The carrier is an EATX size and can be mounted into standard EATX capable tower enclosures.

It is powered by off the shelve ATX type power supplies.
