What is the PCU of an aurora?

[tera-pixel]

I have an Alienware aurora and I can’t find any information concerning the PCU all I have found is by opening it up but I think this may infringe on my warranty.

The only reason to know your PSU (Power SUpply Unit, if this is what you call PCU) is if you want to upgrade something inside, and you'd void warranty anyway.

Unless your PC has a warranty seal on the covers, there's nothing to stop you opening the cover and inspecting innards.
