Heat Dissipation Specs - Dimension 8400 vs 4700; Also: Whi..

Archived from groups: alt.sys.pc-clone.dell (More info?)

The spec I quoted for the Dimension 4700 power supply heat dissipation was
from the technical information on Dell's internet sales site.

Another spec for the same power supply says the heat dissipation for the
4700 is only 434.6 BTU/hour:

Anyone have any idea which spec is correct? There's a rather large
difference between 434.6 and 853, for sure.
