The +5V rail might have been used on this machine for the CPU, but on
modern boards, I think it's actually one of the +12V rails (that's the
little 2x2 connector).  One of the appropriate hardware standards (can't
recall which) specifies such that this connector uses a different rail
(in multi-rail systems) than the PCI-E power connectors to help balance
the high draw devices out better.  For example, on my desktop, the CPU
is on rail 1 and each PCI-E connector is wired to split the load across
rails 2 and 3.  The +12V rails have a PCI spec limit of 20amp max per
rail, so this is required.
