I have a GSE supply for my system.  First of all, the power I get out
of this unit is a couple of magnitutes cleaner over the old GS

run my accelerators 1-2 mhz faster with greater stability with the GSE
vs the Apple ones.  Its a heck of a deal for $55.

Agreed.

As far as heat dissipation, I disconnected the integrated cooling fans
(I'm not a fan of fans).  The GSE supply actually runs hotter than
stock this way, probably due to it being a switched supply rated for
200W and designed with an integrated fan.  If it was a 60w rated
supply, it would probably run significantly cooler than the GS's.
However, with the fans turned on, the case doesn't even get warm.

Interesting.  The only mechanism for dissipating more heat because
of excess "headroom" is larger core losses in the switching transformer
because it has a larger core, plus consequently higher switching
transistor losses.  Everything else should dissipate heat only as
a consequence of actual supplied power.

An argument against overkill in internal power supply capacity. ;-)
