Hey, thanks for the link. What gets to be about that diagram is the
12v power connector near the CPU has 10 pins and I haven't seen a 10
pin 12v connector on any power supply I've looked at so far. They all
have been 8 pin. Anyone know anything about this or work arounds such
as adapters?

If you look at the docs, the supply looks like it has three 12V rails.
The 2x5 connector, seems to be a 2x3 next to a 2x2. Half for the
processor and half for something else.
On this page, is says the power supply is 650W:

An 840EE would draw 130W. That is 12.03 amps at 12V when the Vcore
converter is 90% efficient.

A pair of 7800GTX would be 80W * 2

While the 512MB card in this example, is not the same as the
256MB card, the card draws 12V @ 4A from the video card slot
and the balance of the card power comes from the PCI Express 2x3
connector. But in terms of total current draw, a guesstimate would
be that the 160W is all coming from some +12V rail. That would
be 160/12 = 13.3A.

So far the total is 25.3 amps from the 12V rails. Maybe call it
28 amps with a minimal hard drive and CDROM. You can compare that
number, to whatever is printed on the side of your 650W supply.
It is always possible the three rails are poorly split, to cover
the loads. But judging by the weird choice of what is connected
to a, b, and c output, I'd say someone has tried to balance
the loads somewhat. (The choices made don't look to be the
same as an off the shelf supply.)
I don't have a picture of the label on the side of the
supply, so you'll have to guess as to whether the supply
is adequate or not.
To build a custom to take the place of that power supply,
you'd need room in the case for a standard form factor ATX
supply, plus additional room for the added length of monster
power supplies (they are longer than normal), and then you'd
need a pin puller and a collection of nylon shells, to try
to build a replica to the a,b,c wiring pattern of your
XPS600 supply. Minifit Jr shells come in all sorts of sizes,
but the pictures on the Dell web page don't show the shape
of the individual pins - that would need to be checked to
make sure a regular shell might fit the 2x5 hole pattern
used on the motherboard.
