You won't find a schematic.

How about $200.00 for a used one off eBay?  Note that this same power supply has 3 main searchable part numbers:

HP P/N: (aka HP Assembly P/N) = 480794-003

Spare P/N: (aka HP Spares P/N) = 508149-001

Delta DPS-1050DB A (with different revision numbers... the one I looked at on eBay is 03F).

These are custom engineered to significantly above and different from ATX standards including the shape.  The much more common (cheaper) version is the 850W one and I see one on eBay for 78.00 Buy It Now, free shipping.  Newer video cards and drives generally use less power these days and many Z800 workstations  get by with that one just fine.

Home grown attempts at repair/hacking risk your motherboard quite a bit.  Below is the 850W version.  The assembly part number might end with -001, -002, -003, -004 so you can search using those variations too.  I'd tend to go for the higher number version if more than one of those variations were available at same cost.
