 Many thanks for Reinhard Wolf for pointing me at SGI Document Number 108-0149-001.
 I will give a brief summary so that it will be in Deja News should anubody else need it.
  
 There are five power supplies available for an Indigo2:

     Suitable for Extreme, XZ and XL graphics on R4400 and R8000 machines.
  
 Part number: 060-8001-xxx
     Suitable for single-head (Solid, High or Max) IMPACT graphics and
     dual-head Solid/Solid IMPACT graphics on R4400 machines.  Can also
     be used in place of 9430814.
