The collected works of sunbeam477

Hi I am new to this board and SGi in general. I have an indigo 2 not powering on (no led, fan movement or anything) and am curious as to whether the power supply for an indigo 2 with impact graphics is proprietary like most other SGi stuff or if there are generic PSUs out there that will work with this system. I have read Ian Mapleson's reconditioning failed PSU article but I am not interested in messing with capacitors just replacing the PSU. Any opinions are appreciated.
