Yo,
I get where you guys are coming from.  But I suspect the fuel PSUs are actually very fixable.  I’m no expert, but I was working on the theory (from remembering reading Nekochan cases) that the output voltage is slowly walking out of tolerance (I believe upwards), on at least the 5V rail. 

I suspect this is a major contributing factor to health monitoring disease. The stated voltage tolerance in the Dallas chip data sheet is like 5.75V and I think the L1 warning begins at like 5.8V?  I’m pulling this from memory here.  I thought I remember reading people’s L1 monitoring output claiming 6V and higher for the 5V rail as it went. 

And I think that becomes worse and L1 tries to protect the main board and eventually the PSU voltage is so high, it’s just whack and dangerous to the main board. 

I thought the ATX solution didn’t have the logic lines to control the PSU correctly from Irix and the L1?  That’s kind of suboptimal to me.  Great if you have no choice/recourse. 

I understand concentration, I have Indigo2 supplies right now with no-power symptoms to look into.  Though I can’t find the really high end Indigo2 PSUs, so that could be a bigger issue. 

I’m simply asking for PSU examples from everything I can get.  I know the Fuel PSUs have a failure profile and I’d prefer the intended functionality of the original supply in anything I collect, when possible.

So while I appreciate your response, I must still request that if anyone has a failed PSU, that they don’t mind parting with, to please contact me.

Thanks,
