I bought one MDD G4, found I needed a second one, bought the
second one a couple or three months later. Thereafter I used them
both, side by side, rather heavily. So both received virtually the
same use and they are almost the same age.
I put in new battery backups to address the possibilities you raised.
Some have suggested that the 400 W power supply was brought out as
a quieter system to address G4 noise complaints?
I am considering scrapping these G4's because used power supplies
on eBay are costing close to $150.00 with shipping. These power
supplies have a poor service record and a used one is a risky
investment. I presume that new ones are going to cost more than the
G4's are worth? National Ram Electronics will repair G4 power supplies
for $90.00 each and that seems to be the minimum cost to put the G4's
back in service.
Or you could convert generic ATX PSUs to work:-
