could it make it not power up at all ?
Anyway I tried this, but it didn't help: the PSU still won't start (the fans
don't spin up, and no significant voltage comes out on the disk connectors).

The power cord is OK, I connected a PC to it to test (and tried 2 known-working
cords). Do you know what voltages these pram batteries are supposed to
deliver ? here I have about 1V, which looks way too low. But it should be
possible to connect standart batteries (at last for testing), the batterie
connector isn't that special.
