To sum it up:
- 1st the 4 disks on the Jmicron controller failed with 1 [chieftek] PSU
- then it failed with 2 PSU too, but this time the chieftek was only
   connected to the different 4 disks - on the nvidia controller. MB
   and other disks were on the other, non-chieftek [650W] PSU.
- Then I started the tests with only this second PSU, and it ran
   for about 6 days under heavy testing and array rebuilding and
   guess what: it failed again.

Since it is not a "switch on and see" problem, I'm not in too good
position, so unless someone have a really great idea or observation,
I seriously have to consider to replace the MB and probably add
some extra sata controllers.
