While that can be true, Ralf, switching psu's can be a problem, but 
they've been 10000% better

than any magenta drive cable, which has about a 2 or 3 year lifetime. 
One popular psu maker

seems to design for an old age drift low, that seems to rare its head as 
low voltage just weeks

after the warranty expires.

I've had much better luck with 300 watt rated $12 USD supply's bought 
from china in lots of 24

than with name brand stuff since the late 1980's.

Cheers, Gene Heskett, CET.
