PA on Penny is rated at 12v so running on 13.8v is cause to let the smoke out.

<TD vAlign=top><BR>One thing I forgot to mention was is that when I set
mine up for use with the standard shack 13.8V power supply I added two
series diodes to the input lead to the PW-200-M. I did that because the
+12V supply from the PW-200-M is fed straight through from the power
source. Not sure if doing that was truly necessary or not, but it
made me feel better.<BR><BR>Duane<BR>N9DG<BR><BR>--- On <B>Sat, 4/9/11,

that I purchased in the 2007 time frame. I have not noted any
noise from it while running either the Janus/Ozy or
Mercury/Metis board combinations. I should note though that I
have not loaded it any heavier than those two board
combinations, so if there is an increase in noise as the load
goes up I would not have seen it yet.<BR><BR>That PS comes with
a pig tail connector for various HD types, I simply un-soldered
those pigtail leads. It directly plugs onto the Atlas power

start a search for electrically quiet ATX supplies, I thought
I would verify that Atlas is fully compatible with PC ATX
supplies. The goal is to prevent a toasted
system.<BR><BR>One more question: A document generated
in 2006 shows an Atlas with a PicoPSU ATX power supply.
Has anyone recently used one of these?? How quiet are
they from an electrical/EMI standpoint?<BR><BR>Any other
