[hpsdr] Atlas ATX Connector Fully Compatible with PC ATXSupplies?

[Phil Harman]

Hi Duane,

Not only is it necessary it's essential!  The PA on Penny is rated at 12v so running on 13.8v is cause to let the smoke out.

        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.

                I have been running the Mini-box PW-200-M 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.

                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 connector.

                  Before I 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.

                  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?

                  Any other suggestions?
