>> Power supplies for Atlas have been discussed many times and board current
>> measurements (except for Mercury at the moment) have been posted. No
>> problem
>> for bringing it up again. The design of Atlas to use a standard ATX
>> connector and place boards on PC slot spacing for 'cabinet' purposes were
>> discussed extensively prior to Phil Covington finalizing Atlas.. Check the
>> HPSDR archives all the way back to Xylo Group for earlier work on Power
>> and
>> Atlas design.

>> There are numerous articles posted on the Web for using and taming ATX
>> power
>> supplies for bench supply use. Note on most supplies (Not PicoPSU) you
>> will
>> need a 10 ohm 10 watt resistor in the 5 volt line to provide load to keep
>> power on the outputs.

>> Also Scotty - WA2DFI TAPR has extensively used the PicoPSU to power and
>> test
>> the various boards. The Pico PSU was somewhat crudely tested in the early
>> going and found to be pretty quiet on the buss. If I remember correctly
>> there was some short range 'radiated' rf noise. So far it handles a
>> reasonable number of boards. Mercury will probably bring a new definition
>> to
>> the word Sensitivity, and Phil Harman and other alpha testers will be
>> testing the Mercury Alpha with PicoPSU to see if there are any issues.
>> Since
>> the 5 Mercury Alpha's are on the way to the testers, we should know in a
>> week.

>> Apologies if this has been covered before - have googled etc.

>> Is there a current preferred psu to use for Atlas etc? Am about to plug
>> in my home-assembled Atlas and all available boards but slightly scared
>> I might blow the whole thing with a bad solder joint. All looks good but
>> recent mention of 'over-voltage' protection etc makes me a little scared
>> of using a standard PC psu / flicking the on switch.

>> What's the current psu of choice for you guys that have up and running
>> systems?
