Is there some trick to getting these Pico PSUs to power on the motherboard that I'm just not seeing?  I have plugged the Pico PSU into the 24 pin connector on the mobo.  Plugged the EPS pigtail into the CPU EPS connector on the mobo.  Then plugged the 6 pin cable and barrel adapters together and plugged that into my server PSU's breakout board.  I get a blue light on the Pico PSU so it appears to be getting power properly... but when I hit the power button on my rig, nothing happens.  If I unplug the barrel adapter and plug it back in, I see the CPU fan spin for a second.  This is the same behavior you will see if you are using a regular ATX PSU and you pull and re-plug the power cable on it.  So it seems like everything should be connected properly... but it just won't power on.  If I remove the Pico PSU, and plug in a spare ATX PSU to the same 24 pin/EPS connectors, everything powers up just fine.  So, I know there is nothing else configured incorrectly.  My server PSU powers my GPUS just fine, so I know the server PSU  and breakout board works fine.


Also, Finsky... I sent you a couple of PMs about my previous order a few weeks ago.  I know you have been recovering from your disaster, so I've been patiently waiting, but if you could at least acknowledge that you got the PMs and what the plan is for fulfilling that order, I'd be grateful.



The way i did it was make my own cable till the 30” PCIe to EPS adapter assembly with barrel jack pig-tailed for powering Pico PSU (shown WITH Pico PSU connected, not included) - $6

are in stock ... is take one of these https://centrix-intl.com/details.asp?Parent2ID=1&productid=13186 and found a cheap in stock 10 pack of these on sell on Amazon https://www.amazon.com/gp/product/B01G0Q4422/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 and it worked but i see the 30” PCIe to EPS adapter assembly with barrel jack pig-tailed for powering Pico PSU are in stock now, but I see he not taking orders yet . so i have to wait and do what I came up with till then and can use my 1200 and 2400 watt server PSU, while i /we wait ....
