2 MOBO, 2 PSU, 1 Outlet Question

I have a circuits question to ask here.

I want to power up 2 motherboards with 2 Pico PSU using 1 outlet.

Checked couple forums, and found out how to power up 2 motherboards with 1 power supply using an ATX 24 pin splitter, and as long as I had enough Watts on the PSU to power up both motherboards it should be fine!

Now, I've been thinking in using 2 Pico PSU (one per motherboard), however I want to power all that using 1 outlet.

One would be a PicoPSU-120

The other one would be a PicoPSU-160-XT

As you can see, there's a ATX 4 pin connector for the power.

If I use a ATX 4 pin splitter to have only 1 power outlet to power up both PSUs, what would be the power adapter requirements???


I know it should be a 12V adapter, but now it would require more amperage to power up both PSUs.

What should be the power adapter specs to power that up? 12V, ???A, ???W?


I don't want to use 2 adapters since I'm trying to connect all using just 1 casing.

Would this be enough to power both boards? 12V, 8.5A, 110W?

Or maybe this one. 12V, 12.5A, 150W? -- Just didn't like the OEM adapter style :??: , but I can live with it!

Just want to make sure I won't burn the Adapter, PSU or the motherboard in this process!! :p 


Thanks a lot!! Hope to get comments and ideas on this!! :D

Hello, and welcome to THG.

Hmm, never thought of it. I will get back to you on this.

In the mean time, it may look as if your only bet is to power them independently.

I've been using it independently right now, since I don't want to buy the pico PSU until I know they'd work and not break the system! :p 

Wish I just had the money to get it and test it without getting worried of breaking it! hahaha

I'll be waiting on more comments in the meantime! :D
