What power supply is needed for the Gigabyte GA-H77TN motherboard with DC Power Jack?
I liked this motherboard: Gigabyte GA-H77TN
www.gigabyte.com/products/product-page.aspx?pid=44...
1 x mSATA connector (for mSATA SSD)
1 x Mini PCI Express (for Wi-Fi module)
I only found in the manual about the connection: Connect the DC power to this port.
The board also has the following connectors: ATX_19V, DC_IN, SATA_PWR 150W

AC Universal Adapter 12V 12.5A with 2.5/5.5mm DC Power Connector
www.mini-itx.com/store/psu?c=10#150W-AC
12V DC Input, will it work with this board? - it seems not.
Then already M2-ATX is a wide input (6-24V) but it has its own DC Power Connector and a full-size ATX power cable, which is not needed here at all.

Googled that there are other chargers for HP Original 19V 7.89A 150W AC Power Adapter laptops, can it fit this board?
How can I figure out what is needed to power the board with and / or without peripherals.
The power of the block is about 120-150W because there is already a processor with a 55W heat pack.
What is ATX_19V for and what to connect there? ATX_19V connected somehow with DC_IN?
Thanks everyone for the replies. Now it is clear)

Good afternoon.
Sorry for the belated reply. I myself encountered such a problem (motherboard Gigabyte GA-H61TN). Case for ITX but PSU standard ATX, power 300W. I launched the board from a standard built-in PSU, while temporarily and "on snot" (just checked the work). On the weekend (I'm waiting for the package) I'll solder the ATX power supply control circuit and write off the results.
