1) Power Supply to Motherboard
2) Motherboard to Monitor

Motherboard has Processor, and Ram Memory on it.
Monitor cable plugs into I/O area on motherboard.
(Input/Output area. Where the Mouse/Keyboard/Audio ports, etc, are)

You can lay the motherboard on a piece of cardboard, then on the table you're working on.
Make SURE you are FOLLOWING Anti-Static Precautions. If you are not aware of what these precautions are, please post back in Comment.

To start the Power Supply, jump the two contact pins in the Front Panel header on the motherboard, with a small flat tipped screwdriver. (Jewelers screwdriver is the best for this)

(The front of your computer is the Front Panel.

The area of contact pins on the motherboard, that the main wires from the Front Panel go to, is the Front Panel header.
Main wires being;
Power On switch, Power On LED light, HarDDrive activity LED light, and Restart switch; IF your computer uses a Restart switch )

If that doesn't start the Power Supply, then use a jumper wire on the Green, Soft Power On wire, to ANY Black wire. ALL Black wires are Ground wires. (Negative connection)

The contact period is NO more than 2 seconds.

Bottom -> Users Manual UM_EPIA-M860_113.pdf

After you click on the above, a small window will come up on the right.
Make SURE there is a Green dot in the small circle to the left of -
Open with.
If not, click in the empty circle to the left of Open with.

[Should state Adobe Reader (default) in the box to right of Open with]

The Front Panel header is on Page 31 (Adobe Reader page number box at Top)

Two rows of contact pins.
TOP row is numbered EVEN.
BOTTOM row is numbered ODD.

Top row from Left to Right, is Pins 2, 4, 6, 8, 10, 12, 14, and 16.
Bottom row from Left to Right; is Pins 1, 3, 5, 7, 9, 11, 13, and 15.

Pins 6 and 8 are for the Power On switch.

{ Pins 2 and 4 are for the HarDDrive activity LED light.
Pins 10 and 12 are for a Reset switch, IF a Reset switch is used.
Pins 14 and 16 are N/C. Not Connected.
Pins 1 and 3 are for a Dual color Power On LED light.
Pin 5 is the Ground for the Dual Color Power On LED light.
Use pins 5 and 7 for a two wire Single color Power On LED light.
Pins 9 and 11 are N/C.
Pins 13 and 15 are for an internal speaker. The small speaker/buzzer for hearing BIOS Beep Codes ]

The main power cable is a 20-pin ATX main power cable.
General example of a 20-pin ATX main power cable, and it's respective connector on the motherboard,

You want the main power cable plugged into the motherboard, as shown in the photo to the Right.
The Green wire is the Soft Power On wire.
-> ANY Black wire is a Ground wire.

The preferred jumper wire is a straightened out paperclip, bent into a U-shape.
The top of the U is wrapped a few times with black plastic electrical tape. This taped area is for your fingers, and thumb to hold onto.

Turn the U shape over, and it is the 'legs' of the U that you are going to use.

One leg goes down into the socket hole, where the wires go into thew connector; RIGHT NEXT TO the Green wire, and slides down in.
Slides past the green insulation of the wire, and Touches a metal terminal at the End of the wire. MUST touch that metal terminal.

The other leg goes down into a socket hole, with ANY Black wire in it.
The contact period is no more than 2 seconds.

Power Supply comes on you have a bad Power On switch.
Power Supply does NOT come on; you have a bad Power Supply.

The Soft Power On circuit is 5 Volts DC.
In comparison two D cell flashlight batteries produce 3 Volts DC.
However, not stating that there may be a small spark, as you connect the U-shaped jumper wire.
For this reason you may wish to use a glove, on the jumper wire hand.

Cross-compile connections? I am at a loss.
Explain further in a Comment.

In which case change the monitor. I have checked the spec of the board and it has a VGA connector and should output to a normal VGA monitor. But your system is designed for Point of information and industrial automation. Try and find a display made for these purposes.
