You must connect the power supply's ATX_12V cable to the individual 4-pin connector (#19) on the motherboard.
If you have a 20-pin + 4-pin main power supply cable, do not attempt to connect this 4-pin cable to the #19 connector.
The correct ATX_12V power cable will have 2 black wires and 2 yellow wires at the connector.
See the attached chart for the standard wire colors for each of the 4-pin connectors.
You will need at least one memory module installed in the correct slot for your system to post and boot.
Looking at the 196 page quick installation guide, I did not see a case speaker connector on the motherboard so you won't hear any beep error codes unless your motherboard has a built-in speaker already attached.
Post the model numbers for each of your power supplies and links to the specifications for each psu.
If you are using power supplies that are too old, this might be part of the problem.
A good quality 300 watt (or higher) psu should be fine.
Test your motherboard with it resting on a cardboard box beside your computer case.
Do NOT connect the RESET switch to the motherboard until your system is able to boot.
A faulty (always ON or shorted) RESET switch will prevent your system from booting.
