Please answer every Question. Looks like you are just testing the board without connecting a monitor,
Is this correct?
Is the MB on a insulated surface, like a piece of cardboard?
Is your PSU installed in the case? Is it switched on at the wall socket and at the back of the unit?
Are you taking anti static measure by, wearing an anti static wrist strap, or, briefly touching a bare unpainted part of the case before handling parts or working on the rig?
Have you connected two power cables to the MB,, the 8 pin and the 24 pin? see page #23, MB Manual.
Have you connected the CPU fan plug to the 4 Pin CPU fan header on the MB? Page #22, top, towards left of board.
Is the RAM in the correct slots? Slot #1 and slot #2, Page #16. NB. there is a gap between sticks. Ensure both locking levers at each end of the sticks is properly closed.

Thanks for the update.
Are the 8 pin and the 24 pin cables connected?
Do any fans start?

OK.
Check that the wall socket is working by plugging in a table lamp or other appliance, if working.
Swap the power lead with the one used for the monitor, > switch on at the wall socket, > switch on at the back of the PSU, any fans spin?

I just tested my psu using the paperclip method and it works fine.

Good, shows the PSU is receiving AC power but, does not test tit under full load. This can only be done with a PSU tester. Some local stores/repair shops will do this for free or a small fee, so if we cannot get a good result you may have to do that.

You can try the paperclip test with the PSU under partial load. Please ensure the PSU is turned off.
Connect up a HDD, power cable only.
Connect up 1 or 2 fans, 4 pin Molex cable only.
Switch on the power.
Can you hear anything from the HDD? do the fans spin?

Good, shows there is output from the 12v rail.
We need to know the brand/model of the case please to know what leads/plugs go to the LEDS and switches on the case front.

Thanks.
Downloaded the manual, can find no mention for the control cables/plugs for the front panel.
Is this the plugs you have? > https://www.google.c...tml%3B620%3B315 If yes.


Please do the following with computer turned off.
Remove the test paperclip.
Disconnect power to the HDD. Please leave the fans connected.
******
Connect the Power switch, The Reset switch, The Power LED. The Mini system speaker.
Switch on the PSU, > watch for lights on the case and press the Power on button.
The fans should spin up and you should hear a beep code. let us know what the beep code is, IE. one long, two short.

Gday.
Sorry at has been a laborious process. Even though the result is good, it not being possible to actually test completely the PSU, chances are it is good.

Q.
Did you see activity lights on the case?
Do you have a How to Build tutorial?
what type of HDDs are you installing and how many?
