Specifically, per the power switch and reset switch if wanted:

The PSU, when switched on on the back of the PSU only supplies "stand by' power.

It's a cases power switch , and its wiring connected to the MB , that actually turns the computer on for use.

Without the cases power switch being connected to the MB, no, it will not turn on.

Xaltar explained above how to short the two power switch pins, which will act the same as a cases power switch.

Being very careful not to short out any incorrect pins at the system panel header, if you have the nerve, give that a go.

I don't have a case, as I plan to build one out of Legos. Let me see if I understand you so far.
 
You're telling me that the psu acts more like a power strip, and to turn the device on, I have to use a separate switch entirely, a switch, that is usually supplied with a case purchased from any retailers, so in order to get the computer to post, I'll needs second switch in the same way I would if I had a tv plugged into a power strip?

OP, in your MB Manual(I just used the online pdf  manual), see pg 5, Sec 1.3, specifically the lower right corner, #12. This is where the wires FROM the case are connected.

Then refer to page 17, System Panel Header< for which wires from your case attach to the MB at this location.

If you need further help, reply back with your cases make and model. We'll know more towards guiding you then with us knowing the case you have.

You're seriously telling me the problem is i have no "on" button?

I know it sounds bad but yes Wink

The power switch from the case needs to be connected to the motherboard. On your particular board the connector you need is on the bottom left corner of the board if you look at the board with the IO panel at the top.



I have highlighted in red where the power switch is connected for you. If you do not have a case or just want to see if the system will power on you can short those 2 pins with a metal object, I usually use a screwdriver. 

I hope this helps solve your problems Smile
First builds can be tricky but you will feel great once you get it all up and running Wink

A jumper is a little plastic square on your board,its on the very bottom.first thing on the bottom left......a little plastic square covering the first 2 pins out of 3 pins....if the square is covering #2 and #3 pins,thats CLEAR CMOS,and board wont fire up.
If the square is covering #1 and #2,that is not the problem here.

what hes saying is,,wrong switch,,,power supplies have their own switch,that does not power up computer,more like a emergency kill switch......to power computer the power switch/button is on the case/tower,most likely the front of case.
