Here is my build i am working on. so far i have the motherboard in the case with the processor / cooling unit, USB 3.0 & 2.0 plugged in, power supply screwed on and plugged into the mother board, RAM is installed too.

Essentially i do not have my HD or SSD or CD drive or my graphics card.. but i wanted to see how it sounded so i plugged in the cord to the supply to a wall outlet and attempted to start it and got nothing. Please advise if I need to finish putting everything in or if i screwed up, lol. Thank you

Two simple questions to start off.

1. Is the 8-pin CPU power connector cable plugged in?
2. Is the 24-pin motherboard power connector cable plugged in?

24 yes, 8 i do not think so... the only thing plugged into the mother board from my power supply is the 24 pin

Check the manual for the required power connections for your mobo.

You can test if your PSU turns on without a load by shorting the Green and a ground (black) wire. If the PSU doesn't turn on when the green/black wire is shorted, the PSU may be dead.

Do you need me to say it explicitly? Plug in the 8-pin CPU power connector and try again.

PLUG IN THE 8-PIN AND OTHER AUZ CONNECTORS.
Mobo's will not turn on if there is not enough power or as in your case, no aux connectors.
