Are the front panel connectors (PWR BUT, etc.) able to be turned on from ONLY the 24 pin being plugged into the mobo from the psu and being turned on? I just tried that to test if the pwr button LED would come on but it didnt. Was i missing a cable to make it come on, do i just need to wait until i do my full build, or should i be concerned about something being wrong with one of my parts?

you will need the 4 pin plugged into the motherboard (blue 4 pin) directly above and to the left of the CPU. that is the aux power line for the CPU. now you are powering the motherboard and part of the CPU which is why nothing happens.

no the front panel hardware (LEDS,reset switch, power switch) need to be hooked up to motherboard. the 24 pin is the power supply header. think of it this way, you need the ignition (key) wired or the car won't start. the power supply is listening to one of those wires (power switch-key) to tell it to come on. you could also start the pc without a switch by shorting (bridging the two power switch pins with a conductor momentarily-hotwiring) the pins to turn on the system.

Yes I have all the front panel connectors plugged into the motherboard in (im sure) the right places, along with just the 24 pin. but nothing activates. I can see the led on my motherboard come on when i switch on the psu so i know the motherboards getting power.

do you have the 4 or eight pin aux power cable plugged into the motherboard?
which motherboard, then I can help more.

sounds like the front panel is sorted, try manually shorting the pins, just to make sure.

I thought the 24 pin powered the mobo and the cpu cable powered...well...the cpu. But I guess i was wrong, its my first build. But thank you for answering, you the real mvp, homie.
