Can i hook up my Pc just to check fan's etc without CPU and Ram?

Hi guys!
Currently in the middle of buying stuff for my Gaming Pc, Still to get my cpu and Ram, But today i just wanted to actually take the stuff out of packaging and put it in the case and power it up connect most of the wires etc and then plan everything else still to do!
I will be getting the CPU and Ram in 2 Weeks time! Would it be okay if everything was in the Pc and power was turned on for like 1 Minute just so i can see the LED fan! ?

I know it will be abit tricky to get the CPU in once everything is in before it, But if that's the case i can take it all out!

Thanks guys?

If curious my CPU is the 8320 and Ram is 8GB of Corsair Vengence!

    The power button on your case connects two pins on the motherboard, which then causes your power supply to come on.
    The motherboard won't respond to the power button if there is no CPU installed.
    If you want to test a fan, any DC 12V supply can power it for you.
  2. As far as im aware the PSU wont power up without the CPU installed but you can try. It wont do any damage but the computer will not boot. Also DO remove the motherboard before installing the CPU, if you bend a pin its a nightmare sorting it out (also depending on board and CPU some have a back mount bracket on the board).

    Ah so the Motherboard is Useless until the CPU is installed in a easy sense?
    And just to add another, Is there anypoint putting the parts into the case at the moment just to gain abit of experience and then add the CPU and Ram later. I know its A bit weird lol but it will keep me Enthusiastic i think is a good word about my build?

    Thanks man :) Yeah, I already checked for a back plate, Don't think it's needed!
    The urge just to build it is unreal!

    It is much easier to install RAM and CPU in the motherboard before you install it in the case.
    What you can do before then is look where the motherboard is going to sit and where the power connectors will be, then see how you are going to route cables.

    Yeah, Sound like a good plan. Also while you are around, I noticed your Power Supply master tag!
    This is my first build, Noticeable much!
    I have a Corsair 500W power supply and my GPU is a 7870 TL which requires 2 6Pin connector's, I looked at my PSU specs and it said it had One 8 and one 4 connectors? which would make 12, Could i connect there to my GPU or would i need an adapter, The Guy who i bought the GPU said he has one if i needed it! Thanks
    Hard to explain due to being a novice but hopefully you can see where I m coming from.

    The supply should have dedicated PCI-E connectors.
    The Corsair CX500 has two 6+2 pin PCI-E power connectors, which means these have the two extra pins separated from the 6 pins so that you can use these with a 6-pin or 8-pin connector on the graphics card.
    There is another 8 pin power connector for the motherboard. The plugs are different so that you can't put these in the wrong socket. If it doesn't fit, don't force it.
