New Built PC wont work

[Takashi-san]

My new PC wont work. When I turn on the power switch, none of the fans are responding. Right now there is no graphic card or monitor yet because it is being shipped. I'm fear that one of the parts might be damage so if anyone can please help me, I would VERY MUCH be appreciated!

Processor: Intel I5 4670k

Power Supply: Corsair CX750

RAM: Corsair Vengeance 8 GB (2 x 4 GB)

If anything else,

Most important thing, make sure the power button from your case is correctly connected to the motherboard. You'd be surprised how easy it is to put that one pin over and have everything not work. Next make sure your PSU is properly connected to your motherboard. Forcing an 8-pin GPU PSU connector (the 6+2 pin connector) into the motherboard would be very bad for example 😀. Make sure you have the 8-pin for the motherboard from your PSU properly connected.

Also make sure your RAM is properly inserted. You may want to test it with one stick at a time and try different slots just to be sure it isn't the RAM or the RAM slot

I did what u told me, recheck the wires to the mobo and reinstall the ram. Nothing working so far :c

If you're not getting any response whatsoever and you're wiring is correct to the mobo header, check the power switch on the back of the PSU, i've gotten one before that came out of the box in the off position.

The switch with the " I and O"? I switch both of them, nothing on :c
