PC not working?

[Valkyrius]

So, I've almost finished building my second pc after a very long time but I think something is wrong. I have all the components expect for the graphics card which is coming tomorrow. I tried to turn it on after fitting in all the parts, psu, mobo etc, just see if it the LED's work. When I switched it on it turned on for a split second then instantly turned off. It isn't connected to a monitor or anything, I just wanted to see if the LED lights would switch on. So I was wondering if there is something wrong or was it just the mobo noticed there wasn't a graphics card connected and switched off? When I try to turn it back on nothing happens. Fans dont switch on like before and neither do the case lights.

GA-F2A68HM-H
AMD FX 880k CPU
16GB DDR3 Ballistic RAM
Corsair 600W PSU
1TB HDD
RX 460 4GB OC (Isn't installed yet)
CiT Spectre Case

The case also came with a 4 pin cable which says "Power" on it, however there isn't anywhere on the mobo to connect it to. Could it be anything to do with this?

Thank you for reading, I hope you can help me find a way to fix this. 😀

I don't believe that CPU has integrated graphics. Also, make sure that your CPU fan is connected to the correct header on the motherboard. The motherboard needs that fan to be connected to the designated port.
