Is my new motherboard compatible with my power supply??

The cpu cooler plugs in to a 4 pin fan header [ usually on the top edge of the mb near the processor ]

The power supply connects to the mb via two cables . One has a 20 +4 connector .

The second supplies power to the cpu and it is 4 pin , 4 + 4 pin, or 8 pin .
You have the 8 pin. It only fits one way .

4+4 just means that your power supply could be used on older boards with just 4 pin power requirements but on the newer boards that want 8, you can combine them side by side and make it all happen still (or 8 pin power).

So you will be able to do this as long as your case can fit the board because EATX is Extended ATX and larger physically in size.
