I recently tried to upgrade my rig into a new case and i had to get an mATX motherboard. But it wont power on, i didn't get new hardware other than a Corsair H100i V2 and the new motherboard.

Case: Previous Corsair Spec Alpha, New Corsair Air 240
CPU: FX-8350 Wraith edition
PSU: Previous EVGA 450B, New CX430
RAM: Corsair Vengeance (DDR3 1600 Mhz, 2x4 GB)
HDD: WD Blue 1TB (windows 10 installed already from previous build)
Cooler: Corsair H100i V2
Motherboard: (Previous BIOSTAR TA970 Ver. 5.3, New gigabyte GA-78LMT-USB3)
Case fans: 2 AF120 Corsair LED Purple, 2 SP120 Corsair LED Purple (mounted on the radiator)

I've double and triple checked all the connections are secure and connected properly. I've tried pulling the GPU and plugging in directly to the motherboard, and also attempting with no RAM (to see if i could get any status beeps) nothing. Transferred all parts back into old case to ensure if they weren't damaged it booted no problem. Any help would be much appreciated and thanks in advance!

Unless you attached the speaker to the motherboard, you wouldnt get any audible feedback. Did you attach the piezzo speaker that came with the MB?

Make certain your RAM is compatible with the bus speeds of the MB.

I noticed looking at the specs, that one MB is 120 Watts, and the other is 140 watts.

Look at the specs.

Sorry for the late response I've been busy, I'm not entirely sure how to check the wattage for the slots on the motherboard of the gigabyte

Im telling you, the specs on the documents have a different specification. I am not 100% certain that you can swap wattages on CPUS! ONe is 120, and the other is 140.
