I have recently bought a Corsair VS 550w ATX psu and I have a gigabyte GA-F2A78M-HD2 micro ATX FM2+ I’ve plugged in most things but it won’t turn on. It’s all compatible and fits but I don’t understand why it won’t work

Make sure you have the 24pin and the 8pin CPU connector plugged in. Also, if those are both plugged in make sure the PSU switch on the back is turned on.

On your case there will be a a wire that has several small ends labeled Reset SW, Power SW, HDD Led,etc. They will plug into your motherboard header located on the bottom middle of your motherboard. There is a small diagram underneath the pins labeling the designated plug plug each of those wires onto the correct pin.
