I just got a new PSU but the 24 pin ATX is a 20+4 connector
My mobo needs a 24 pin connector but im not sure if it is supposed to use the extra +4 to make it 24 pin or if it is just supposed to use the 20 pin

Mobo:Gigabyte GA-78LMT-S2
 
Yup thats what is is for. The Pre-2005 PC's used 20 Pin's and after use 24. Depending on the PC some will still take just a 20 pin but most PC's need the 24 pin for the extra power. But that is why its a 20+4 pin so you can use either 20 or 24 pin.

That's impossible unless there is actual damage. It should fit into place completely.

No because the pattern on board would need to match exactly how it is on the pins. if you look there are squares and half-circle looking shapes that create a pattern for it to fit into.

Also do SATA cables go in a specific way?
 


see how that tab it on top of the 20 pin that is on the 4 pin? Suppost to go on bottom. Maybe try putting in the 4 pin first then the 20 pin. Will fit the right way then.
 
Also SATA cables only go in one way. They are shaped like a side ways L. some 90 degree angle ones are different depending on the case. Like normal 90 degress will point down inside the case. Some OEM's like Dell and HP might make ones going the other way because of how hard drives are mounted sometimes in their case.
