And my motherboard has several seperated connectors, including one that even has a cover for half its pins. This is very different from my different motherboard and the manual doesn't really help in this regard. This is the mothreboard btw
What power supply do you have there? I cant tell if it has a 20+4 atx connector or a 20 pin connector and a 4 pin connector. If you dont have a 24 pin connector on your power supply then it is definitely time to upgrade. If that is a 20+4 pin connector then it goes in the 24 pin slot on the motherboard and there should be another 4 or 8 pin connector that goes into the 8 pin slot that has half the holes covered.
That is right. As the MB picture shows, the 4-8 pin socket at the right edge of the board is where the 4-pin goes. They have blocked off the other for pins for you so you won't get confused... if you had a newer PSU with an 8-pin cable you would just remove the tab.
In short, fill every power connection on the board that you can.
Thanks for the help guys, everything is working fine. I had a little scare with some red lights on the mobo but apparently they are normal for a first time boot, it's some sort of boot up check for all the components. They are all gone now.
