Help connecting PSU

[algag85]

My motherboard has a 24 pin connecter and 4 pin and my new PSU has a 20+4 connector, but not another 4pin just a bunch of 6 pins. If I start it with just the 24 it starts but doesnt post. I am able to plug the 6 pin connecter into the 4 pin slot but when i tried the computer wont start at all. Do i need to buy a new power supply with an extra 4 pin connecter or can i make this 6 pin work somehow.

What PSU is it?

i would think psus should normally have both pins, because the 4 pin one powers the cpu in mid and upper end builds(even many low end builds). unless the psu is extremely outdated that is, or is cheap.
