I didnt realize that my PSU doesnt have a 2x8 pin. I was just wondering if its okay to use a 2x6 pin in place of it?

What is this connector for?
Do you mean 2X4 pin for the EPS 12V connector? Are you referring to Pcie connectors?

Looks like the PCI-e connectors but instead of 2x6 its a 2x8 on the motherboard. just wondering if I could use the PCI-e (2x6) and put it into the Motherboards 2x8

I have the feeling that your terminology is off.
"2x6" means 2 rows of 6 pins (12 pins total).
A PCIe power connector is either 2x3 (6 pin) or 2x4 (8 pin).

dohh... you're right lol. so to revise my question
could a 2x3 pin be used in the 2x4 pin?

No, the PCI-E power plugs, and the ATX12V/EPS12V connectors are NOT interchangable. You might smoke something.

You can plug an ATX12V 2x2 (4-pin square) connector, into half of an EPS12V 2x4 (8-pin rectangle) connector. That will work, it's designed to.

That's if your PSU only has the 4-pin ATX12V mobo connector, and lacks the EPS12V 8-pin connector, but your mobo has an EPS12V 8-pin socket.

yep. the other 4 pins are supposedly for power stability if you OC a lot, but its optional

Now you know why I questioned your "2 x 8."

You definitely do NOT want to connect one of the Pci-e connectors to that socket...you'll damage the motherboard, and possibly the power supply and even CPU.
If your power supply doesn't have even a 2x2 (4 pin) connector, you CAN buy adapters that connect to one of the 12v molex-type connectors...but most power supplies built in the past several years have at least a 2x2 pin connector. Those are acceptable...IF you don't overclock your CPU...or at least, if you don't heavily overclock...ymmv depending on psu.
