Black screen with ATI Radeon FirePro V4800

[DonkeyKongGamer2]

Hi guys,

I have bought a ATI Radeon FirePro V4800, I connected it but the power supply doesn't have a power connector for the GPU (The power supply has a 6-pin, gpu not). The fan works and is also spinning. So as you can see at the picture, do I really need to connect something to it (What is the name of that)? And if yes, how? Or is there a another problem why the screen is black? http://imgur.com/a/XMRyv

My specs:
Motherboard: Asus M2N68-AM PLUS
OS: Windows 8
HDD1: 1 TB
HDD2: 40 GB
CPU: AMD Athlon X2 6000+
GPU: ATI Radeon FirePro V4800

Asus M2N68-AM PLUS has nForce 630a Chipset which is a September, 2007 product.
Supports PCI express 1.1

Motherboard does not have PCI express 2.0 x16, which is a requirement to run the card.

I have check it online and all websites says it has PCI 2.0 x16. Where did you saw it that the motherboard doesn't have it?
