4 pin ATX Power Connectors for my new build

Hi,

I just built a new PC with the following configuration:
Processor: Intel Pentium G630 Sandy bridge
Motherboard: Asus P8B75-V
Graphics card: Sapphire Radeon HD7750
RAM: 12 GB
HDD: 1 TB Western Digital Green Caviar
Optical Drive: Asus 24X DVDRW
PSU: 450W iball

My motherboard has a 8 pin ATX power connector as shown in the attachment and my PSU has a 4 pin power connector as attached. As per my motherboard guide it said, i could connect the 4 pin connector from my PSU to one of the four pins out of the 8 pins in my motherboard. I am worried if its going to cause any harm to my system or if i should buy a PSU with an 8 pin connector ONLY. Please advice.

Please note that the pictures are not exactly from my PSU and motherboard. The 4 pin wires from my PSU are two black and two yellow in color.

Change that PSU first thing.... iball ???? Go for Corsair, Seasonic, Antec.

BTW... the picture you posted of the PSU cable.... thats a 20pin+4pin connector which you'll need to combine both of them and put in the mobo power connector which is 24 Pin header. After that you'll need additional two 4 pin connectors or one 8 pin connector to power your CPU... which I doubt the iball PSU has.

AFAI iball 450 PSU has
1 20+4 pin connector (for powering mobo)
4 Sata connectors
1 PCIE 6 pin connector
1 FDD connector
4 big 4 pin IDE power connecotrs

Can you please confirm this ? In any case I strongly recommend changing that PSU.
