4 pin cpu socket asrock z 68 pro3

[johnthesmilers]

hi all,,,
currently i have amacrox free earth 88+ 500 w and asrock z68 pro 3
http://www.amacrox.com/english/01_product/02_01detail.aspx?pdid=54

now, the asrock has 8pin cpu socket...while my psu have only 4x2 pin...
and the cable can't reach the socket....
so now i bought the nzxt sleeve extension cable...

what i am asking is :
do i have put the 4x2 pin to 8 pin cable or do i just need 4 pin to 8 pin..
is there any differences in that

sorry if my question is too basic since im new to this...

Read the manual!

Though this motherboard provides 8-pin ATX 12V power connector, it can still work
if you adopt a traditional 4-pin ATX 12V power supply. To use the 4-pin ATX power
supply, please plug your power supply along with Pin 1 and Pin 5.
