I have a problem :(

I want to buy a 600w PSU but i have a 24pin and a P4 conector (4pin atx 12v or whatever ther are called) and i can't find a PSU with  4 pin connector i have gigabyte GA-H61M-S2PV motherboard.  

most psu's have them. 

Yes most of the time the CPU power plug (now usually 8 pins) will split into two 4 pin connectors. You just use the one. 

This a decent one that is semi modular ... but it depends on what country you are buying in.
