Hmm strange question but you cant really get it wrong you plug the 20 pin conector from the power supply into the board then plug the little 4pin block which is on a diffrent cable into the little 4 pin block on the motherboard there all shaped to fit the conections so you cant get them wrong

Hello Ahmed, All Cpu comes with power supply in a form of a metal box about 4" x 4" x 3" with alot of wires in a bunch or in pairs. Plug in the black/white cable at the back of the Cpu socket and then to the house supply and switch on. Thats it!
