i 5-2400 LGA1155 processor, Gigabyte ga-h55-usb3 mother board, NVIDIA gt 430 video card, g.skill 8gb ddr3-1333 ram, hard drive, cd-rw disk drive, power supply total power 550w rosewill RP550V2-D-SL model# AP-600F12V. I am building this myself, all parts are new except the hard drive, disk drive, power supply, and case. I also got a power adapter to fit the 12v(ATX_12V_2X) because my power supply had two 4v. I checked all power cables same result. Thank again in advance.
If the info you supplied is correct your cpu (SB 1155) is not compatible with your mobo(1156).
You need an 1155 mobo.
