Verify that your motherboard uses a 20+4 pin ATX connector and a 12V ATX power connector as listed. Confirm the system requires one SATA power lead two large peripheral leads at 15 inches and two at 6 inches plus one 6 inch small peripheral lead. Ensure the 110V 220V switchable input matches your local mains voltage.
