Verify that your chassis and power supply is appropriate for the processor model and frequency and the desktop board you have.

An ATX12V or SFX12V with the 2x2 connector is required for all Pentium® 4 processor-based and higher Intel® Desktop Boards. Power consumption requirements for high-end video cards, sound cards, peripherals, and the Pentium 4 processor will exceed the typical 5A current capacity of standard ATX & SPX power supplies.


⦁    Do not use 2x2 power cable adapters with non-compatible older power supplies.

⦁    Verify that the power supply has the capacity to power all the devices used in your system.

⦁    Ensure the power cord is firmly connected to the power supply and the AC outlet.

⦁    If the power supply or the AC outlet has an on/off switch, make sure that it is on.

⦁    Determine power supply voltage selector setting (230 volts vs. 115 volts) is correct.

⦁    Check for foreign objects inside the chassis such as screws that may ground the desktop.

⦁    Attach the desktop board correctly to the chassis base with the spacers/stand- offs. Make sure not to tighten the screws too much.

⦁    If possible, use a voltmeter to verify that each output from the power supply is correct. If any output is very low (especially the +5 volt output), consider replacing the power supply.

⦁    If possible, use a voltmeter to verify the PowerGood signal is +5 volts. If the signal is below 1.0 volts, there may be a short or overload causing a constant reset. Consider replacing the power supply.
