Based on the problem description, I recommend you doing the following:
- If possible test another compatibility with the processor.
- Test if possible a different power supply.
- Change if possible the power cables.
In the case that you have tried these troubleshooting steps, I recommend you contacting your Intel® local support so they can help you out with the RMA for the unit.
