 Topic: Z390 Extreme 4 Won't Power UpPosted: 13 Jan 2019 at 3:26am |

Hello All,
I'm building a new machine around this Z390 Extreme 4 board. I believe I have everything set up correctly and it will not power up. System Configuration: Z390 Extreme 4 - BIOS Version 1.60 (stamp on MB) Intel Core I5-9600K (9th Gen) Noctura NH-U12S CPU cooler GSkill DDR4-2400 16GB (1 stick in A1 slot) CL15-15-15-35 Samsung 970 EVO NVME M.2 XFX Radeon RX580 ThermalTake ToughPower XT 775W Observations: The pins on the CPU socket do not appear to be damaged. I am using the 8-pin power supply with an 8-pin plug from the PSU. CPU cooling fan is plugged in to the CPU fan connector (# 3 on MB layout) with a 4-pin connector. After turning on power supply it's power LED is lit and MB LEDs are lit red. Pressing power button on case does nothing. Tried connecting both the power switch and reset switch from case to the MB power switch connections and nothing happens. Questions: Is this consistent with MB/CPU compatibility issues I've read about? Will this MB work with just 1 memory stick? Furthur Actions I'm Considering: Getting a cheap 8th Gen Celeron and using it to set and update BIOS Getting dual memory sticks to replace the single one. I should have done this to begin with. Returning the board and getting a different one. |

Is the memory listed in the QVL? If yes it should work. Do any of the fans spin?
Try remove from case and put on cardboard, cpu, board, mem stick \and a speaker What happens? |

Thanks for the quick response RLGL. No fans spin. Basically nothing happens when I press the power button.
Not sure what QVL is. I Wasn't able to find a memory guide on the ASRock site, just CPUS. The GSKILL site said it would work. I have had really good luck with MB over the years (30+). Never had a bad one. Maybe I'm due. I plan on removing the MB, stripping it to basics like you suggested and doing some bench testing. |

Will this MB work with just 1 memory stick? There is no memory of 16Gig. Single of that speed (2400) listed as single slot in the Qualified Vendors List (QVL). https://www.asrock.com/mb/Intel/Z390%20Extreme4/index.asp#Memory |

Test the power supply with the paper clip trick

RLGL I'm pretty sure the power supply is fine. I pulled it from my old system, it has indicator leds that show it's working, and the MB led's light up. I think it may have to do with power going to the CPU. I only had the 8-pin hooked up and it looks like maybe both the 8-pin and 4 pin need to be hooked up for an i5-9600K.

CopyThat I think the single memory stick is an issue but I would think that would show up in POST and not prevent the system from powering up.

Update: I just tested the PS with an old MB pulled from the case I'm using for the new system and the old MB powers up with all status lights on the PS green. So I think the PS is not the issue.
I think my issue is one of the following: 1) Insufficient/No power to CPU 2) Bad MB |

The PS has only one 8 pin power for the CPU so maybe it's not compatible with these newer systems that require 8 pin and 4 pin for CPU

Hey just letting you know - you do NOT need both the 8pin and 4pin headers plugged in. If you have only the 8 pin (like me), it should still work.
I have the Z390 Extreme4 with a 750 Watt Corsair PSU using only the 8pin cpu header and it is working fine with my 9700k. I'd look and make sure your Memory is in the right slot(s). If you read the manual, it tells you to put them in specific slots if you're only using two sticks. If you have something like 4 sticks of memory, try using two or just one and go from there. |
