    Unhappy amibios detected only 4-pin connector connected for the CPU issues

    Hi,
    I recently purchased a ROG STRIX X570-E GAMING WIFI II motherboard, I used my rig without any problems during 3 weeks
    but suddenly the amibios start to say "the system has only detected a single 4-pin connector connected for the cpu".
    I can boot but no internet, no sata access, access to my nvme main windows 11 partition only.
    I checked the cables, changed the cables but always the same message, I need my computer for working so I reinstall the
    ancient motherboard and have no problems.

    my config :
    ROG STRIX X570-E GAMING WIFI II motherboard
    x5900 amd cpu
    corsair vengeance LPX 32Gb x 4 sticks
    msi RTX 2070 super
    corsair HX1000 PSU (I also check with another PSU and same problem occurred)
    windows 11 pro 64bit

    the latest BIOS installed,
    I updated to the more recent AMD chipset drivers before the problem occurred
    I tried to reset CMOS, I change CMOS battery too, same problem...

    please help me

    Connect both E-ATX as recommended

    Set DOCP profile for your RAM

    Procedure for install of windows on a new NVMe drive.

    Enter BIOS, Advanced mode,

    1 - Make sure you unplug all SATA and USB drives, the M.2 drive has to be the only drive installed.
    2 - Go into the bios, under the boot tab there is an option for CSM, make sure it is disabled.
    3 - Click on secure boot option below and make sure it is set to other OS, Not windows UEFI.
    4 - Click on key management and clear secure boot keys.
    5 - Insert a USB memory stick with a UEFI bootable iso of Windows 10 on it.
    6 - Press F10 to save, exit and reboot.
    7 - Windows will now start installing to your NVME drive as it has its own NVME driver built in.
    8 - When the PC reboots hit F2 to go back into the BIOS, you will see under boot priority that windows boot manager now lists your NVME drive.
    9 - Click on secure boot again but now set it to Windows UEFI mode.
    10 - Click on key management and install default secure boot keys
    11 - Press F10 to save and exit and windows will finish the install.

    Hope you find this helpful.

    At a guess, you may have corrupted the installation of windows. You have near to top-of-line CPU and bottleneck for power being supplied to the motherboard.

    It may be more than that, re set in your 8 pins connector and make sure the connector on both end of PSU and CPU are sit correctly and the rail not the issue.

    Unhappy

    hi,
    I tested with another PSU and I obtained the same error message,
    followed @RedSector73 procedures and reinstalled windows on a new nvme, stuck during installation because
    ethernet and wifi are out of service, I bypassed with OOBE\BYPASSNRO command
    finally reinstalled, installed asus drivers with CD-rom but nothing changed at all.
    No SATA, no wifi, no ethernet, cannot use some of the motherboard USB ports too.
    for me it's sound like a faulty material issues but I'm not a pro.

    Hi, thank you for the reply, I check the cables, tried with other cables and another PSU
    same problem. Windows fresh install on a new NVME disk changed nothing too.
    I also tried other memory sticks, nothing changed.
