Does this need to be connected?

    I was always under the impression that it isn't needed but can help send extra power to the GPUs and was especially helpful in multigpu builds or a heavily overclocked scenerio.
     
    p.s.  I plugged mine in on the z590 dark with a single 3090 kingpin.

    Supplemental PCIe 6-pin Power Connector:
    The 6-pin PCIe connector at the bottom of the motherboard provides dedicated power to the PCIe x16 slots, augmenting the +12V power provided by the 24-pin and power directly to the GPU (See Page 43 for more specifics to the connector itself, and associated wiring/pinouts). This connector is optional for a single card solution, but is recommended for SLI, CFX, and dual-processor video cards.

    The z590 FTW has a 4pin supplemental CPU connector at the top of the board. This connector is not required for normal operation, but is available to provide more power to the CPU if a user is doing a more exotic cooling benchmark. For normal air and watercooling operation, it is not required.

    The z590 Dark board has an 8 pin CPU supplemental and a 6 pin PCI supplemental, which rblaes is referring too.

    From the manual for the FTW, since that is the board in question (please specify exactly which product in the future):

    z590 FTW Manual

    Page 41 of the user manual
    ATX 4-Pin 12V Power (PWR 4P) (Optional)
    ATX PWR 4P (OPTIONAL), the 4-pin ATX 12V power connection(s), is used to provide additional power to the CPU. Some power supplies provide a dedicated 4-pin CPU ATX power connector, while other power supplies split an 8pin EPS connector into a 4+4 pin connector; either of these 4-pin power connector are proper connectors for this port.
    This secondary power connector is optional to provide additional power for improved overclocking. Please remember to make sure that the tab on the ATX socket is aligned with the release clip on the cable. NOTE: If the tab and release clip are on opposite sides, powering on the system WILL damage the board. Please review installation instructions from your power supply manufacturer to verify which connectors may be used for the CPU power.

    The extra CPU power connector does not need to be used for ambient overclocking, it will work fine without it if you do not have a cable to populate it with.

    I would use it. There is no reason not to other than cable management.
