Hardware Installation
3) ATX4P (PCIe Power Connector)
The power connector provide auxiliary power to the onboard PCI Express x16 slots. When two or more
graphics cards are installed, we recommend that you connect the SATA power cable from the power supply
to the ATX4P connector to ensure system stability.

requires the use of a fan with fan speed control design. For optimum heat dissipation, it is recommended
that a system fan be installed inside the chassis.
