2.8 PCIe Power Connector Installation Guide
The two extra 4-pin power connectors on this motherboard offer more power for your graph-
ics cards. They provide stable voltages and greatly reduce the risks of burning your mother-
board or graphics cards.
When more than three graphics cards are installed, be sure to install the PSU’s 4-pin
power cables to the 4-pin power connectors (PCIE_PWR) on your
motherboard; otherwise, the cards may be damaged.
Please MUST install
TWO
PSU’s 4-pin power cables to your MB’s
TWO
4-pin power
connectors. Plug one of the
PSU's 4-pin power connector (
)
to
the 4-pin power
connector closer to the PCIe x16 slot (
PCIE_PWR1)
.
Then plug another
PSU's 4-pin power connector ( )
to
the other 4-pin power connector (
PCIE_PWR2)
.
If your PSU only provides
ONE
, then please MUST install it to
the 4-pin power connector (PCIE_
PWR1) closer to the PCIe x16 slot
.
Important:
Besides the two PCIe power connectors, please connect the SATA power connector
as well when you install more then three graphics cards. Make sure all the connected power
connectors (4-pin, 24-pin and SATA) are on the same PSU; otherwise, the motherboard may
be damaged.
*The diagrams shown here are for reference only. Please refer to the user manual that comes
with your motherboard for the accurate location of the 4-pin power connectors.
