Hi,
I have
Corsair HX1200i. Currently I want to connect
two Sapphire Nitro+ Radeon RX 580.
As per the PSU manual:<start>2.7 Installing the 4-pin Power ConnectorsThe two extra 4-pin power connectors on this motherboard offer more power for
your graphics cards. They provide stable voltages and greatly reduce the risks of
burning your motherboard 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 (1) to the 4-pin
power connector closer to the PCIe x16 slot (A PCIE_PWR1) .
Then plug another PSU's 4-pin power connector (2) to the other 4-pin power
connector (B 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: Make sure both the connected 4-pin and 24-pin power connectors are on the
same PSU; otherwise, the motherboard may be damaged.
<end>Question No. 1: Do I need to install the 4-pin connectors from PSU to the motherboard?I will use risers and
understand that I have to power the GPUs directly from the PSU.Question No. 2: Do I need to install the 4-pin connectors from PSU to the motherboard in case I increase the GPUs?Looking forward for your response.
Thanking you in anticipation.
Regards,
Rizwan
