Do you guys know if this works with the ASUS PRIME Z270-A?

I received the adapter and now I’m configuring/testing it with a 7th gpu. When I get a stable configuration ready I’ll publish it

Have you tested it with these motherboards yet? ”
BIOSTAR TB250-BTC PRO, and BIOSTAR TB250-BTC , ASRock H110 Pro BTC+, or ASRock H81 PRO BTC R2.0 ? I have rigs running on all these motherboards. I’d be happy to test them all and report my findings. Could you send me a sample to try out on these?

It has been confirmed to work with the first three motherboards you mentioned. I do see that you currently have a pending order and we will include one of these expansion kits with that order once it is paid for.

  1. 5 out of 5


    This PCI-E 1X 1 to 3 Ports expansion kit works perfectly and is ready to use out of the box. No drivers needed.

    Before buying be sure to have a motherboard with “above 4G decoding” option and enable it on the bios/uefi. This options is standard on LGA 1151 motherboards. If you have an Asrock Pro BTC R2 LGA1150, you can also use this adapter but first, install the latest bios (beta at the moment) from Asrock website to get the “above 4G decoding” capability.

    Steps to install the expansion kit:
    1) Turn off your power supply.
    2) Insert the card with the PCI-E 1X male connector into the last slot on your motherboard. If it doesn’t work in this slot, try another one.
    3) Connect a sata or molex (just one) power connector to the adapter card with the 3 female PCI-E 1X ports. This is required to give power to the chip on the card. Remember this is not just a riser with multiple ports.
    4) Use the USB 3.0 cable to link the riser card connected in the motherboard and the adapter card with the 3 PCI-E 1X ports.
    5) Enter your bios/uefi and enable the “above 4G decoding option”, usually located on the chipset section.
    6) Is recommended to set the PCI-E 2 link speed to gen1 if is not already selected. This option is used for some motherboards even for their own native ports.

    Be sure all your risers are working perfectly. You can get false positives on the adapter because of them.

    At the moment, I just tested using 2 ports on the adapter (7 gpus in total). As I have understood, for Asrock Pro BTC R2 LGA1150, the maximum allowed cards to be recognized is 7 but maybe with the new beta bios, there is more room for additional cards.

    For LGA1151 newest motherboards, you can use the three ports on the adapter. In theory, is even possible to use multiple adapters on the same motherboard.
