Compatibility Gateway SX2851-41 PC with USB 3.0 Two-Port Expansion Card

I would like to upgrade my Gateway SX2851-41 PC with USB 3.0 Two-Port Expansion Card.

  1. Does it require additional power connection?
  2. Do you have PC compatibility list?

Hi Oleg,

Thanks for posting! I’ll be happy to help. According the the spec sheet here:…

Your machine does have the required PCI-e X1 slot it looks like it isn’t available. If your PCI-e X1 slot is available, it should be compatible. The card actually runs fine when powered only from the PCI bus. Also, be aware that there is no support on Mac.

Unfortunately we do not have a list of all compatible machines. We do offer a 30 day money back guarantee if it doesn’t work out for any reason.

I hope this helps, let me know if there’s anything else I can do to help.

Happy Holidays,

Hello, Jerome,

Thank you for your kind response. My PC has free PCIe 1x slot but it has no free power connectors. I worry because I already have unpleasant experience with BYTECC BT-PEU310 USB-3 card. It did not work with my PC at all. I have ordered your card. Hope everything is fine.

Best regards,


Just received the card. It works with no problems.

Hi Oleg,

Thanks for letting me know! I’m glad to hear you are up and running.
