BestParts Type-C USB 3.1 Gen2 Port Flex IO Card Small Board Replacement for HP 400 600 705 800 G4 DM MINI SFF MT 3TK78AA

Works great in an Elitedesk G4 and an HP Prodesk 600 G3. Install was simple. Using it with a Yottamaster 5-Bay DAS with USB-C 3.1 Gen 2; speeds are really good especially since I am always transferring large amounts of data to/from my HDD's and SSD's. I can send data to 4 drives at the same time and maintain 230-250Mb/s on each. One thing to note if this get stuck at boot, a new option shows up in BIOS, I forget the location but there will be a new checkbox for USB-C firmware update for that flex I/O port. Disable it. Been using this for a while now with no issues.

Item was new or like new, well packaged in ESD bag. Came with screws to secure it to the motherboard. Worked great on the HP ProDesk G4 600 SFF computer. I was able to use a USB C monitor with the desktop now, as video would not pass through the front built in port. After replacing the VGA module with this, it worked no problem. You may have to check the bios settings, so don’t despair right away if it doesn’t work right away. Also make sure it is seated properly and that it is secured properly. I had no issues with either and it worked first time.

I replaced the VGA Flex IO Card with this USB C Flex IO Card and it works like a plug-and-play device on my HP ProDesk 400 G5 SFF. There is no need for drivers or any other configuration. I did have the latest BIOS firmware installed to avoid any potential incompatibility issues. The Amazon listing does not state that it is compatible with this computer model, but it is.

It took two times to get a working board. Once installed , it worked perfectly.

Defective...Computer boots fine without it but when installed Front LED stays on and computer will boot and post for 3-4 seconds then all power is lost HP Elite Desk mini 800 G4 Remove the card then all word fine tryed reseting bios while card was in it nothing ... ether DOA or not compatible...
