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

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.

Was hoping that his would work on HP Prodesk 400 G5 Mini. it does not. It fits but computer would not boot up with it installed. Delivery was fast. Product looked new.

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.

Adding a second USB c port to my mini desktop was very helpful.

Works great. But only AFTER going into the system setup and unchecking "USB Type-C Controller Firmware Update" under Advanced -> Port Options in the F10 menu. This option is enabled by default.If not, it will try to update the firmware on every boot. In my case I got no display after that completed.You might also want to save that to your custom default settings. Especially if you're going to use this for your primary display. (Which works great!)
