BestParts 10Gbps Type-C USB 3.1 Gen2 Port Flex IO Card Small Board 3TK78AA

I was working on a cyberdeck that used the HP 800 G4 Mini as it's brain and wanted a clean way to power the USB C monitor I had selected. This was the perfect solution and it worked WONDERFULLY. Everything I tried connected without any issues, or even drivers needed, completely flawless out of the box. It was simple to install with only 3 screws (including the case screw). It has a durable metal backing so you won't damage the board itself when trying to install a USB-C cable. These HP add-in cards are also a LOT more affordable and far more available than the competitors. Unfortunately for me I won't be able to use this board anymore as the last part of my project ended up frying the motherboard on my PC :( Totally unrelated to this product tho, I was just being stupid with my power input

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.

Genuine article works perfectly in a Prodesk 600 G4 Mini. They are not shown in the photo but the package includes the necessary screws, which I was worried about not having. The is so much better than having to goof around with DP and USB cables. Now I have a 1-cable solution for display, keyboard, and mouse.

Exactly what I needed to connect a USB-C monitor to my mini pc.

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.

Prevented computer from booting up. Useless.

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

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!)

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.

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...
