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.

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

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.

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.

Prevented computer from booting up. Useless.

It is great and useful and works with elitedesk 800 g5 well. I have usb c display port on it with no problem.

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!)

Works perfectly.
