Review: Works great! Sadly I won't need it anymore - 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
Review: Simple Set Up, Works As Advertised. - 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.

### ⭐⭐⭐⭐⭐ Perfect
*by J***R on February 6, 2025*

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.
