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. Review: Perfect - 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. ## Features - TYPE-C Port Small Board Card 3TK78AA Compatible with HP 400 600 800 G4 DM SFF MT. - Compatible P/N: For 3TK78AA - Compatible models: For HP 400 G4 DM SFF MT; For HP 600 G4 DM SFF MT; For HP 705 G4 DM SFF MT; For HP 800 G4 DM SFF TWR - Warranty: 6 months. - You will receive: 1 x Type-C CARD board. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BWDSXXS2 | | Best Sellers Rank | #1,893 in Laptop Computer Replacement Parts | | Brand | BestParts | | Compatible Devices | HP 400 G4 DM SFF MT, HP 600 G4 DM SFF MT, HP 705 G4 DM SFF MT, HP 800 G4 DM SFF TWR | | Customer Reviews | 4.4 out of 5 stars 29 Reviews | | Hardware Interface | USB Type C | | Item Weight | 0.02 Kilograms | | Manufacturer | BestParts | | Mfr Part Number | XA.SW.115-F1 | | Model Number | XA.SW.115-F1 | | Operating System | Windows, Linux | | Style | Classic | | Style Name | Classic | ## Product Details - **Brand:** BestParts - **Compatible Devices:** HP 400 G4 DM SFF MT, HP 600 G4 DM SFF MT, HP 705 G4 DM SFF MT, HP 800 G4 DM SFF TWR - **Hardware Interface:** USB Type C - **Item Weight:** 0.02 Kilograms - **Style:** Classic ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/71E1I1AxdnL.jpg) ![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 - Image 2](https://m.media-amazon.com/images/I/71JRCoeAdAL.jpg) ![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 - Image 3](https://m.media-amazon.com/images/I/61c32chAk3L.jpg) ![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 - Image 4](https://m.media-amazon.com/images/I/61TVHU4CmNL.jpg) ![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 - Image 5](https://m.media-amazon.com/images/I/61mZMyMmWgL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple Set Up, Works As Advertised. *by A***G on June 3, 2025* Works great in an Elitedesk G4 and an HP Prodesk 600 G3.
