Some of you have probably seen how [USER=43]Josh | NFC[/USER] hooked up a graphics card to a DeskMini A300 STX board.
Well, unfortunately the DYNAMO 360 used by Josh is currently not available so G-UNIQUE and REVOCCASES have teamed up to work on some alternative for the SFF.NETWORK forum members that works with almost any mini-PC or DC ATX Plugin PSU. All you need is the GxR-DIY and a good 12VDC power supply.
GxR-DIY can be customized according to your needs, just drop me a message.
Example: GXR-DIY complete set for DeskMini & Co.
GXR-DIY PCB only, solder yourself ...
Application example: hooking up a RTX2070 to a NUC (same works for DeskMini & Co.)
we are using the same ADT M.2 to PCIe riser cable Josh was using for his build. Apart from that, we only need a 12VDC power supply and the GxR-DIY module.
first we connect the riser cable and power via the GxR-DIY to the graphics card
second we plug the riser to the M.2 slot of the NUC. Also we connect the "Remote Control" wire from GxR-DIY to any header / PIN on the motherboard which gives us at least +3V once the PC is turned on. This can be for example: fan header, USB header, SATA, etc...
last but not least we plug in our 12VDC power supply to the PC and the modular case-mountable DC input connector of GxG-DIY
after booting up our system we can install the drivers and start to have fun
