Oh that is good to know!
How else am I supposed to power the riser if not with the included sata adapter. (I would have plugged it into the PSU originally.) I'm pretty sure the riser I bought said it is intended for use with a GPU.
My (pretty stupid) project is to use a NUC with a GPU, but I want to fit it into a Wii case.
Next to NUC, GPU, cables and 1 or 2 tiny fans, there is not much room left.
The plan I have right now is to plug a dell 330w external power brick into the case and split it internally to the NUC and (over the HDPlex PSU) to the GPU.
I want to avoid making the Wii look too different from the outside and I would also like to not have 2 power cables plugged into it.
Thank you very much for the help!
I would feel more comfortable cutting the Sata connector and solder or crimp the cables directly to the power supply.
Most NUCs and other mini PCs also run fine on 12V (despite they come with a 19V brick). I would try that first because it simplifies the setup a lot. If your NUC runs fine on 12v you don't need the HDplex but just a 12V brick (e.g. Dell) and a load switch for the GPU like my GxR-DIY. You can check my thread below. There are some similar builds like what you are planning:
Completed - GxR-DIY Edition - a tiny 12V 600W load switch module - works with NUC, Deskmini, Pico-PSUs and more
Some of you have probably seen how Josh | NFC 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...
