For some reason, my load switch seems to have an issue with my G-Unique, at least with that particular motherboard.
I guess I could try a PicoPSU 160-XT instead of the G-Unique but I'm not sure it can handle this build (which needs around 200W at full load with the GPUs ideling).
No room for an SFX PSU unfortunately.
And yes I have a 140mm blowing onto the Meanwell PSU.
I'll have to carefully monitor two of them fittings
Your image isn't showing. Can you fix it or give us a manual link. I'm interested in seeing it.Yes that power supply is similiar to the X7. We had that custom made and payed a whopping 350 USD for two samples. We had those custom made for our prototype case but due to design changes we can't use them anymore. So now we have two Psu's and a pair of Power bricks not in use sitting here
We tried the X7 before and it kinda worked, although we had the last piece of the old version so there was quite the coil whine. So another wasted pair of Powerbricks there, now with a 7.4x5.0 connector ._.
You could say we had some hard luck...
Thats the PSU And these are our power bricksYour image isn't showing. Can you fix it or give us a manual link. I'm interested in seeing it.

Using nfet would require 12V+around 5 V to fully open the transistor. The integrated switch has a charge pump or something to generate that voltage and some protection features and even a current sense(not used). It opens when the input is connected to ground, which i achieve with the additional npn inverting transistor. Thats about it.
GND is always connected. (seperately)
@Thehack : I prefer to use a load switch between the 12V supply and the GPUs, just in case they do not like being powered whern the system is OFF.
Regarding the way the load switch has been designed, let me quote designer :
Regarding my shut down issues (anything using +12V would stay on after shut down), I do not know if it's the G-Unique not turning off properly or the motherboard having the 12 rail connected to the fan, as you suggest.
What I could try is to connect the load switch directly to a G-Unique Molex instead of the motherboard fan header ?
Speaking of 12V open-frame PSUs, what do you think of this one ? Shitty ripple at 12V but good hold-up time :

I can get for 100€ in France.
Anyway, I've chosen to go back to wide-input solutions and @Kmpkt Dynamo Mini would be a no-brainer if it was a tad smaller...
@Link1712 : I had the X7 too, as well as some serious coil whine !
Thanks for your feedback. In such small spaces, the limiting factor is clearly the power source. Any help is appreciated.
Haha, hopefully we wont make an exception ^^My riser and load switch have been designed and build in Germany
Germans have often proven to be pioneers in the SFF quest !
Yes! When @aquelito is inspired his builds are epic.
