Hello there,
I will propose in the near future two 12V builds accessories, which are merely continuing Qinx work on H2o Micro.
1. +12V Load Switch :
This load switch is intended for everyone powering their GPUs with an open-frame 12V PSU, such as the notorious Meanwell EPP series.
2. Thin Mini-ITX powered riser
We are aiming at producing a powered riser that folds over thin mini-itx motherboards, with the abilty to have it powered only by the PSU (+12V from the slot will be cut).
The riser will be synced with the system, which means that NO +12V will be fed to your GPU while the system is OFF.
Update #1 : Design
Update #2 : Prototype
Update #3 : Production

1. +12V Load Switch :
This load switch is intended for everyone powering their GPUs with an open-frame 12V PSU, such as the notorious Meanwell EPP series.
For me, the only drawback of that compact solution is that the GPU is constantly fed with +12V, even when the system is shut down.
To cut the +12V current when the system is off, I proposed to a more knowledgeable member of [H] to develop a small +12 load switch.
It is based on a Mosfet and soldered wires to achieve the smallest footprint possible : 17.02x27.03 mm.
Principle : the circuit is hooked up to a fan header from the motherboard which triggers the MOSFET and closes the circuit.
I already have three of these babies, which work perfectly !
One will be used in my dual-GPU setup, the other one in my thin mini-ITX computer.
If you are interested, please let me know and we'll run an other batch.
The PCB with the components soldered should cost around 15€ excl. shipping.

The riser will be synced with the system, which means that NO +12V will be fed to your GPU while the system is OFF.
You may remember the custom PCIe 4X to 16X powered riser that Qinx developed some times ago.
Just for reminder : the +12V trace of the riser has been cut so that all the +12V slot power the GPU needs is provided by the 12V PSU.
I'm currently running one succesfully in my thin Mini-ITX build.
However, to improve Qinx work, the next logical step is to integrate the load switch previously introduced into the PCIe 4X riser !
The principle would be the following : the MOSFET would be triggered by the +12V coming from the slot.
Currently, we are aiming at producing 5 units, which should cost around 50€ each fully soldered.
Following the demand, we may produce more and get lower prices.
Please let me know as we are going to start the development soon enough.
