I'm planning on running a 1080ti off of a 250w AC to DC power supply while the rest of the PC is on another supply, hence the need for a load switch.Hi @JarrettP, yes I have only one for sale, currently wired with two 18AWG input wires and two 18AWG output wires.
There is room for more wires if you do not mind soldering on PCB pads.
May I ask what kind of setup you have in mind ?
Here is the beast :
Or a flexible m.2 to PCIe-4x + powered riser
I'm planning on running a 1080ti off of a 250w AC to DC power supply while the rest of the PC is on another supply, hence the need for a load switch.
My goal is to stuff an 8700k, Zotac 1080ti mini, and their power supplies into a Skyreach Mini. I still haven't figured out the exact PSU placement since I'll have to use 2 AC to DC supplies plus a G-Unique for the mobo, but It looks like it should work.
This build is gonna be quite a bit more involved than an external brick build, so some light soldering is the least of my concerns.
The EPP-400-12 itself actually won't fit in the S4 with a graphics card installed. It's a 3x5 power supply. Only 2x4 power supplies will fit.I had this load switch designed for this very purpose Price is 30 € excl. shipping, which should cost around 10€.
To help with your design, PCB Size will be 17.02x27.03 mm (with heatshrink and cables probably around 2x4cm).
Fitting two of these units in a S4 seems quite difficult to me : they're not that small and need around 20 CFM of airflow under load.
Why not going for an external brick and an internal EPP-400-12 ?
BTW, I am aiming at exactly the same setup dual GTX 1070 powered by an EPP-400-12, rest of the system powered by an EPP-300-12.
Actually, I hadn't seen that Acbel 275w. That's a really interesting form factor. I don't think it would work with my build, but regardless it's interesting.I happen to have the 250W Artesyn CPS253-M ; it's so tiny compared to the EPP-300-12, which provides only 45W more !
It costs twice the price though...
I guess you already saw it, but Acbel (EOS Power in Europe) also makes a very thin 5 x 3" unit 275W, only 19 mm high.
You can indeed try to fit two 2 x 4" open-frame PSUs in a S4 but I would be a bit worried by temperatures, especially the 1080 Mini.
You still have the option to power your system with a 12V 192W AC Adapter from Mini-Box and your GPU with an open-frame PSU.

2% ripple and noise. ATX specs is 1%. You would need additional regulation.
I'm sure it is usable but I'd be a bit worried about longevity of the motherboard
@Thehack : according to the Artesyn CPS250-M documentation, only the Line and Neutral wires are connected to the input connector.
The Earth wire is to be crimped with a ring terminal and attached to the chassis or the PSU PCB, right ?
Regarding that ring terminal, is it "better" to place it over the PCB or under it (between PCB and spacer) ?
