And here again with a few questions. My picoPSU came in today and I ordered a Meanwell RPS-200-12-C. I looked at the wiring of the picoPSU and the examples of the first post of this thread and a few questions arose. As mentioned above I will only power a (overclocked) 2400G.
1.
A) Is it better to connect four of the six outlet pins of the meanwell to the mainboard EPS (4/8pin) connector and use the remaining two to power the picoPSU (which only has two input wires anyway).
OR
B) Would it be better to connect four pins of the meanwell to the picoPSU and power the mainboard EPS connector via the picoPSU (seems redundant)?
OR
C) Is it feasible to connect the meanwell and the picoPSU using two wires (of appropriate AWG, e.g. 16) and power the EPS connector via the picoPSU?
2. The cable to connect the picoPSU to the 4/8pin EPS connector has the two 12V+ and the two ground wires bridged, respectively (see image). I have never seen this on normal PSU's. What is the use of it? If I used method A, this wouldn't be necessary, right?

3. More a question out of curiosity, as I won't use the barrel connector. The barrel connector that comes with the picoPSU has only two wires soldered to it. Why are they still using all four pins of the mini-fit junior connector and even bridge these?
Thanks in advance!
