I believe the power traces are different, so the CPU VRM feeds only through the EPS12V connector. However, if your PicoPSU is large enough, I guess a EPS12V cable can be attached to it.
Probably not for a 35W CPU
In comparison I have various other boards with higher wattage CPU's that lack EPS connectors such as an AM1 for a 40W CPU...what is different? I mean the 8pin one not the 4pin cpu cable.
but generally: Using adapters for the EPS12V connector is dangerous.
I know - I am the one who added that on the wiki :D but it is always good to repeat it :D
They have more than two pins for a simple reason: The electrical current through each pin/connection must not get too high. There are adapters that route the whole current through a single pin on the other end (e.g. a single old-school PATA drive connector).
Oh man that is bad
I wanted to either not connect a 8pin cable at all since a very similar platform on the AM1 series doesn't need or come with one or use one of my adapters that combines a 4PIN CPU cable and a molex cable which has worked fine on my H8SCM with the same CPU before I got a new PSU for it (H8SCM only $40 - I don't want to risk this $300 brand new KCMA-D8 although they are going for only $90 china used on fleabay atm)
Never use these unless you know they can take the current you expect! (e.g. not much more than 3A for a 35W TDP, that might be ok for a single pin, but you should read each connectors specs)
Same applies to the tiny connectors for (hard)-drives on the PicoPSU, if the current goes through less pins on the PicoPSU side, don't do it (unless you know what you are doing).
I always check the ratings.
There are PicoPSUs that have a 4-pin EPS12V connector btw.
I know I have one :D
But dont I still need 8 pins total?
So I'm not sure what the original question was; would it work w/o full 8 pins?
I just want to make it work with a normal CPU 4pin cable
or would it work w/o any? The former likely yes, the latter likely no.
