Hi, looking for something efficient to power this board with besides an over-spec'd inefficient PC PSU, and I'm wondering if the 3.3v rail from the ATX connector is actually used at all or if this board regulates its own 3.3v from the 5v or 12v rails? I see Mean Well have a nicely sized psu that provides 12v and 5v that should be suitable provided the board is regulating its own 3.3v. Thanks

hi just wondering can i use this one
Seasonic SSP-300SUG Active PFC, 300W Flex/Mini 1U, Intel Haswell ready, Japanese capacitor, Operating temperature 0-50°C, 80+ Gold, Modular wire
+3.3V@10A, +5V@14A, +12V@25A, -12V@0.3A, +5VSB@2A
We do use the +3.3v rail specifically, which is why we ran into issues with PSUs that do not have a reliable +3.3v rail (see the Interceptor FAQ for more information). We also use the +5v and +12v rails where applicable.
