Externally connected peripherals, such as SATA drives may require dedicated
power connections from the PSU and are not supplied via the SBC-LX2160A.
PCIe peripherals can be supplied with up to 35 W per slot, 70 W total over both
interfaces. Some PCIe devise may require an additional, external power
connection via the PSU (such as GPUs).
As the board itself consumes not enough power on t
he
ATX
+5V rail, it is recommended to connect an additonal
load, e.g. 3 ½” Harddisk, to the power supply!
Otherwise,
the +3V3 rail may be unstable due to the ATX
speficiation.
