Question about the Onda B250 D8P motherboard.
I got the version that has the PCI power connectors. There are 8 slots but only 6 PCIe power connectors labeled "PWR_PE1", "PWR_PE2", "PWR_PE3", "PWR_PE4", "PWR_PE5", "PWR_PE6". My guess is that they provide power to "PCIEX3, "PCIEX4", "PCIEX5", "PCIEX6", "PCIEX7 and "PCIEX8"? Also guess that slots "PCIEX_16X" and "PCIEX2" get their power from the ATX connector?
Finally, is the 8 pin connector "PWR12" for the CPU?
most likely that is correct pwr12 uses a cpu cable but you must be very carefull as I do not have that one . I have the other version.
measure your 8 pin cpu cable before you plug it in.

not

also if the cable measures like a cpu cable make sure you orient it correctly into the cpu input jack
