Note:
+12V current to PCIe slots may be supplied from four different connectors. 12V1 on P2, 12V2 on P3, 12V3 on
P1, and 12V3 on P12. P12 is reserved for board that needs 4 x GPU cards powered. P1 is the main 12V power
for PCIe slot; but additional 12V power can be connected to P2 and/or P3. The motherboard MUST NOT short
any of the 12V rails or connectors together.
