If 240VA limiting is not a requirement for the power supply than all +12V outputs are common and may have the same wire
color (yellow).
6.1.2 +12V4 Baseboard Power Connector
STATUS
Required for 700W, 750W and 800W power levels
Systems that require more then 16A of +12V current to the baseboard will require this additional 2x2 power
connector. This is due to the limited +12V capability of the 2x12 baseboard power connector. +12V4 will power
this 2x2 connector.
