4-pin 12V connector

[badermans]

Do I need to have 4-pin 12V connector to power up my motherboard?

Will it still boot without it?

you could always look at the manual for the board.

i assume your 'DFI NF4 sli-Dr' is what DFI call the 'NF4 SLI INFINITY '

from page 53 of the manual:

Use a power supply that complies with the ATX12V Power Supply
Design Guide Version 1.1. An ATX12V power supply has a standard
24-pin ATX main power connector and a 4-pin +12V power
connector that must be inserted onto CN10 and CN9 connectors
respectively.
The 4-pin +12V power connector enables the delivery of more
+12VDC current to the processor’s Voltage Regulator Module
(VRM).
The 5V/12V power connector is an additional power connector. If
you are using two graphics cards, we recommend that you plug a
power cable from your power supply unit into the 5V/12V power
connector. This will provide more stability to the entire system. The
system board will still work even if the additional power connector is
not connected.

so yes. the 4 pin header is required and an odditional molex connector into the board is also recomended

And don't forget the floppy drive connector!

actually yeah, it is a floppy style connector not a molex it recomends
