This is a motherboard of an N64 console on the top right of the second pic shows 6 solder blobs which are
1 GRND
Ground
2 Vcc
3.3V 2.7A
3 Vcc
3.3V 2.7A
4 GRND
Ground
5 GRND
Ground
6 Vcc
12V 0,8A

MALE pinout on power plug itself
_____
|123|
|456|
-----

1,4,5 = -
6 = 12V DC 0.8A
2,3 = 3.3V DC 2.7A

FEMALE pinout on console
_____
|123|
|456|
-----

1,2 = 3.3V DC 2.7 A
3,5,6 = -
4 = 12V DC 0.8A
also the 3,3 V pins are interconnected, as are the three negatives,
Does anyone know how I can hook up my adjustable power supply straight to this board to power this.

Like Scott elucidated, it depends on the power supply. If you have dual power supply, you can set one to 3.3VDC, but you need it to supply 2.7+2.7=5.4A, then run two wires from V+, one for first 3.3VDC, one for second 3.3VDC, run one wire from V- to the ground on the connector. Then set the second of the dual power supply to 12VDC and 0.8A, V+ to the 12VDC on the connector, V- to ground on the connector.

If you have tripple power supply, set each for individual voltage and current.
