Hey how do you connect the power supply in a Chenbro RM22300 Case? Which one of the coloured cords goes to which plug on the psu? Any help would be greatly appreciated. Also this is for an Australian Power Supply, if that makes any difference.

IMHO it doesn't matter if it is an Australian PSU. (Power Supply Unit)

The only thing that would change from country to country, is the AC electricity coming in.

Australia uses 220 Volts at 50 Hertz (Hertz stands for Cycles per Second)
Europe uses 220 Volts at 50 Hertz
USA uses 120 Volts at 60 Hertz
Japan uses 100 Volts at 50 Hertz

The PSU converts the AC electricity into DC electricity.
The DC voltage, and amperage is very small.

Now to the PSU and the Chenbro RM22300

Inside the chassis is a Chassis Management Board.
(It is a PCB
Printed Circuit Board)

Orient your view of the CMB (Chassis Management Board), with the blue dip switch to the bottom.
{Dip Switch is a rectangular blue block with 10 white dip switches }

To the right, and situated towards the bottom are two white Molex connectors.

(Actually they are each a 4-pin standard Peripheral power connector. Molex is a misnomer. It is the first company to produce a plug with this configuration. Sort of like calling an open-end adjustable wrench, a Crescent wrench)

This gives you more information on the 4-pin standard Peripheral power cable,

{The Red wire is 5 Volts DC
The Yellow wire is 12 Volts DC
The two Black wires are Ground wires.

Two D cell flashlight batteries produce 3 Volts DC }

There should be two 4-pin standard Peripheral power cables coming from the PSU.
They plug into the two white connectors mentioned above.

(The shape of the plug, and the connector on the CMB, will only allow the plug to be plugged in, in one direction)

There should also be a Purple cable.

The Purple cable plugs into JP1.

Looking at the CMB as stated above, there are two square looking connectors to the right of the board.
The one at the top is JP1.
(The one under JP1 is JM1)

I would also like you to have the User Manual.
