Apple G5 dual 2.5ghz

I need to see the inside photo schematics of the airport connector and the 3 small cables that connect to the motherboard, the airport card, and who-knows-what-else.  I need to plug them all back in after installing an airport extreme card.  Any ideas?

Hi I bought apple I mac G5 1.6mhz 80gb serial number W84457TKPP6 from eBay. I'm just wondering how I connect it to internet? Do I need dongle and if yes what do I buy? Thank you. Regards Alison.

apparently you can use a wi fi usb adapter

But suggest checking if the g5 has a wireless card installed in it first before buying a dongle.

you may have an airport extreme card but if it does not have one see link below

suggest asking an apple store for advice on the g5 Imac

this help link should show where the card should be installed in your G5

The Acer Aspire E500 Desktop PC uses an Acer MBP2207024 motherboard,

I'll be referring back to the photos of the motherboard, at the bottom of the page of the above link.

Start with the power cables coming from the Power Supply, to the motherboard.

1) 24-pin ATX main power cable, and corresponding connector on motherboard:

Middle and bottom photo. Look at the top left side. There is a whitish long connector, with 24 socket holes in it, on the motherboard.

Here is an average example of the power cable, and the connector on the motherboard,

[Note* Color of connectors does Not matter ]

2) 4-pin ATX +12 Volt power cable:

It's hard to see in the photos. Go to the bottom photo.
From the left side; look at the purple Keyboard port, and green Mouse port.
Go to the right to the blue VGA port. (15 socket holes. 3 rows of 5)

Now go to the stack of 3 ports to the right of the blue VGA port.
Two USB, then a Firewire port on top. Right behind this stack, is the square 4-socket hole, whitish 4-pin ATX +12 Volt connector.

Average example of motherboard connector, and corresponding power cable,

Note that on the male power cable connector, for the 24-pin power cable, and the 4-pin power cable, there is a Lock.
Shown more visibly in the middle photo of the above link.

This Lock acts like a see-saw on a playground. The top is squeezed in, and this action releases the hook at the bottom end, away from the tab on the female motherboard connector.

To ensure that these power cables are plugged in tight, the Lock needs to be in the lock position, over the tab on the female motherboard connector.

This power cable is power for the Processor.

That's it for the motherboard.
There should also be a SATA power cable coming from the Power Supply, to the SATA harddrive.

Average example of a SATA power cable,

There are two cables going to a SATA harddrive. The SATA power cable has the longer connector. It has 15 pins. Note that there is also an L shape on the inside of the connector. Lines up with the L shape on the harddrive.

The other cable is a Data cable. (information cable)
It has 7 pins, and is the shorter of the two.
Average example of a SATA data cable, and corresponding connectors on a motherboard,

Look at the photos to the top/right. The top photo shows an average SATA data cable. (Color does Not matter)

The photo also shows a Straight connector. This style of connector is usually used to plug into the motherboard. (Sometimes for SATA optical drives, also)

An Elbow shaped connector is usually used on the Harddrive side.


This is a 4-pin standard Peripheral power cable,

Shown connected to an older IDE (PATA) harddrive. It is also used on optical drives, and to computer case fans sometimes.

IF, your SATA harddrive has a provision on the back for a SATA power cable, AND a 4-pin standard Peripheral power cable, ONLY use just the SATA power cable.

Otherwise the SATA harddrive will BURN up.
May not happen immediately, but I assure you it will happen.

In the middle and bottom photos on the Ascendtech link, the SATA headers (Connectors) on the motherboard, are Orange, and at the Top/Right.
There are 4 of them.

The beauty of SATA:
Next to the SATA headers on the motherboard will be silkscreened a figure. SATA0, SATA1, SATA2, and SATA3.

Or it may have SATA1, SATA2, SATA3, and SATA4.

A harddrive should plug into SATA0, or SATA1.
HOWEVER, the beauty of SATA, is that you can plug the harddrive into ANY of the four SATA connectors on the motherboard, and BIOS will find it.

The plastic front of your computer is the Front Panel.

The rectangular block of plastic with pins sticking up out of it, on the motherboard, that the wires from the Front Panel go to, is the Front Panel header.

Sometimes abbreviated as F_PANEL, or FP1, or PANEL_1.

Looking at the Top motherboard photo, it is the blue rectangular connector, at the Bottom corner.
In the Bottom motherboard photo, it is all the way to the Bottom/Right corner.

(Middle photo all the way to the right corner)

The CPU Fan, (Central Processing Unit, or also known as Microprocessor, or Processor for short), cable connects to the small 3-pin whitish connector, that is towards the top of the motherboard, and above the 24-pin ATX main power cable connector.

The System Fan, (SYS_FAN), or computer case fan, connects to the small 3-pin connector to the Right, of the 4-pin ATX +12 Volt connector, on the motherboard.

Front Panel header pinout to follow in a Comment.

Recently changed the power supply. There is no video output. Where can I download the motherboard schematic?

Right here at HP Support,

1) Motherboard Specifications:

Scroll the page down to the top view illustration, and photo.

A) The motherboard uses a 24-pin ATX main power cable.
In the illustration the connector on the motherboard is on the right side.
It is an empty rectangular box with ATX Power Connector in it.

On the motherboard photo it is the rectangular white connector with two rows of 10 socket holes, and is to the bottom right of ram memory slot 2.

Another example of a 24-pin ATX main power cable,

Ensure that the 24-pin ATX main power cable's connector, is locked into place on the motherboard's connector. The lock tab on the main power cable must be hooked over the tab on the motherboard connector. This ensures that the main power cable is in all the way.

B) The motherboard uses a 4-pin ATX +12 Volt power cable.
The connector on the motherboard is a white square connector, with 4 socket holes.

In the illustration it is to the bottom left corner of the Processor socket (LGA 775), and has ATX12V underneath it. This power cable's connector also has a lock tab.
Another example of a 4-pin ATX +12 Volt power cable,

Power TO the motherboard, that's it.

Power FROM the motherboard:

C) System Fan, and CPU (Processor) Fan.

Abbreviated as SYS_FAN, and CPU_FAN to the bottom left of the ATX12V connector.
(4-pin ATX +12 Volt connector on the motherboard)

The System Fan is the computer case fan.
CPU Fan is the Processor fan.

D) The four SATA headers on the bottom right in the photo, (Blue, Orange, Black, and White), are for the SATA data cables.
They connect to a SATA harddrive, or SATA optical drive. (CD/DVD drive)
(They are an L shaped connector inside, with 7 pins inside)

Power for these SATA devices comes from the Power Supply.
The Power Supply has SATA power cables.
Example of an average SATA power cable,

(L shaped connector with 15 pins inside. The longer connector between a SATA data cable, and a SATA power cable )

Did you forget which SATA data cable plugs into where, on the motherboard?
Don't sweat it.

The beauty of SATA is that you can plug the harddrive's SATA data cable into ANY of the SATA headers (Connectors) on the motherboard, and BIOS will find it.
Same with a SATA optical drive, or any SATA device, for that matter.

IF, your SATA harddrive has a place on the back for BOTH, a SATA power cable, and a 4-pin standard Peripheral power cable, ONLY use the SATA power cable.

Using both will eventually burn out the SATA harddrive!

Example of a 4-pin standard Peripheral power cable, (Misnomered as 'Molex'),

From there the main optical drive, (CD/DVD drive), has to have the audio cable plugged into the audio connector on the motherboard.
(Plus the power cable, and data cable, of course)

In the illustration this is the header down in the very far left corner, and located towards the bottom edge.
It has CD_IN marked underneath it.

In the photo it is the Black rectangular connector in the very far left corner.

If you didn't connect the 4-pin +12 Volt power cable, your Processor isn't getting any power.
No Processor operating, No computer.

No Signal on monitor.
(No video signal)

How to install an internal hard drive (1.5 tb) on a ppc g5

there are actually extra spaces for internal drives with the proper connectors for the ribbon cable and the power cable.
Just open the side of the G5, and double check your connectors prior to purchase to be sure you get the proper type. You can connect it to the available connectors on the existing ribbon and power cable... Then boot it up and simply do a disk utilities mount and format of your drive and you're good to go.

Airport Extreme 802.11g

At this point you are much better off installing a USB wireless antennae than spending money on an Airport card, cracking open the iMac, and installing it.

USB wireless adapters are cheap, plentiful, and have more capabilities than the generation of Airport cards that were made for G5 iMacs.
