Pin connections on the motherboard of Acer Aspire AX3200-U3600A

I bought a new case and I can't figure out the pin connections from the case to my motherboard to get my PC running again. I'm not sure what the type of motherboard is in my PC. I have everything else connected except the power switch, reset switch, h.d.d led, +p, -p. If you can figure this out I would appreciate it so much. Thanks.

You'll need to know the model of your motherboard, and search for the motherboard manual in the internet if you don't have one.. in the manual search about the power pin connections and you will see where to connect those wires into the pin..TY

Acer aspire m3201 pc power supply unit,output looms connectors have identification markings on them PI/PA/PB/PC/PD/PE/PF/PG .I want to know which componets the Molex type connectors fit. the PC has On

The Molex connectors in a desktop PC are keyed to ensure proper placement. The 4-pin flat connectors that are flat on the bottom and have beveled edged on top are connected to hard drives, CD, and DVD-ROM drives that have matching power sockets. Those devices that have Molex sockets usually have the 40-pin ribbon cables for IDE devices. There will be a four-pin square connector that connects to the socket on the motherboard for the CPU power. Then there is the 20 or 24-pin connector that is the motherboard main power.

Replacing USB ports acer aspire

Ok this gets a little tricky and you should take it to a shop if you are not literate in building PCs. However there should be an AUX USB connection on the motherboards master pin panel. You plug it in the wrong spot you fry the south bridge on the motherboard and its trash. The USB is a powered port.

I bought a new case fan to replace an HP Compaq DC5100 Case Fan. The problem is the fan I bought has a 4-pin molex connector which I didn't find in my computer. Is there a converter from the 4-pi

You will find 3-pin to Molex only as the 4th pin is for control which older Molex does not support. You bought the wrong model fan for your motherboard. You might consider rewiring it with the old connector. See e.g. which provides wiring logic.

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.

I have an aspire M5640 and I upgrade my video card so I had to upgrade PSU to 550W and my sistem frezzes on boot? What can be the problem? Thanks

Make sure you have securely connected both the four pin and 24 pin motherboard power connectors into the motherboard. If either one of these are even partially unplugged it can cause your system to freeze. Also, since you have been working inside the computer, try pushing the RAM in, just in case it came loose. If you are still encountering problems check all the rest of the power and data connections inside your computer including hard drives and the new video card.

WANT TO SEE DIAGRAMS OF A T650-8B7H ASPIRE COMPUTER COMPONENTS ie the inside parts motherbody ,power suply,processor,hard drive and sound and video cards

This is a PDF Service Manual for the Acer Aspire T650 series desktop computers, from Acer Support,

After you click on the link you won't see anything happening for up to 30 seconds. The file is downloading in the background.

If you see the first page, and the file is still downloading, let the file download all the way before looking though it.

(Should the Service manual link not work for you, state so in a Comment)

Proper computer speak for motherboard is Mainboard. The mainboard is shown on Page 15.
Connections to the Headers on the motherboard, are shown on Page 19.

Orienting the motherboard so the Processor is to the top, and Ram Memory slots to the right, the Front Panel header is on the bottom right of the motherboard.

The Front Panel header, is where the various cables from the Front Panel of the computer go.
(Front Panel being the plastic panel in the front of the computer. For this computer, the Power On button, two USB ports, Speaker/Headphone jack, and Microphone jack are in the front panel)

To the left, and down a little bit, of the processor socket is the 4-pin ATX +12 Volt header.
Square in shape, white in color, 4 socket holes.

This is where the 4-pin ATX +12 Volt power cable plugs into. (Two Black wires, two Yellow wires)
This is power for the Processor. If it isn't hooked up, the Processor won't turn on. No power.

Below the Processor socket's left corner is the header for the System Fan. The computer case fan. You will see there are 4 pins.
One for 12 Volts.
One for Ground.
One for detecting the RPM's of the fan. (Revolutions Per Minute)
One for varying the RPM's of the fan. This is the sensor connection.

To the upper right of the motherboard is another small white header. (Connector) This one has 3 pins. This is where the Processor (CPU) fan plugs in.

The long white connector below the CPU fan header is a 24-pin ATX main power connector.
The 24-pin ATX main power cable plugs in here.

The Front Panel header, or PANEL 1, is on the very bottom right.
Has two rows of pins.

Starting from the left side going right, there are 4 pins, NO pin, then 3 pins on the Top row.

Starting from the left going right, there are 7 pins across the bottom.

The pins on the Bottom are numbered Odd.
Starting from the left going right, the pins are numbered,
1, 3, 5, 7, 9, and 13.

The pins on the Top are numbered Even.
Starting at the left going right the pins are numbered,
2, 4, 6, 8, NO pin, 12, and 14.

1) Pins 2 and 4 are for the MSG LED
(Pin 2 is for the + positive connection)

2) Pins 1 and 3 are for the HarDDrive activity LED
(Pin 1 is for the + positive connection)

3) Pins 5 and 7 are for the Reset switch. (Button)
(Pin 7 is for the + positive connection)

4) Pins 6 and 8 are for the Power On switch.
(Pin 6 is the + positive connection)

5) Pins 11 and 13 are for the ODD LED
(Pin 11 is the + positive connection)

6) Pins 12 and 14 are for the LAN LED

Page 116 shows an exploded diagram of the inside, of the T650.

Acer doesn't give info as to who made the motherboard for them. (All pre-built computers have their parts made by someone else)

Due to it's square shape it's a Micro-ATX form factor motherboard.
9.6 inches by 9.6 inches, or 244mm by 244mm.
(The Micro-ATX form factor can be as small as 171mm by 171mm.
The following will give you more information, )

Information about the Aspire T650 motherboard from me,

1) Motherboard chipset:
The motherboard chipset, is what determines what components are supported on a motherboard.
(Chip and Chipset are slang terms for I.C. Integrated Circuit)

The motherboard chipset is the Northbridge and Southbridge chip.

The Northbridge chip determines what Processors, and Ram Memory are supported, as well as what High Speed graphics are supported.

(The Northbridge chip handles the faster processes of the computer.
AGP and PCI Express are high speed graphics.

Any graphics card inserted into a PCI slot, is low speed graphics. This is handled by the Southbridge chip. It's a slower process. Integrated graphics are also handled by the Southbridge chip.

You may wish to view this motherboard diagram,

CPU stands for Central Processing Unit, or for short - Processor)

The Aspire T650 motherboard has an LA 775 processor socket.
The Northbridge chip is an ATI RC410
The Southbridge chip is a ULI M1573

Underneath the processor socket is the Northbridge chip. It's sitting diagonally, and has an aluminum heatsink sitting on top of it.

Below the Northbridge chip is a PCI-Express x16 slot used for a graphics card.

Below the PCI Express x16 slot is a PCI Express x1 slot. White in color, much shorter than a PCI slot.
There are two white PCI slots below the PCI Express x1 slot.

To the right of these white PCI slots is the Southbridge chip. ULI M1573
To the right of this chip are 4 SATA headers.
Below the 4 SATA headers is the Front Panel header.

Are you having problems connecting components?
Do you need to know what components you can upgrade to?
(Processor, Ram Memory, graphics card, power supply, etc)
If so, simply state what information you need in a Comment.

I am about to switch out the motherboard for m5640 aspire 1

New motherboard will have a picture of the pin connections and where they connect on the motherboard. Just follow these connections, also the wires leading from the from the front of the case to the motherboard are labelled as to what they connect to. As a final note, the white wire on the connectors is usually always the ground wire, so look at the drawing carefully to see which side is the positive and make sure that the coloured wire goes to the positive side not the white.
