The actual Processor fan connects to the CPU Fan header on the mainboard. It's 4 small pins. It plugs in right near the CPU socket on the mainboard. Check the user manual for exact placement, you may download it from the AOpen website if you don't have one already.

Plug in the 20Pin connector if that is the most Pins that the mainboard will allow. Cable tie the other 4Pins back onto the 20Pin connector.

Then if there is additional 4Pin connector required by the mainboard for CPU power and you don't have that connector on you power supply, you will need to purchase a Molex to 4Pin CPU power connector. When you go to the computer store check with them that all is correctly connected.

Take care!

What power supply connector will work with the ms8137c motherboard (aka, 20 + 4 pin)


Ahem, you just posted 20 + 4-pin.

That means it can be a 20-pin ATX main power cable, OR a 24-pin ATX main power cable.

Most power supply's now have a 20 + 4-pin power cable.

Use the 20-pin connector, or add the additional 4-pin connector, to make a 24-pin ATX main power cable.

Example.

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20plus4

In direct answer to your question, however, it uses a 20-pin ATX main power cable.

For additional questions post in a Comment.

SMPS CONNECTION DIAGRAM


Not a problem, but it would be handier to have the manufacturer Name, and Model Number.

(Back of computer on a sticker, next to the Windows product key, or up on the side of the computer tower )


SMPS = Switched-Mode Power Supply. The style used in personal computers now,

http://en.wikipedia.org/wiki/Switched-mode_power_supply

A) Main power cable:
There are three styles;

1) The old AT style that has two separate connectors. The connectors BOTH connectors have BLACK wires towards one side.

The connectors also have ONLY one way, (Direction), they can be plugged onto the motherboard.
This is due to the Lock, and Locating Tab on the motherboard connector/s, and the main power cables connector/s.

When you can plug the connectors on the motherboard, with both connector's BLACK wires facing each other, (They will be in the middle), you have them installed correctly,

http://www.playtool.com/pages/psuconnectors/connectors.html#oldpc

2) The newer ATX style. Uses one power cable, and connector.
First style to come out was the 20-pin ATX main power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

20-pin ATX main power cable's connector, has a LOCK on one side.
This Lock locks over a Locating Tab, on the female motherboard connector.

To remove this power cable you squeeze in on the Top of the Lock.
The Lock operates like a see-saw on a playground. When you squeeze the top in, you remove it's hooked end away, from the Locating Tab of the motherboard connector.

To be ensured that this cable is plugged in tightly, and correctly, the Lock's hooked end will be over the Locating Tab, on the motherboard connector.

3) The newest style is the 24-pin ATX main power cable.
As computer hardware evolved, and became better, it demanded more power.
The extra 4 pins of the 24-pin ATX main power cable provided this,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

[ Aftermarket power supply manufacturers, provide power supply's with a 20 + 4-pin ATX main power cable, usually.
You can use it as a 20-pin ATX main power cable, or use the additional 4 pin cable, and use it as a 24-pin ATX main power cable ]

4) Motherboard didn't provide enough power for newer Processors.
The 4-pin ATX +12 Volt power cable was brought out.
(Has Lock with Locating Tab on the motherboard connector, also)

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

5) Motherboard didn't provide enough power for high-end graphics card.
4-pin ATX +12 Volt power cable didn't help.
The 6-pin PCI Express power cable was brought out,

http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress

Plugs into a graphics card.

[ Note*
In all power cables, Red wires are 5 Volts. Yellow wires are 12 Volts. ALL Black wires are Ground wires ]

Next in line was two versions of the 8-pin power cable.

A) 8-pin EPS +12 Volt power cable.
Originally brought out for server computers, that has multiple Processors.
Plugs into the motherboard.

B) 8-pin PCI Express power cable.
Brought out for more power, than a 6-pin PCI Express power cable could put out.
Plugs into a graphics card.

(6-pin PCI Express power cable is capable of handling 75 Watts.
8-pin PCI Express power cable will handle 150 Watts )

If you have an IDE (PATA) harddrive, a 4-pin standard Peripheral power cable is what you need. ('Molex' is the slang term for it's connector)

If you have a SATA harddrive you need a 15-pin SATA power cable.

NOTE*
IF, your SATA harddrive has a provision for a 4-pin standard Peripheral power cable, AND a SATA power cable;

ONLY USE the SATA power cable!

If you use both you will burn out the harddrive. Maybe not immediately, but I assure you down the road you will.
(Do not use just a single 4-pin standard peripheral power cable, either)

Optical drive/s use a 4-pin standard Peripheral power cable, if they are IDE (PATA) units.
If they are SATA units they use a SATA power cable.

The old Floppy Drives use a 4-pin small Peripheral power cable.
Same cable plugs into a Card Reader, also.

The plastic front of your computer is the Front Panel.

The area of contact pins on the motherboard, that the cables, (Wires), from the Front Panel go to, is the Front Panel header.

Sometimes abbreviated on the motherboard as;
F_PANEL 1, or FP1, etc.

I will need to know the computer manufacturer name, and Model Number, (HP = Product Number, or P/N), or the manufacturer name, and Model Number of the motherboard, to TRY to provide this information.

Dear Sir, my mother board d101 has been damaged can i use of p4sd m/b insted of that while i want all rest parts remain using i dont want change ram,SMPS, Proccesser etc.


fbhushan, the Intel D101GGC motherboard (Grand Country) supports;

1) Intel Pentium 4, Intel Celeron D, and Intel Pentium D processors that fit in an
> LGA 775 processor socket.

http://en.wikipedia.org/wiki/LGA_775

The Processor has the socket holes, and the processor socket (LGA 775) has the pins.
775 socket holes, and 775 pins.

The Front Side Bus (FSB) can be either 533MegaHertz, or 800MHz.


2) Supports DDR Sdram ram memory at either 333MegaHertz or 400MHz.
(PC2700 and PC3200, respectively)

Will support Up To 2GB of ram memory.
Has two ram memory slots. The maximum amount for EACH slot is 1GB


3) The SMPS used for it has,
A) One 24-pin ATX main power cable

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

B) One 4-pin ATX +12 Volt power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4


The Intel D101GGC motherboard has Four SATA headers (Connectors) on it, so I'm going to assume you are using a SATA harddrive.
This would mean the SMPS you are using should have at least one SATA power cable.

It should also have an assortment of 4-pin standard Peripheral power cables.
(Misnomered as 'Molex')



The Asus P4SD (Motherboard chipset Intel 865PE) supports;

1) Intel Pentium 4 and Intel Celeron processors that fit in a > Socket 478 processor socket

http://en.wikipedia.org/wiki/Socket_478

The Processor has the pins, and the processor socket has the socket holes.
478 pins, and 478 socket holes.

Your Processor will NOT work.

The Ram Memory WILL work.

The SMPS MAY work.

I state MAY because the Asus P4SD motherboard uses a 20-pin ATX main power cable.

If the last four pins of the 24-pin ATX main power cable that you have on your SMPS right now, Do Not remove, you can Carefully cut them off. Wrap them up, and out of the way.
If you need guidance on this I can help instruct you.

You need an IDE (PATA) harddrive, or a SATA adapter card to use a SATA harddrive.

So there you have it sir.

Most motherboards now have a 24-pin power supply connector. If you haven't already found a diagram showing the pinouts of the 20- and 24-pin power plugs, here's one borrowed from a handy site:

pgh_pa_guy_1.jpg

The two plugs are essentially the same, but the 24-pin version duplicates some voltages on the extra pins. The extra pins in the larger connector were meant to provide extra current paths for voltages that see heavy loads from newer processors and motherboard circuitry. Depending on how a motherboard is designed, it might work with a 20-pin plug connected (leaving pins 11, 12, 23 and 24 empty). But typically if the board has a 24-pin connector it needs the 24-pin power supply plug.

Most power supplies have a 20-pin plug with a separate 4-pin section that fastens to it for connection to a 24-pin mobo connector. It typically has one side designed to slide onto the end of the 20-pin plug, essentially turning it into the 24-pin version. This added plug does not have a retaining clamp on its side, so you can tell it from the the 4-pin CPU power plug. The wire colors are also different. For reference, here is the processor power plug, from the same website:

pgh_pa_guy_2.jpg
New motherboard specs call for the separate processor power connector for the same reason the extra pins were added to the power supply connector: to handle the high currents needed by increasingly faster CPUs.

When the motherboard has these connectors, you need to use them all to get everything working. Hope this helps. Thanks to smspowersupply.com for the diagrams, and thank you for using Fixya.

I have unpluged the 20 pin ATX Power Connector on the PTGD-LA motherboard, there is a 24 pin plug, I am not sure where to plug it in. I can only find manuals for the PTGD1-LA which shows a 24pin/24plug.


If the motherboard has a 24-pin socket, you need a 24-pin connector on your power-supply.
If the motherboard has a 20-pin socket, then only 20-pins from the connector need to be connected to the motherboard.

It sounds like you have a faulty connector - I would return the item under warranty. Otherwise, if it is out of warranty, you will have to source a new motherboard.

How to use ATX-250-12z SMPS with 24 pin


Chances are that 250w power supply is not going to power a motherboard with a 24 pin connector, but you can try.
You will need to purchase a 20 to 24 pin adapter cable.

Hmmm.... mainly you have:
-20 or 24-pins connector, that is unique and goes directly to motherboard (powers motherboard and its components)
-4 or 8-pins connector that powers CPU
-the rest would be connectors for ROM (CD/DVD/BlueRay) and HDD devices (there are: molex and sata power conectors)

ATX Motherboards and power supplys are standard the connections are the same however there are now 2 types an 20 pin and a 24 pin varient - the extra 4 pins supply extra power to the power hungrey motherboards needed for morder dual core processors and graphics cards - you can use a 20 pin connector on a 24 pin board but don't overload it with graphics and pwerful proccessor or it will fail, alternatively go toyou local PC hardware store or internet supplier and purchase a new PSU to the same spec as the board - your manual will tell you the minimum spec you should need. - it all depends on the combination of processor memory, grachics other bus cards (audio NIC etc) and how many peripherals (HDD's and CD/DVD/Blue ray you have in the unit if you worried look at the specs for each unit you have in your PC - add the wattage together and then ad at least 25% for overhead if your current PSU is with spec then just carry on - it is not advisable to go around and try and rewire a PSU not for the £20 it costs to replace it
