Verifying power connection 20/24 pin?

3500g mb has a 24 pin atx power supply socket and Sata drives but power supply has 20 pin with 4 pin split that does not fit into the rest of the 24 pin socket. I think I replaced the power supply and it worked with only the 20 pin plugged in. Now I'm following someone else troubleshooting the now non booting machine. Does this mb use the 20 pin socket only?

DX4820 power supply


To my knowledge, the Power Supply used is just the common ATX form factor design.

Approximately 6 Inches Wide, 5-1/2 Inches Long, and 3-1/2 Inches Tall.

Needs these power cables;

A) 24-pin ATX main power cable
Newer power supply's come with a 20 + 4-pin ATX main power cable.

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

That is so the power supply can be used on a motherboard, that needs a 20-pin, OR a 24-pin ATX main power cable.

B) 4-pin ATX +12 Volt power cable.
Often referred to as an ATX12V power cable.

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

[Note color of power cable connectors does NOT matter ]

Note the Lock on the side of the power cable's connector, and matching Tab on the motherboard connector.
The 20 + 4-pin ATX main power cable, and matching motherboard connector; has this type of Lock/Tab also.


C) Needs at least 2 SATA power cables.
The Harddrive is a SATA unit, and I believe the optical drive (CD/DVD drive) is too.

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

Often has a Lock on the connector. Press to release when installing, or removing.

D) Should have at least two 4-pin (Standard) Peripheral power cables.
Misnomered as 'Molex',

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

E) Needs one 4-pin (Small) Peripheral power cable, for the Card Reader.

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

Also needs 300 Watts.
A Power Supply like this one would work,

Gateway dx4822-01 power supply


Gateway DX4822 Desktop PC,

http://support.gateway.com/us/en/product/default.aspx?tab=1&modelId=2291

Just a regular Ol' ATX power supply. Rated at a maximum wattage rating of 300 to 525 Watts. Two different power supply options offered.

Power Supply case size is;
6 Inches Wide, by 5-1/2 Inches Long, by 3-1/4 Inches Tall. (152.4mm Wide, by 139.7mm Long, by 82.55mm Tall )

Has the following power cables;

A) 1 -> 24-pin ATX main power cable,

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

[ NOTE* Color of connector on power cable, OR motherboard, does NOT matter.

Proper connector, proper power cable, DOES matter; connector color does not matter ]

B) 1 -> 4-pin ATX +12 Volt power cable,

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

{ Power to the motherboard, and all components connected to it }

C) 2 or more -> SATA power cables,

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

{ Power to a SATA harddrive, and/or power to SATA optical drive/s.
(CD/DVD drive) Or power for an upgrade in the future, for a SATA optical drive }

D) 3 or more -> Standard 4-pin Peripheral power cables,

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

{ Power for an IDE (PATA) harddrive, or drives. Also power for IDE (PATA) optical drive/s. Plus power in some instances, for computer case fans }

E) Two or more Small 4-pin Peripheral power cables,

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

{ Listed as a Floppy Drive power cable. Back in the day when the article was written, such was true.
It can still be used for a Floppy Drive, but is more used now as a power cable for a;
1) Card Reader.
2) Computer case fans (IF needed }

It's name is Small 4-pin Peripheral power cable. It is smaller than it's larger cousin, the Standard 4-pin Peripheral power cable.

Also has smaller gauge of wiring. This means it cannot carry the same amperage, as the standard 4-pin Peripheral power cable.

I would recommend this,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=899124&CatId=1483

A) 1 -> 20 + 4-pin ATX main power cable.
Can be used as a 20-pin ATX main power cable, or a 24-pin ATX main power cable, which is what you need.

B) 1 -> 4-pin ATX +12 Volt power cable.

C) 6 -> SATA power cables

D) 4 -> Standard 4-pin Peripheral power cables

E) 1 -> Small 4-pin Peripheral power cables

F) 1 -> 6-pin PCI Express power cable

G) 1 -> 6/8-pin PCI Express power cable.

In the future, (Or now if you have one), you can upgrade to a better graphics card, that needs an additional power cable, IF you wish.
The 6-pin PCI Express power cable.

You also have a 6-pin or 8-pin PCI Express power cable.
(6/8-pin PCI Express power cable)

All the pins can be used together, and make an 8-pin PCI Express power cable, for a very powerful graphics card that requires this cable.

Just added bonuses with today's modern power supply's.

I replaced my power supply and don't remember where the connections went


Not too much way you can go wrong. There's a 20 or 24-pin connector which plugs into the motherboard in only one place. There probably is a 4-pin connector and that, too, goes into the motherboard (in a socket near the CPU). The other connectors are power connectors for you hard drive and CD/DVD. That's about it.

Not sure which plugs go where on the bestec atx300 power supply for gateway computer. remopved the old powere supply, but don't know which plug goes where on the new one.


I'll assume that your old PSU is also an ATX. First, the plug that has a few dozen wires arranged in a rectangle goes into the MB. Your PSU's ATX connector may be split into 2 parts: the AT portion and a square portion with 4 wires. Together, they make an ATX plug. You'll find some tiny plugs with 2-3 wires for your onboard fans. You might find a few slightly larger flat plugs with 4 wires for old floppy drives. The rest should be the regular MOLEX plugs and slim SATA power plugs for your drives.

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:

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00361570&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=459491

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,

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

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,

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

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,

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

(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'),

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

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)

The power supply light is flashing and my computer won't start up. No fan, nothing. I disconnected the power to the mother board and the light burned solid when plugged in. I have switched the watts...


Bad Power Supply.
Weak voltage power rail, or rails.
{There are three voltage power rails.
1) The 3.3 Volt power rail
2) The 5 Volt power rail
3) The 12 Volt power rail}

The flashing Green LED light is one direct indication of this for HP computers.
Usually there is at least enough power to light LED lights, and spin fans, but your Power Supply doesn't even have that much power.

1) All of the LED lights on at once use less than 1 Watt of power
2) EACH fan uses 2 to 3 Watts of power
3) A typical Processor can use 51 to 125 Watts of power.
Depends on what Processor it is.

The HP Pavilion A847C desktop computer has an ATX power supply, with a maximum rated wattage of 250 Watts.

The ATX form factor for a Power Supply refers to it's case size, for one.
5-1/2 inches Long, 3-1/2 inches Tall, and 6 inches Wide
The common type of Power Supply used in over 80 percent of PC computers out there, and readily available all over.

Click on Product information in the list
Now click on Product specifications

Finally click on > Motherboard Specifications, PTGD1-LA (Goldfish )

Scroll the page down to view the motherboard illustration and photo.


The replacement Power Supply has to have,

A) A 24-pin ATX main power cable.
In the motherboard photo, view the Ram Memory slots. The long Blue, and Black slots.

To the right of the bottom corner of the Black ram slot (Slot 4) is a whitish connector.
Two columns of 12 socket holes.
This is where the 24-pin ATX main power cable plugs into.
(ATX Power Connector in the motherboard illustration)

Typical 24-pin ATX main power cable,

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

NOTE the Lock Clip on the side of the connector.


B) 4-pin ATX +12 Volt power cable.
At the bottom Left corner of the Processor socket is a whitish square connector.
4 socket holes.
This is where the 4-pin ATX +12 Volt power cable plugs into.
(ATX12V in the motherboard illustration)

Typical 4-pin ATX +12 Volt power cable,

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

NOTE the Lock Clip on the side of the connector.

{The top of the Lock Clip is squeezed in to release it, and is held while the power cable is removed.
Same for the 24-pin ATX main power cable's connector}


C) SATA power cable.
Used for the SATA harddrive

The SATA power cable has 15 pins, and is the longer connector.
The SATA data cable has 7 pins, and is the shorter connector.

IF, the SATA harddrive has provisions for plugging in a SATA power cable, AND a 4-pin standard Peripheral power cable, ONLY USE the SATA power cable.
Otherwise you will burn up the SATA harddrive.

The SATA power cable plugs into the SATA harddrive.
One end of the SATA data cable plugs into the motherboard, and the other end plugs into the SATA harddrive.

Below the ram slots in the bottom Right corner are the SATA headers on the motherboard, that the SATA harddrive plugs into.
The Blue, Orange, Black and White connectors.

Of course the SATA harddrive only plugs into one of them.
Looking at the motherboard illustration you will see they are numbered.
SATA 1, SATA 2, SATA 3, and SATA 4.

IT DOESN'T MATTER which one you plug your harddrive into. (Or any SATA device)
That's the beauty of SATA.
BIOS will find the harddrive.
But for you, it will be easier to keep track of where the SATA harddrive is plugged in, if you just use SATA 1.

Typical SATA power cable,

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


D) 4-pin standard Peripheral power cable.
Commonly referred to as Molex. (Misnomer)

Used for optical drives, Fans, and other associated hardware.

Typical 4-pin standard Peripheral power cable,

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


E) 4-pin Small Peripheral power cable.
Used to be commonly used for a Floppy Drive.
For your computer it provides power to the Memory Card Reader.

Typical 4-pin Small Peripheral power cable,

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

Watch disconnecting, and connecting this connector. You can bend the pins very easily.
SAFETY
WATCH your fingers as the pins are QUITE SHARP!

All of the power cables listed above are standard for today's Power Supply's.

About the Wattage.
A computer ONLY uses the power it needs, and NO more.

If you put a 10,000 Watt power supply in, and the computer only needed 100 watts for what it is doing, it will ONLY use 100 watts.
To wit, if you install a Power Supply with more Wattage than 250 Watts, it will NOT hurt your computer.

If you need guidance in replacing your Power Supply, or recommendations for a Power Supply, please state in a Comment.

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.

Un pluged power sulp. cant remember whear they go


Would help if I had the computer manufacturer's name, and the Model number.

Generic Info:

A) Main power cable:
You may have an old computer which has an AT power supply.
This type of power supply has 2 main power cables.

Example:

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

NOTE the lock tabs on the side of the connectors. The connectors only go one way.
NOTE the Black wires in both connectors.

When both connectors are plugged in properly, the Black wires in both connectors face each other.
Look at the photo to the far right.
(The Black wires are Ground wires)

B) Newer computers past the time period of the above, use an ATX power supply. They use an ATX main power cable.

First there was a 20-pin ATX main power cable.
As time proceeded, and more power was needed to the motherboard, the 24-pin ATX main power cable came out.

20-pin ATX main power cable, and it's respective connector,

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

NOTE the lock tab on the side of the connector. It operates in the same fashion as a see-saw on a playground.

The top of the lock tab is pressed in. The hook on the bottom of the lock tab, catches on a protrusion coming out of the side of the connector, on the motherboard.

When plugging in the Lock Tab faces the 'bump', or protrusion on the connector on the motherboard.

Scroll down the page for info on the 24-pin ATX main power cable, and it's respective connector.
With either style of connector, ensure that the ATX main power cable's connector, is pushed down in the connector on the motherboard. Ensure that the Lock Tab is locked into position.

3) 4-pin ATX +12 Volt power cable.
Also referred to as P4 MB, (Pentium 4 MotherBoard), and P4 12V
(Pentium 4 12 Volt)

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

This power cable is power for the Processor.
The respective connector on the motherboard, is a square whitish plastic connector with four socket holes.
As shown on the photo to the far Left.

Different manufacturers place the female connector in different places, but it is always located somewhere near the Processor.

4) Standard 4-pin Peripheral power cable:
Also misnomered as a Molex connector.

[Name of first design stuck. Same as calling an adjustable open-end wrench a Crescent wrench]

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

This power cable is used for IDE, (PATA) harddrives, optical drives, (CD/DVD drive/s), and sometimes for computer case fans.
Note the rounded corners on one side of the connector.
Only allows installing in one direction.
(Unless you 'gorilla' it)

5) SATA power cable:

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

Used for SATA harddrives, and optical drives that are SATA.
Only plugs in one direction.

NOTE*
Sometimes a SATA harddrive, will have a provision for a standard 4-pin Peripheral power cable, AND a SATA power cable.

ONLY plug in the 15-pin SATA power cable!
I cannot stress this enough.

Plugging in both power cables will BURN up the SATA harddrive.
May not happen right away, but I assure you it WILL happen.

5) Floppy drive power cable:

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

This is another style of 4-pin Peripheral power cable. A smaller version.
Your computer may not have a Floppy Drive, and hence may not use this power cable.
If you have a Card Reader though, it uses this style of power cable.

Only plugs in, in one direction.
{NOTE*
Watch the sharp pointed pins coming out of a Floppy Drive, or Card Reader, that this power cable plugs onto!
Will stick your finger as easily as a straight pin! ]

For power cables going to a graphics card, (Video card, same same), let me know what graphics card it is.

Bad Power Supply.
Weak Voltage power rail.

The Pavilion a6000n desktop computer uses an ATX style of power supply, and is rated at 300 Watts.
(Probably made by Delta Electronics)

The ATX style of Power Supply is used in over 85 percent of PC's. Very common unit.

[Case size is approximately 6 inches Long, 6 inches Wide, and 3-1/2 inches Tall ]

What you are looking for is an ATX power supply with at Least 300 Watts, and the correct power cables.

Note that a computer only uses the power it needs, and No more.

Wouldn't matter if you had a 10,000 Watt Power Supply, (Exaggeration), and the computer only needed 100 Watts, it will only use 100 Watts.

(Surfing the internet typically uses 100 Watts.
Computer. Monitor uses it's own power, and is separate from this figure)

1) Scrolling down the page, and looking at the photo of the motherboard, you can tell the Power Supply must have a 24-pin ATX main power cable.

To the right of the Blue, and Black ram memory slots is the 24-pin ATX main power cable connector, on the motherboard.

It is White in color, and consists of 2 rows of 12 socket holes.
24 total.

On the illustration it is marked as - ATXPOWER.

This is a closer look at a typical 24-pin ATX main power cable, and it's respective connector,

Note the Lock on the side of the connector. The Lock is hinged in the middle, (Plastic), and operates like a see-saw on a playground.

Squeeze the top of the Lock in to remove the 24-pin ATX main power cable.
ONLY gently pull up on the connector, and NOT the wires.

[This action brings the hooked end of the Lock away from a 'Bump', or protrusion, that is present on the female connector, on the motherboard ]

2) The Power Supply must also have a 4-pin ATX +12 Volt power cable.

On the illustration where it states Socket AM2 is the Processor socket.

To the left, and down a little of the Processor socket, is a blank square.
The writing under it is illegible.

This is where the 4-pin ATX +12 Volt power cable plugs in.

On the motherboard photo it is to the left of the white Processor socket, and is square in shape, with four socket holes.

This is a better look at a 4-pin ATX +12 Volt power cable, and it's respective connector,

Color of the plastic used in the connectors, does not matter.

3) Looking at the Specifications page, you will see that the Power Supply must have at least 1 SATA power cable.
It's used for the 250GB SATA harddrive.

NOTE*
If the SATA harddrive in your computer has a place for a SATA power cable, and a 4-pin Peripheral power cable, ONLY use the SATA power cable.
DO NOT use both.

4) Again looking at the Specifications page, the Power Supply must have at least two, 4-pin Peripheral power cables.
Used for the optical drives.
(DVD drives)

There may be more 4-pin Peripheral power cables needed, to run any computer case fans.

[The Processor fan plugs into the motherboard ]

An example of an ATX power supply that is 500 Watt rated, and has the correct amount of power cables, plus the correct type of power cables,
