Usually the connectors will be marked as in the picture, indicating their usage. CONNECTOR PROBLEM - 07471ce.jpgIf your connectors do not have a label printed on them you can figure out the important ones. You will have a pair of connectors each for the power switch, the reset switch, the power LED and the hard drive LED. 
The two pairs of wires used for the switches are the important ones. They can be identified with a circuit tester or multimeter (Check for resistance/Ohms). When they are pressed, the meter should indicate a connection across the two wires. In the case of the power switch if it's a really old case it will toggle on and off, so watch for the continuity to change when you press it. Otherwise the reset and power switches will only register a connection when pressed, and revert to an open circuit when released. Use your multimeter to identify which pair reacts to which swtich, and label them with some masking tape and a sharpie (or equivalent way). 
As long as you identify these two and connect them correctly you'll be okay. The LEDs are not essential to booting your system and you can figure them out later. LEDs have to be connected the correct way around (usually the white wire is negative), while the switches don't matter which way they are connected as long as it's to the correct two pins. You can connect the LEDs and see which ones light up on your panel to determine which is connected where. If your power-on LED lights when there's hard drive activity, then you know that the connector plugged into the pins for HDD LED is the wires for the power LED, and so forth.

Hope this helps.

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.

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.

[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.

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',

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

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

Find socket for hard drive

HP part number 5188-5473 brings up the Asus A8N-LA motherboard, made especially for HP,

The rest of the number/letters do me no good.

I will elate some information based on the above, and see if it does you any good;

1) The Asus A8N-LA has connectors for two types of Harddrives;

A) IDE. Also known as PATA.

This type of Harddrive uses a flat ribbon IDE(PATA) data cable,

Another look,

(The Asus name probably won't be on it. These two IDE data cables just happen to be made by Asus )

The connectors on each end have 40 socket holes. One socket hole will be blocked off. (Or should be) ONLY 39 socket holes are used.

A look at the connector on the motherboard;

Looking at the motherboard illustration, look at the Bottom/Right corner. There are two IDE connectors. They are marked as IDE 1, and IDE 2.

Scrolling down a little bit to the motherboard photo, you will see IDE 1 connector is Black in color, and IDE 2 is Blue in color.

The IDE (PATA) harddrive's data cable goes to IDE 1.
Optical drive/s (CD/DVD drive) goes to IDE 2.

This is the type of power cable from the Power Supply, that goes to an IDE (PATA) harddrive,

There is usually a square, or rectangle, or two bumps; used on the IDE ribbon cable connector, to line up with the connector on the motherboard, or harddrive, or optical drive.

It is called a Locating Lug.

This particular IDE data cable connector, has two raised bumps, for a Locating Lug.

It lines up with a Cutout in the motherboard's connector, or the harddrive's connector, or the optical drive's connector.

IF, there is NO Locating Lug, use the faint Red stripe on the side of the IDE data cable.
The red stripe is on the same side as Number 1 wire.

Number 1 wire goes to number 1 pin.
On a harddrive, or optical drive, number 1 pin is ALWAYS closest to the power cable connection,

Looking at the photo number 1 pin is on the Right side. It is closest to where the 4-pin Peripheral power cable plugs in.


Looking at the motherboard photo, the Yellow, and Blue, and Black, and White connectors; to the left of the Blue IDE connector, and Black IDE connector; are SATA connectors.

SATA 1 is Black. This is where the SATA harddrive's data cable, is supposed to plug in.

The BEAUTY of SATA though, is that you can plug the harddrive into ANY of those SATA connectors on the motherboard, and BIOS will find the harddrive. (Or any other peripheral device)

An example of a SATA data cable, and it's connector,

The red SATA connector shown below the SATA cable example, is just a different style of SATA motherboard connector; than what your motherboard uses.

Note the L-shaped opening in the SATA data cable's connector.
Lines up with the L shape on the motherboard connector, or harddrive connector, or optical drive connector.

Most SATA data cable connectors, also have a Lock on them.
Sometimes it's a Lock you can easily see.

Most times, it is a small depression you depress with your thumbnail, or a little 'bulb' you depress.
Depress/unlock to plug the cable in, or remove the cable.

The 90 degree angle connector end, (As shown), plugs into the harddrive, or optical drive. The Straight connector end plugs into the motherboard.

This is an example of a SATA power cable,

Between it, and the SATA data cable connector, it is the larger of the two.
SATA power cable connector has 15-pins.
SATA data cable connector has 7-pins.

Also note the rectangular depression on the SATA power cable's connector. That is where you depress to unlock the connector.
The SATA power cable's connector also has an L-shaped opening.

2) IF, you are trying to hook up a laptop harddrive to this motherboard, you need to determine if the laptop harddrive is an IDE (PATA) type, or a SATA type.


There is a label on the laptop harddrive. It has the manufacturer code on it. Type the number/letters in your browser search bar, and click on the search icon. (Magnifying Glass)

Now purchase an external enclosure.

The external enclosure opens up, and the laptop harddrive goes inside, and plugs into an interface.

Close the external enclosure, and plug it's USB cable into any available, open USB port on your computer.

It will be a 2.5 external enclosure.
Harddrive's are measured across their width.

A desktop harddrive is 3.5 inches across in width.
A laptop harddive is 2.5.

Example of a 2.5 IDE (PATA) external enclosure,

Example of a 2.5 SATA external enclosure,

Widetech the max psu update, now black screen on monitor

Kind of hard to give you a cable diagram, Roslyn, when you haven't stated what motherboard manufacturer and model number.

Or computer manufacturer and model number.
(Back of computer next to Windows product key; or up on side of computer tower )

So we'll wing it..............

Widetech the Max. A modular line of Power Supplies.

1) Main power cable;
It will be either a 20-pin ATX main power cable, or a 24-pin ATX main power cable.

The WTM (Widetech the Max) will have a braided thick cable, that will have a 20-pin connector, and a 4-pin connector.
Looks like this,

The 20-pin connector, and the 4-pin connector, should have a white arrow on the side. The arrows point to each other, when the two connectors are properly aligned with each other.

So, ATX main power cable plugs into Power Supply, (If removable), and 20 + 4-pin connector plugs into motherboard.

When the hooked end of the Lock, on the side of the power cable's connector; is over the Tab on the motherboard connector; the power cable is deemed to be plugged in properly, and tightly.

Orange wires are 3.3 Volts
Red wires are 5 Volts
Yellow wires are 12 Volts.
Black wires are Ground wires. (Also are Negative)

Note that the extra 4-pin power cable, that attaches with the 20-pin ATX power cable; has TWO Yellow wires, a Red wire, and a Black wire.
This way you don't accidentally somehow, plug the following power cable, in with the 20-pin ATX main power cable,

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

When Processors started using more power, than just the processor socket (Motherboard) could deliver, this power cable was brought out to help carry the load.

TWO Yellow 12 volt wires, and TWO Black ground wires.

3) 8-pin EPS +12 Volt power cable:

Brought out for motherboards supporting multiple Processors, (CPU's), such as a server computer; but with processors needing more, and more power; is used quite frequently by motherboard manufacturers now.

NOTICE the power wires. The color code of the insulation of the wires.
FOUR Yellow wires (12 Volt), and FOUR Black wires. (Ground)
NOT to be mixed up with the following power cable,

This baby plugs into a GRAPHICS CARD (Video Card. Same/same)
A PCI Express graphics card, IF it uses one.

The PCI-Express x16 slot on the motherboard, is only capable of delivering 75 Watts.
This power cable can deliver UP TO an additional 150 Watts.

It is an upgrade of this power cable,

The 6-pin PCI Express power cable was brought out, to provide more power for a graphics card.

75 Watts.

So now you have the PCI-Express x16 slot on the motherboard capable of 75 Watts, and the 6-pin PCI Express power cable capable of 75 Watts; for a total of 150 Watts available for a graphics card.

PCI-Express x16 slot on motherboard, and 8-pin PCI Express power cable?

225 Watts.

This power cable,

Is for a motherboard that uses a 4-pin ATX +12 Volt power cable, OR an 8-pin EPS +12 Volt power cable.
Is a combined power cable if needed, just like the 20 + 4-pin ATX main power cable.

This power cable is a SATA power cable,

Used to plug into a Harddrive, or Optical Drive. (CD/DVD drive)

IF your SATA harddrive has a provision on the back; to plug in EITHER a SATA power cable, AND a 4-pin Peripheral power cable; ONLY use the SATA power cable.

Using BOTH power cables will burn up the harddrive. May not happen immediately, but I ASSURE you it will happen.

4-pin Peripheral power cable, is also erroneously known as a 'Molex' power cable.
Molex was the first company with the CONNECTOR design. The name stuck. Kind of like calling an adjustable open-end wrench, a Crescent wrench,

[ IDE (PATA) harddrive shown in photo. Not a SATA harddrive ]

Note that between a SATA power cable, and a SATA data cable; the SATA power cable's connector is longer.
SATA power cable connector has 15-pins.
SATA data cable's connector has 7-pins,

Note the L-shaped opening of the SATA data cable's connector; and the L-shape of the motherboard connector.
The SATA power cable has the same L-shaped opening.

NOTE that color of connectors does NOT matter.
Could be green with pink polka dots.
It is the wire color code, and connector SHAPE, that matters.

[Applies to ALL cables, and connectors}

Sometimes the SATA power cable, and SATA data cable connectors; have a lock on them.
May not see it very well. It is usually a slightly raised bump on the connector. This is depressed with a thumb nail to unlock.

Unlock WHEN installing, and removing.

ALWAYS use the connector when plugging in, or unplugging a cable.
DO NOT pull on the wires.
(Even if you have to stand on your head, and whistle 'Dixie')

I lay the computer opening side UP, on a static free towel, on a table. Much easier to get to the cabling.

ONLY plug in the cables you need, to the Power Supply.
That's what Modular cabling is all about.
Gives more room when not using unnecessary cables, and more air flow through the computer case; for cooling.

I just installed a ThermalTake TR2 600 power supply. It is Modular Cabling also.

I'm willing to bet you didn't plug the Processor (CPU) power cable in.
Either a 4-pin ATX +12 Volt power cable, OR an 8-pin EPS +12 Volt power cable.

Make sure the Ram Memory is seated tightly also.
It get's bumped loose when installing a Power Supply.
No, CANNOT just visually inspect, and let it go at that.

You HAVE to remove ALL ram memory modules ('Stick'), and plug them back in again; to be ASSURED that they/it are seated tightly, and correctly.

Well that about does it for me kid, post back in a Comment if you have additional questions.

Is there a schematic somewhere that shows how to plug these things in? I may be short a cord Thanks! Jack

First thing to plug in are the Power Supply cables.

The main one to start with is the ATX main power cable.
There are two main variations of the ATX main power cable.

The 20-pin ATX main power cable,

,and the 24-pin ATX main power cable,

The 20-pin version was used on the older model computers. It was found that more power was needed to the motherboard due to newer computer components, and four extra power wires were added.

In the center photo note the lock on the side of the connector. It operates in a see-saw fashion. The top is squeezed in, to release the hook of the lock from a tab on the female connector, on the motherboard. Then the male connector can be removed from the connector on the motherboard.

Depending on the motherboard you may also have a 4-pin ATX +12 volt power cable. This is additional power to the motherboard, and is mostly used to provide additional power to a Processor.

Note the lock on the side of the connector. It operates in the same fashion as the ATX main power cable's connector.

Peripheral devices inside the computer also require a power cable.
If you have an IDE, (Also known as PATA), harddrive it will require a 4-pin standard Peripheral power cable.
Commonly misnomered as a Molex power cable,

This power cable is also used on IDE type optical drives. CD or DVD.
It can also be used along with an adapter cable to power a computer case fan.
There is no lock, but there is only one direction the cable will plug in.
There are two rounded corners on one side of the plug to line it up.

On all power cables use the connector itself to unplug the cable, Not the wires!

(Sometimes unplugging a 4-pin standard Peripheral power cable is tough.
The connector is rocked side to side while removing.
Sometimes an additional tool is needed to EASE the connector out.
In all cases make sure the computer is unplugged from power BEFORE working on it, and assure that you are following Anti-Static Precautions)

You may have a SATA harddrive, and also you may have SATA optical drives. (CD or DVD drive)
They use a SATA power cable.
The SATA power cable has 15 pins.

[Note a SATA data cable has 7 pins. It is the shorter of the two cable connectors]

IF you have a SATA harddrive that has provisions on the back of the unit, to plug BOTH a SATA power cable, and a standard 4-pin Peripheral power cable, ONLY use the SATA power cable!

Using both power cables will burn out the harddrive.
Sometimes it doesn't happen right away, but it eventually will.

The last power cable I will mention here is the 4-pin small Peripheral power cable.
On older computers this power cable was used on a Floppy Drive.
Now more used to provide power for a Card Reader.

How to connect the front penal with motherboard

To connect the front panel of your case with your motherboard, it is quite easy.

If you have the motherboard manual, I will help you on connecting the cables to the motherboard.

In summary, the pins or connectors for the front panel are on the same spot of the motherboard.
If you don't have the manual, check on the motherboard, THere are like 8 or 10 pairs of pins which are labeled.

The speaker cable is a 4 pin conector. See the speaker's pin on the motherboard.
The Power cable will fit into a 2 pin connector.
The HDD Cable as well
The reset. too..

The colored cable is always +, the black cable is always -
The + usually goes on the first pin of the assigned connector.

For example: motherboard connector is:

The cables goes on the Jumpers area.

You will see somthing like this:

Hope that helps

According to the internet, your computer has an Intel 845GV chipset motherboard. Intel tends to use a generic pattern for connecting the front panel connectors. A description can be found on intel's site.
If this doesn't solve your problem, comment back with the motherboard model number. Look on the board, it should be printed somewhere, and it should start with D845GV...something something...

To connect a unit with a computer 1km away..

There are easier ways of doing this. If you simply want to extend the length of the Cat 5-e cable they make simple connectors which do so. You must make sure the cable is a STRAIGHT SHOT cable and not a crossover cable though. A wire tester would work to look at the configuration but you can look very closely to the color coordination inside the connector and figure out which configuration the cable is. If the colors are int he same order on both sides then you have a straight shot cable.
