How to conect front panel

For this you need the motherboard manual.
If you do nor have it, download it.
The setup procedure will be at the beginning, after the specifications. The two cables from the front panel that are important are the (power on , LED reset) cable, and the USB cable.
Both these cables are built to the Intel developed, case standard, on most PCs.
The problems start when you are building a PC with an old case. The wires from the front panel will be all separate.
The motherboard manual will have the location of the pins, and the "pin out" for the motherboard.
The color lead is positive, and the white is negative.
The speaker wires are red and black, and the polarity does not matter.
Do them one at a time. Start with power on, when you have found the proper pins and hooked up the leads, then reset, then power LED, then HDD LED, and last the speaker.
Then find the USB pins and connect the USB cable to the motherboard.
The PC should boot, assuming the other components are installed.

Power supply diagram for ht 2000 motherboard

1) Uses one 24-pin ATX main power cable.

Motherboard installed in computer case, the motherboard connector for the 24-pin ATX main power cable; is to the Right of the Blue IDE (PATA) connector.
(Right side of motherboard)

General example. Note that color does NOT matter of connector,

2) Uses one 4-pin ATX +12 Volt power cable,

Motherboard installed in computer case, the whitish square 4-socket hole connector, to the Bottom/Left corner of the Processor socket; is the 4-pin ATX +12 Volt power cable's motherboard connector.

General example. Note color does NOT matter of connector,

THAT, would be considered a Power Supply diagram of the motherboard.

They are the only two power cables that plug into the motherboard.

The front of your desktop computer is the Front Panel.

The area of contact pins on the motherboard, that the Main wires from the Front Panel go to, is the Front Panel header.

Power On switch, Power On LED, (Light Emitting Diode), Harddrive activity LED, and a Reset switch IF used.

M3A770DE 4 pin

Due to the 'large expanse' of information you posted I can barely contain myself.

1) 4-pin ATX +12 Volt power cable, that plugs into the motherboard,

Note that this power cable has TWO Yellow 12 Volt wires.

Back in the day there was no additional power cable needed, for the motherboard.
When the Intel Pentium 4 came out, the 4-pin ATX +12 Volt power cable came out also.

Power for the Processor.

More, and more powerful hardware components for the motherboard, (Processor and graphics card), required more power to the motherboard.

The 6-pin PCI Express power cable was brought out,

This power cable was used to connect directly to a graphics card, and provide power to it.

Note that this power cable has THREE Yellow 12 Volt wires.
It can carry up to 75 Watts of power.

Still wasn't enough power TO the motherboard, and TO the graphics card, with the new hardware component technology being brought out.

The 8-pin EPS +12 Volt power cable was brought out,

Note that this power cable has FOUR Yellow 12 Volt wires.
Is capable of providing up to 150 Watts.

A PCI Express x16 slot is capable of providing 75 Watts.

Note the shape of the sockets in the connector.
Now compare to an 8-pin PCI Express power cable,

DO NOT confuse the 8-pin EPS +12 Volt power cable, with the 8-pin PCI Express power cable.
They are NOT the same.

The 8-pin EPS +12 Volt power cable's connector on the motherboard, is at the top left corner of the Processor socket, and close to the outside edge of the motherboard.

(With motherboard installed in computer case)

You can use the motherboard with just a 4-pin ATX +12 Volt power cable.

Look at the LOCK on the side of the 8-pin EPS +12 Volt power cable's connector.

With that Lock AWAY from you, or on the opposite side of the connector, a 4-pin ATX +12 Volt power cable plugs in on the RIGHT side.

If you have a powerful graphics card installed in your
PCI Express x16 -> slot/S, you had definitely better use a Power Supply that has an 8-pin EPS +12 Volt power cable.

This is a 4-pin standard Peripheral power cable,

Misnomered as a 'Molex' power cable.
{ Molex was the first to design and produce this style of power cable CONNECTOR. The name stuck. Kind of like calling an open-end wrench a Crescent wrench }

IF you use an adapter power cable; Use TWO 4-pin standard Peripheral power cables!!
You need those Yellow 12 Volt wires.

What will happen if you do not use two?

1) The PCI Express x16 slot/s will burn.

2) The gold plated contact pins on the PCI Express graphics card, or cards, will burn.

3) If the graphics card, or graphics cards, require a power cable connected to them;
A) The connections on the graphics card for the power cable will burn.

B) The power cable connector will burn.

Other than that the only other 4-pin references on the motherboard, that I can see, is the optical drive's 4-pin audio cable connector on the motherboard, (CD1), and the CPU (Processor) Fan 4-pin connector on the motherboard.

Gateway dx4822-01 power supply

Gateway DX4822 Desktop PC,

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,

[ 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,

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

C) 2 or more -> SATA power cables,

{ 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,

{ 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,

{ 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,

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 would like help on reconecting my pc cables,, the p1 - p8 from the power supply

For an Asus P4S800D-X desktop computer motherboard?
No problem, Luz.

The cables you have indicated are Power Supply cables.

Let me show where they go;

First I would like you to download the Motherboard Manual.
It will also come in handy later,

Click on the Download tab.
(Overview,Specifications,Download,Memory/Device Support,etc)

Scroll down, click on the + sign next to - Manual (6)
Scroll the page down to the bottom file, then click on the blue - Global (DLM), underneath -

Version E1753 / P4S800D-X User Manual English Version E1753

{ Note* To the right side there is a blue scroll bar. You have to scroll it down to see the blue Global (DLM) ]}

[ Ignore if you are aware.
This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on Global (DLM), it may take up to 30 seconds, before the first page comes up.

Took 10 seconds just now using a medium speed DSL connection.
At the top of the PDF file is the page number box, to the right of the Down Arrow. When I refer to a page it is this box I refer to.

At the top header of the PDF file also, is the Zoom In icon ( + ), and the Zoom Out icon ( - )
Zoom In increases the view size.
Zoom Out decreases the view size ]

Do not know exactly, what the P numbers on the power supply cable connectors are, that you have. Do know the normal markings, but it may vary.

It DOES NOT matter however. I will show you photos of the power cables, and will guide you where they go.

Go to Page 13.
Look at the top right corner. ATXPWR1. (Can't see it clearly? Use the Zoom In icon)

1) This is for the 20-pin ATX main power cable, coming from the Power Supply.

This is an example of a 20-pin ATX main power cable, and it's respective connector on the motherboard,
(Note* Color DOES NOT matter. Color of the connectors can be ANY color ),

Probably marked as P1.
Now look at all three photos. In the middle photo you will see a Lock, on the side of the power cable connector.

It acts like a see-saw on a playground. You squeeze the top in, and the hooked end of it comes away from the connector.
Now look at the photo to the left.

The motherboard connector has a matching Tab, for the hooked end of the Lock, to go over.
When the power cable is correctly plugged in, and tightly, the hooked end will go over that tab.

2) 4-pin ATX +12 Volt power cable:
Look at page 13 again. Note where the Processor sits.
(Has a Fan on top of a finned Heatsink, which sits on top of the Processor )

Come down below the Processor, towards the Northbridge chip. It has a Heatsink sitting on it. It is placed as a diamond shape.
Look to the left of that diamond shape. You will see a small square socket, with 4 socket holes. (Probably white in color)

This is where the 4-pin ATX +12 Volt power cable plugs in. It also has a Lock on the power cable connector, and a matching Tab on the motherboard connector.

Can ONLY be installed in one direction, because of the Lock, and Tab, just like the 20-pin ATX main power cable.

This is an example of a 4-pin ATX +12 Volt power cable, and it's respective connector on the motherboard,

Probably marked as P4.

THAT, is it, for power cables that plug into the motherboard.

Do NOT know if you are using an IDE, or a SATA harddrive.
Will post for both.

A) IDE harddrive:
An IDE harddrive uses a 4-pin Peripheral power cable.
(Standard 4-pin Peripheral power cable, really. Explanation later)

Looks like this,

Note that the 4-pin Peripheral power cable example, is also shown plugged into an IDE harddrive. (EIDE)

May be marked as P2, P3, P5, P6, etc.
DOES NOT matter what P number it has, Luz.
As long as it looks like this, it will be FINE. Use any P number you want.

{ Note shape of connector. Has rounded corners on one side.
ONLY plugs in one way.
Note also that it has;
1 Red (5 Volts) wire, 1 Yellow (12 Volts) wire, and 2 Black wires.
(Ground wires. ALL Black wires are Ground wires}

B) SATA harddrive:
Uses a SATA power cable. Note that a SATA power cable has 15 contact pins. It is LONGER than the 7 pin SATA data cable.

Note that the inside shape is an L shape. ONLY lines up one way,

IF, you have a SATA harddrive, that has a provision for a 4-pin Peripheral power cable, AND a SATA power cable; ONLY use the SATA power cable!

DO NOT use both.

You will burn up the SATA harddrive. May not happen right away, but I assure you it will happen down the road.

This is what a SATA data cable's connector looks like,

Top photo. Again, color DOES NOT matter. Also note the L shape in the center of the connector. Both the power cable's connector, and the data cable's connector, have this L shape in the middle.
Goes over the L shape of the Harddrive's connectors.

[ SATA optical drive, (CD/DVD drive), also has an L shape for it's connector ]

IF you have a card reader it uses a Small 4-pin Peripheral power cable. Now you will see the difference, and why the other 4-pin Peripheral power cable is designated Standard,

Used to be used for a Floppy drive. Note the colors of the 4 wires.
Red, Yellow, and 2 Black wires.

Have more than one, and have a card reader? DOES NOT matter what the P number is. As long as it looks like this, you can use ANY of them.

For additional questions please post in a Comment.

{ Also, the first 4-pin Peripheral power cable connector, was made by Molex.
The name stuck. Molex power cable.
Ummmm, NO.
Kind of like the adjustable open-end wrench, being called a Crescent wrench }

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

God Bless You!!

I need to connect a new Antec 380d PSU to a A7v333 And connectors are different any suggestions?

The Antec 380D PS comes with an ATX 24-pin main power connector. If you look closely you'll see the extra 4-pin adapter is for motherboards that use all 24-pins. Your board needs only 20-pins. The extra 4-pin connector can be disconnected from the main cable & is not used.
Looking closely at the A7V333-X's main motherboard ATX power connector (On the board). The power connector has a locking tab on one side of the port. (This locking tab faces the memory).
This insures that you connect the power cable in one direction only. The Main power cable also has a locking tab attached to it and the two tabs lock together. See page 1-3, number 4.

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)

I can't find how to connect my dvd writer to the Asus Rampage II Extreme motherboard. The missed pin in the connection cable is in a different location

If you are trying to connect your DVD Writer using an IDE cable, then:
1. First, make sure that you are connecting the IDE cale in the correct direction. Make sure that the Red (or colored) wire in the cable aligns with pin 1 in the connector.
2. If the cable & connector are aligned correctly, then try to find a replacement IDE cable without a missed pin or with the missed pin in the correct position. This can cause no harm to neither the DVD Writer nor the motherboard.
