Power connector for a L20WD800321 ? - Lorex L19wd804251 19 Lcd Dvr Surveillance System With 4 Weatherproof Cameras

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,

Well........................

The numbering for power supply cables, differs from one pre-built computer manufacturer, to the next.

GENERALLY, a P3 power cable is a 4-pin Peripheral power cable,

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

(Also misnomered as a 'Molex' power cable.
Molex came out with the design for the power cable CONNECTOR.
The name stuck. Kinda' like calling an adjustable open-end wrench, a 'Crescent wrench' )

A P4 power cable is usually a 4-pin ATX +12 Volt power cable,

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

This power cable was brought out to provide more power for the motherboard, and specifically the Processor. (CPU)
Does NOT connect to an optical drive. (CD/DVD drive)

DOES need to be connected to motherboard though, because it is POWER for the Processor!

Moving on.............

Let's dispense with the antiquated numbering of the power cables, and show you the real information you need;

There are two types of Optical Drives out there, currently being used;
1) IDE. Also known as PATA.

2) SATA

An IDE optical drive will use a 4-pin Peripheral power cable,

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

Note the rounded corners on top.
When plugging in one of these power cables, just always remember the rounded corners go on TOP.

The data cable used is a flat IDE ribbon cable. These are general examples,

Illustration,

http://en.wikipedia.org/wiki/File:Nappe.svg

Photo,

http://en.wikipedia.org/wiki/File:ATA_cables.jpg

I would like you to look at the connector end, and specifically the Locating Lug on one side of the connector,

http://en.wikipedia.org/wiki/File:PATA-cable.jpg

This style of Locating Lug consists of two small 'bars'.
There are types where it is filled in. Just one solid lug.

The Locating Lug lines up with a Cutout, on the optical drive.
(Or IDE/PATA harddrive)

IF, there is no Locating Lug on your IDE/PATA flat ribbon cable, post back in a Comment.
I will show you the proper way to connect it, using the Red stripe on the side of the cable.

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

If you have a SATA optical drive, it uses a SATA power cable.
This is a general example,

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

Between the SATA data cable connector, and the SATA power cable connector; the SATA power cable connector is the larger of the two.

SATA data cable connector has 7 contact pins.
SATA power cable connector has 15-pin.

This is an example of a SATA data cable, and it's respective connector,

http://en.wikipedia.org/wiki/File:SATA_ports.jpg

Note the L-shaped opening. The SATA power cable also has this L-shaped opening.

Observe the SATA data cable connector examples, on the motherboard.
Note the L shape.

(Note: The SATA data cable connectors on YOUR motherboard, may differ in style.
The ones shown (Red) are an Open design.
There are styles that are Enclosed. Have an oval around the
L shape)

To install the cable connector, line the L-shaped opening, with the L shape on the optical drive connector.

Tip: Turn this L over to the left, then turn upside down.
The small 'foot' of the L, always points DOWN, when installing connector.


The SATA data cable connector, that plugs into the optical drive, should be a 90 degree bent elbow.
The connector end that plugs into the motherboard, should be a Straight connector.

The SATA power cable connector, and the SATA data cable connector; MAY have a Lock on top.
Usually a small depression, or Tab, or 'bulb'.
Depress with your thumb tip, to install, or remove the cable.

(Hmmm, betting now the P3 power cable may be a SATA power cable.

How'd I do? Post back in a Comment)

For additional questions please post in a Comment.

Rob, Rob, Rob.............if I told you a thousand times, I............

Oh.......... where was I?

1) Power cables from Power Supply to motherboard:

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01237538&tmp_task=prodinfoCategory&cc=us&dlc=en&lc=en&product=3878557

A) 24-pin ATX main power cable;

Looking at the motherboard view the Right side. To the right of the Blue 39-pin IDE connector, is the 24-pin ATX main power cable connector, on the motherboard.

This is a general example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,

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

The power cable connector has a Lock on one side, and the motherboard connector has a matching Lock Tab.
When the power cable is deemed to be installed Correctly, and Properly; the Lock's hooked end is over the Lock Tab.

[Note* Color of connectors does NOT matter ]

B) 4-pin ATX +12 Volt power cable;

The processor socket is white in color. Around it is the black mounting ring.
The 4-pin ATX +12 Volt power cable connector on the motherboard, is to the Left/Bottom corner, of that black mounting ring.

Square, whitish (Opaque), and 4 socket holes.
This is a general example of a 4-pin ATX +12 Volt power cable; and it's respective connector on the motherboard,

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

2) Peripheral power cables from Power Supply;

A) The Harddrive is a SATA unit. Uses a SATA power cable,

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

B) The optical drive/s (CD/DVD drive) are also SATA units. They use a SATA power cable.

A SATA power cable's connector has 15 contact pins. Between it, and the SATA data cable, it has the longer connector.

Peripheral Data Cables;

This is a general example of a SATA data cable, it's connector, and a SATA connector on the motherboard,
(Note* Color does NOT matter),

http://en.wikipedia.org/wiki/File:SATA_ports.jpg

Here you can see the L-shaped opening of the connector, and matching L-shaped tab on the motherboard connector.

Most SATA power cable connectors, and SATA data cable connectors, have a lock. All you see is a 'bulb' type affair on top of the connector, that you squeeze down with a thumb tip.
Depress to remove, depress to install.

A 90 degree elbow connector for the SATA data cable, is used on the Harddrive, and optical drive. The straight connector end of the cable, plugs into the motherboard.

There are two SATA connectors on the motherboard. One White, one Black. One of them should have a SATA1 next to it.
(Or one will at least have SATA2 next to it)

SATA 1 connector is for the Harddrive. SATA 2 connector is for the optical drive.
The beauty of SATA is though, you can connect any SATA device, to any SATA connector on the motherboard; and BIOS will find it.

So it really doesn't matter what you plugged in where, as far as those two SATA headers are concerned.

3) Processor Fan cable, System Fan cable (Computer case fan);

Going back to the HP Support page above, and Motherboard Specifications; scroll down the list.
Click on the + sign to the left of the blue - Motherboard layout

Below the ATX12V1 connector is the System Fan connector.
(SYS_FAN)
This is where the computer case fan connects.
(ATX12V1 connector, is the 4-pin ATX +12 Volt power cable, connector)

Above the Ram Memory slots, and a little to the right; is the Processor Fan connector. Power to the fan. (CPU_FAN)

4) Front Panel audio connector, optical drive audio connector, Front Panel USB connectors;

Bottom edge of motherboard, from Left to Right;

Yellow connector is AUDIO1. Front Panel audio.
White connector is ATX_IN
For the audio cable from the optical drive.

Black connector (HD_AUDIO) is also for the Front Panel audio.

Don't know how they have the Front Panel audio, hooked up.
YOU will. The cable connectors to them are different from each other.

Front Panel USB connectors;
Further to the right are two white connectors. EACH one can support TWO USB ports.
One should be for the two USB ports in the Front Panel.
The other will go to a Card Reader in the Front Panel.

All the way to the right corner is the Front Panel header.
This is where the main wires from the Front Panel go.

Power On switch, Power On LED (light), and Harddrive activity LED (light)
The cable, and connector should match that 9-pin header.
If not here is an HP 9-pin Front Panel header - pinout,

http://h30434.www3.hp.com/t5/Desktop-Hardware/Getting-a-new-case-i-need-Front-Panel-pinout/td-p/842897

Scroll down to the photo, and pinout. (Dave G)

Under the Link and Resources heading, in the blue banner to the right, click on - Motherboard Manual

Page 32 of the PDF file. Page 2-10 for the manuals actual page,

2-7 Connector definitions:
Power Connectors

"A 24-pin main power supply connector (JWP1), and three 8-pin CPU PWR connectors (JWP2 / JWP3 /JWP4) on the motherboard.
These power connectors meet the SSI EPS 12V (Volt) specification.

In addition to the 24-pin ATX power connector, the 12V 8-pin CPU connectors at JWP2 / JWP3 / JWP4, MUST be connected to your power supply.

Warning: To prevent damage to the power supply or motherboard, please use a power supply that contains a 24-pin and three 8-pin
power connectors.

Be sure to connect these connectors to the 24-pin (JPW1) and the three 8-pin (JPW2,JPW3 and JPW4) power connectors on the motherboard.

Failure in doing so will void the manufacturer warranty on your power supply and motherboard."

So there you have it.

YES.

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)

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.

Use "archive" on the remote. Enter the admin password. Takes some playing around in there to really figure it out, but that's where you start.

It's a Small Form Factor power supply.
4.9 inches Wide, 2.5 inches Tall, and 3.9 inches Long.

Put's out a maximum of 150 watts, (Supposedly)
Has the following power cables;

A) (1) 20-pin ATX main power cable:
http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

The main power cable. Main power cable designs have moved up to the 24-pin design, with some main power cable connectors having a 20-pin connector, and a separate 4-pin connector

B) (1) 4-pin ATX +12 Volt power cable:
http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

This power cable is power for Intel Pentium 4 processors,and on up.
I have a eMachines T-1090 in my shop. (Still works great) It has a Pentium III 933MHz processor. Didn't know Pentium 4's were offered.

C) (4) 4-pin Peripheral power cables.

(The connector on the end of the power cable, is referred to as a standard 4-pin Molex connector. This is a misnomer. Molex was/is, a company that made this style of connector first. The name Molex was on the connector. The name stuck with people. It's just like referring to an open end adjustable wrench, as a Crescent Wrench)

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

D) (1) Floppy Drive power cable

Except for the size, and shape of this power supply, just about any low-end ATX power supply with a 4-pin +12 Volt power cable, would work.

More in additional comment.

The connector is special to Dell, and not generally available. You may need to purchase a new power supply. The connector has 3 concentric terminals, and one is used to 'ID' the power supply as genuine DELL. A plain DC connector can be used, but the batterys will not charge.

Hi there
The front panel connectors are mainly,

• harddisk activity connector
• power switch connector
• reset switch connector
• power LED connector
• speakers connector
• USB connector

Harddisk activity connector
This normally comes red in colour and is labeled as HDD-LED
Power switch connector
This comes green in colour and is labeled as POWER-SW
Reset switch connector
This usually comes grey in colour and is labeled as RST-SW
Power LED connector
This is usually green in colour and is labled as PWR-LED
Speakers connector
This speaker will give different beep sounds during boot to tell the user if there is any errors. It occupies 4 pins, however only 2 is important for the function. Be sure to connect the red coloured cable to the positive polarity and the black to the negative.
Front panel connectors pins on the motherboard
Front panel connectors from the casing

Good luck and thanks for using FixYa!!
