Replacing DVD/CD drive

Look inside of your tower, you will have a few different cords connecting to your DVD/CD drive.

It should either have a 4 pin Molex connector and an IDE or a Sata connector and power.

The IDE cable looks like this:$OD%2DLarge$

The Molex connector looks like this:

IDE is an older tech that uses a 4 pin molex to connect it.

Now, if you have something that looks like this:

It uses Sata, and the power cable looks like it as well, it's just longer.

To make sure the DVD drive you're working will work with the current DVD/CD's you have, just look on the front of the CD you are going to use, in truth it usually should work with anything. It's even RW so you can re-write data to RW CD/DVD types.

Pretty much, just make sure that it uses the same power type and data connector as your current one. Power type being the 4pin molex or the Sata power plug. Data type being the IDE cable or the Sata cable.

If it matches, it will work :) I hope this helps.

How to connect your hard drive to your motherboard The first thing you have to...

How to connect your hard drive to your motherboard

The first thing you have to figure out is what type of hard drive you have, a PATA or a SATA drive.

PATA = Parallel ATA
This type of drive uses the older IDE connections. Most of your current motherboards still have aleast one IDE connection to support the ROM drives on the market that have not moved over to SATA connections but you can still connect a hard drive to this connection if needed. The thing to keep in mind is that you can only connect 2 IDE devices to one IDE connection on the motherboard.

Here is an example of an IDE cable. If you can see there are tabs on the cable to make sure you line up the pins properly.

SATA = Serial Advanced Technology Attachment
This type is now the standard that most hard drives are. Also note that alot of your ROM drives are switching over to this format as well.

Here is an example of a SATA cable.

In regards to power connectors If you are using a PATA drive then you will use the Molex power connector. Note some of the early SATA drives use this power connector as well.

For the SATA drives you would use the SATA power connector. Note if your power supply does not have this connection you can get an adapter that goes from a Molex connection to the SATA connector.

Next you will need to find the connectors for the hard drive on your motherboard. Below if pictures of the 2 connection types.

P3 DVD connector


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,

(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,

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.


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

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,



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

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.

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

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,

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)

This is my first build and all the connections are a bit confussing need picts of how to install cables to hardware

The following picture will definitely help you to install new power supply.
The 4 pin CPU power connector is using in most of the desktop motherboard. If your motherboard is gaming type or workstation board you need to connect 8pin CPU power connector. Molex connectors are using to power up DVD Drives and HDDs. In New model power supply instead of molex connector SATA Power connectors are coming.

Hook up fro WD3200 SATA hard drive. I am trying a new power supply and I dont remember how the harddrive was connected ,DoH Do I need both the SATA and the 4 pin molex connectors connected ?

You cannot use a molex connector on a SATA hard drive. You need to connect one of the black plugs from your power supply and the SATA (red) cable from *********** board.

How do I install a new CD drive in an old destop computer It is an old Compaq Presario 5WV254 The existing CD drive has a ribbon type connector that mates up to the pins on the drive plus a 4 pin module...

The Compaq Presario SWV254 Desktop PC uses IDE technology, not SATA.
In the specifications for the above Desktop PC, it states ATAPI is used for the interface technology, and connector, for the optical drive/s.

[IDE is also referred to as PATA. Parallel ATA
SATA is Serial ATA.
The PATA designation was implemented, so that computer users could easily distinct between IDE, and SATA technology]

1) The IDE interface cable, (Flat ribbon cable), has a connector on each end with 40 socket holes.
(39 are actually used. Most of the time, one socket hole is blocked off. (Pin 32)

2) The SATA interface cable has 7 contact pins. Also referred to as a Data cable.

3) The IDE devices, (Harddrive and optical drive), use a 4-pin Molex connector for the power cable.

4) The SATA devices use a 15-pin connector on the end of the power cable.

More info on SATA,

The Samsung SH223C optical drive is a SATA device.
You cannot just plug it in.

IF, you have an open, (Available), PCI slot on the motherboard, you can use a SATA adapter card.
The SATA adapter card plugs into the PCI slot, and has the necessary connections on the card, for a SATA interface cable.

Just for the SATA interface cable. Does not have a connection for the SATA power cable, you need.

You have to buy a 4-pin Molex to SATA power cable adapter, and connect it to an available 4-pin Molex power cable, on your power supply.

You will also need a SATA data cable. The interface cable that goes from the SATA adapter card, to the SATA optical drive you're trying to install)

This is an example of a SATA adapter card. It is not an advertisement for said website, nor manufacturer,

How do i install dvd rewriter with windows 7. There are different conections at the rear of the factory fit DVD...?

You generally only need 2 connections for an optical drive to work: Data and Power. Data will be either IDE (long 40 pin ribbon cable) or SATA (small [~1/2"] 'L' shaped connection for a much thinner ribbon cable).
Power will be either Molex (4-pin connector with red, black, black, yellow wires) or a SATA power connector that looks like a larger version of the SATA data connector).

All other connections are not needed, such as the small 4 pin audio connection which usually hooks up to the motherboard or sound card, but is only needed for analog playback of audio disks.

Hooking up a Liteon 24X DVDrw burner

The SATA drive is to be used with a motherboard that supports SATA 1 or 2.
If you have a board that supports SATA, you should also have a power supply that supports SATA.
The 7 pin connector is for data. the other connector is for power.
Hope this has helped you.
P.S. Their are conversion kits for the power supply if yours does not support SATA but your board is something else all together.
Get back to me with the make a model number of the PC and I will check if you want.
