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:

The Molex connector looks like this:
http://assets.hardwarezone.com/2009/img/data/articles/2004/1215/tutorial-4pin_molex_power_conn.jpg

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

Now, if you have something that looks like this:
http://www.sierra-cables.com/Cables/images/SATA-Signal-Cable-1.jpg

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.

No spare molex power plugs for sound card in imedia s3810

No problem!

Use an adapter power cable, and have two 4-pin standard Peripheral power cables.

NOW, I hope your Power Supply will handle the additional load.
(It should. You just have to try it, and see)

Compressor will not engage on 2001 Impala? Where is low pressure switch located on 2001 Impala

It is located by the accumulator or dryer , a long canister shaped part, that will

have a pressure switch attached to it, and a two wire molex, if there is freon pressure

in the cannistor, the switch will close and send voltage to engage the clutch on

the compressor, if there is no voltage there the clutch will not work and you may

have a blown fuse or bad switch on your dashboard. i would check for voltage

at the pressure switch 1st, if its there, pull the molex off , jump it out and see if

the clutch engages. if you have power and you jump out the molex and the

clutch does not engage, you could have a bad clutch or bad compressor.

if it does engage, just replace the pressure switch, if you do replace it, make

sure to lube the seal with pag oil. good luck!

How 2 install a triple format sata internal drive in a gateway desk top

check for a open sata port on your computer. if there is one connect the hard drive with a SATA cable to the sata port on the motherboard.
connect the sata power to the hard drive or a molex to the hard drive if you do not have one. do not connect sata and molex to the hard drive together. if you don't have a molex connect you will need a molex to sata power adapter.
after connecting the hard drive to your pc. turn it on. in windows xp it will auto detect the hard drive and may prompt you to format the hard drive.

I am having several sata hdd what i noticed is the third connector on the drive 1data 2 power and3?

most SATA hard drives have both the molex and SATA power connectors to work with every PSU (power supply unit). There's a good chance that your third connector is the Molex one, don't worry about it.

Power Supply Types

There are two basic types of power supplies. There are AT power supplies, which are older and in older computers, and ATX power supplies, which you will find in virtually every new computer you can buy.

There are two fundamental differences between AT and ATX power supplies. First, the switch mechanism is different. AT power supplies use a normal on-off switch, which directly turns the power supply on or off.

ATX power supplies use a momentary switch which does not directly control the power. Instead, the switch signals the motherboard, which performs one of three actions:

If the computer is off, the power supply is turned on (which turns the computer on)
If the computer is on, the computer goes into power-saving mode (standby)
If the switch is held for more than 4 seconds, the power is cut and the computer turns off.

Because of this difference, ATX power supplies are better for projects that require the second power supply to turn on automatically when the computer is turned on.

The second difference is in the motherboard connector: AT power supplies provide two 6-pin connectors (figure 1), which are easy to insert backwards. The ATX connector is a single 20-pin connector that only plugs in one way (figure 2).

Figures 1 and 2: The difference between AT (left) and ATX (right) motherboard connectors.
Both power supplies provide two types connectors for plugging devices into. These connectors are called Molex connectors, and they come in two sizes (see figure 3 and 4). A power supply will generally have a few of each size.

Figures 3 and 4: Large (left) and small (right) Molex connectors.
There is no difference between the two sizes other than the size itself. Both sizes provide the same amount of power to whatever device is plugged into it (12V and 5V). The small Molex connectors are generally used only for floppy drives. Large Molex connectors power hard drives, CD/DVD drives, and many fans and lights as well.

Note: You can purchase large and small Y-adapters if you run out of Molex connectors. Be careful when using the Y-adapters however, because if your power supply does not have enough power for all the devices attached (especially true for older, lower-wattage supplies), you can damage it.

You can but a molex splitter so that you can plug the single molex you have into it and then have two, like a "Y". You will probably have to go online to a company like www.tigerdirect.com, www.newegg.com, or www.circuitcity.com who sell power supplys. I realize that means waiting a few days but the alternative is to either modify your PSU which voids the warranty or buy a different one. The splitter is inexpensive.

No power when press the button, power plug is good?

Good day sir/ma'am, chances are that your power supply box is the faulty part. But to make sure let us test your power supply box. here are the steps:

PC is off, open the side panels of the CPU, disconnect the 20(or 24) pin molex connector from the motherboard.
Get a piece of jumper wire, about 4 inches and splice the ends.
On the molex connector, locate the green wire, then using the jumper wire, short it with the black wire (there are lots of black wires there).
look at the exhaust fan, at this point it should be spinning (good). if not here are the other possible outcome: (1) the fan did not spin. replace the power supply box with a new one. (2) the fan spins momentarily then stops, this condition only occur once. Its either your power supply has no load (intermittent symptoms), or the switching controller stage part is faulty. Better buy a new one than have a headache. (3) blows a fuse. replace the entire box.

If you have a good power supply, install it on your CPU and test.

Use a jumper lead and shirt the green (power good) signal to a black wire (gnd) they are conveniently side by side. This will work on all power supplies regardless of wattage.
