Hi t aforrester

I am a bit unclear as to what exactly you are looking for. Are you looking for instructions on how to attach your power supply to your motherboard or info on the circuit diagram of the power supply itself?

Kind Regards

    At this link you can get many details about wiring the power supply at the motherboard and the other peripherals. In case you need the power supply schematic diagram there isn't available. Also I have to tell you that your power supply is not suggested by me (personal opinion) to use at a pc, because it hasn't enough power efficiency for the nowadays systems. Since most of the problems comes from the power supply, I suggest you a more reliable one. The wattage of the power supply is calculated by the total average / peak power ratings of the system (icluding cpu, chipset, hard disks, cd/dvd roms, fans etc)

    In case of a problem or clarification, don't hesitate to post me a reply before rejecting my answer.
    If you are satisfied, accept my solution.

    Thanks and regards

I getting loud annoying sounds from my CODEGEN ATX2 switching power supply I think its the fan should i replace the power supply and is it affordable to have it done?


Yes you should replace the power supply and you can do it yourself go to the back of the tower and at the top you will be able to see the power supply it is held in with 3 to 4 screws open the side panel and unplug all the wires that go from the power supply to the different components of the computer
then unscrew the power supply from the back of the tower and lift it out you will need to get a ATX
P4 power supply you can get the best price at new Egg ,or Amazon .com the prices very in price from 30.00 to a Hundred or more

My power went out and when it came back on the computer would not come on


eMachines uses low quality hardware components inside their computers. This is the way they can sell them at budget prices.

One main hardware component is the low quality power supply they use.
A generic power supply made by Bestec. (A generic power supply manufacturer)

(PSU. Power Supply Unit. The type of PSU used is a SMPS.
Switched-Mode Power Supply,

http://en.wikipedia.org/wiki/Switched-mode_power_supply )

Low quality;
A) Electrolytic Capacitors (Radial Aluminum Electrolytic Capacitor)
B) Rectifier Bridge
C) MOSFET/s
D) Wiring is too small in gauge
to name a few of the components.

However IMHO it is also best to check out the Power On switch.
There is a simple test to see whether the problem is a faulty Power On switch, or a faulty Power Supply.

The test involves bypassing the Power On switch. The Power On switch is not involved in this test.
A jumper wire is used on the Soft Power On wire, [ PS-ON ], and a Ground wire in the ATX main power cable connector.

If you bypass, and the Power Supply comes on you have a bad Power On switch.
If the Power Supply does Not come on you have a bad Power Supply.
If you would like to know more in detail on how to perform this simple test, simply post so in a Comment.

The Power Supply used is just a common ATX version.
ATX refers to the Form Factor of the power supply.
Regular size ATX form factor is approximately 6 inches Wide, 5-1/2 inches Long, and 3-1/2 inches Tall. (Height)

There are also differences in the pinout of the ATX main power cable.
Yours may have 20-pins, or 24-pins.
Power Supply's sold now take this into consideration.
Their ATX main power cable can be used as a 20-pin, or a 24-pin version.

[ General example of a 20-pin ATX main power cable, and it's connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

Example of a 24-pin ATX main power cable, and it's connector,

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

Your motherboard may also require an additional power cable, commonly referred to as a P4 power cable, or P4 ATX 12V power cable, or just ATX 12V.
The actual name is 4-pin ATX +12 Volt power cable,

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

If you would like help in finding an inexpensive reliable Power Supply, please post in a Comment.
I will need to know what Model Number of eMachine you have. It's on the back next to the Windows product key, or up on the side of the computer tower.

If you need anything explained that I have stated here, please let me know in a Comment.

I have presently a atx 350w power supply would yours solve my supply problem


If your ATX switch mode power supply is faulty then I suggest you replace it with a new one that is 350 watt or higher wattage.
Fixing faulty ATX power supplies is not a DIY project, there are dangerous voltages in these power supplies and can cause death or serious injuries.

I am looking at a Dell Dimension 4550 PC for a friend and it won't boot up...i push the power button on and there is an almost orange/greenish light on the power button... no beeps no diagnostic lights are...


Bad Power Supply. Weak voltage power rail.

[There are three main voltages produced by the Dimension 4550's Power Supply.
1) 3.3 Volts
2) 5 Volts
3) 12 Volts ]

The Power On button LED functions as a diagnostic light also.

Dell Support > Dimension 4550 > Service Manual,

http://support.dell.com/support/edocs/systems/dim4550/

Left-click on Solving Problems, then click on Power Problems

The Power Supply is just an ATX form factor version. The common Power Supply form factor used in MANY desktop computers.
(ATX form factor for a Power Supply refers to the size, and shape of the Power Supply's case.
Approximately 6 inches Wide, 5.5 inches Long, and 3-1/2 inches Tall)

HOWEVER, (Not shouting), there is an area of concern, should you try a Power Supply you may have available for a test, or purchase one.

It involves the wiring of the 20-pin ATX main power cable. More specifically the power cable's connector.

To explain view the standard wiring, set for a 20-pin ATX main power cable's connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

Looking at the photo to the far right, observe the color code of the wires, going down into the socket holes of the connector.

Look at the Lock tab on the side of the connector. This will help you orient the color code of the wires, and their placement in the socket holes, to the chart below the photos.

The connector on the end of the 20-pin ATX main power cable, is a Male connector.
Where the wires go into the connector, is the Back of the connector.
In the middle photo you can see the Front of the connector.

The wires going down into the ATX main power cable's connector, end in a female metal terminal.
The connector on the motherboard, (Shown in the photo to the Left), has Pins.
The metal female terminals go over the Pins.

The pins are numbered. The color code of the wires match up to the pins.
This is shown in the chart.

Now look at Dell Support > Dimension 4550 > Technical Overview > DC Power Connectors >
DC Power Connector P1

http://support.dell.com/support/edocs/systems/dim4550/techov.htm#1101897

The illustration may not be accurate. You'll have to compare since you have the computer, and Power Supply in front of you.

For a time period Dell was a Proprietary manufacturer.
Meaning they wanted THEIR parts used on THEIR computers, and ONLY THEIR parts.
They had the motherboard manufacturers make motherboards according to their specs.

One of the specifications was that the pins would be CHANGED around, in the motherboard connector for the ATX main power cable.

They also had Power Supply manufacturers make the ATX power cable to their specifications.

This means if a user bought an aftermarket Power Supply, the color code of the wires in the ATX main power cable would Not match.

Many users did buy an aftermarket Power Supply, and installed it.
Burnt motherboards, fried Processors, and graphics cards, resulted.

Orange wires are 3.3 Volts
Red wires are 5 Volts
Yellow wires are 12 Volts.
Black wires are Ground wires.

Guess what happens when you plug a 12 Volt wire into where a 3.3 Volt, or 5 Volt, or Ground wire is supposed to Be?
POOF!

My suggestion would be to look for a Power Supply that is an ATX form factor, is KNOWN to be good, and is compatible, for a test unit.
You, or someone you know may have upgraded to a better computer, and you may be able to borrow the Power Supply for a test unit.

Compatible:
Has the Correct power cables.
1) 20-pin ATX main power cable, OR a 20/24-pin ATX main power cable.
(20-pin connector that has an additional connector with 4 pins. Just use the 20-pin)

2) 4-pin ATX +12 Volt power cable. (Also referred to as P4 MB, and P4 ATX 12V)

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

(Power for the Processor)

3) Enough standard 4-pin Peripheral power cables.
(Misnomered as Molex)

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

(Power for the IDE Harddrive, and Optical drive/s)

Also:
You can change the power wires around in the ATX main power cable's connector.
Change them around, in an aftermarket Power Supply's ATX main power cable's connector.

Missing power supply. First, thanks to fredtmccoyjr for the boot fix. the BIOS update from A06 to A09 actually allows me to enable boot from harddisk in the settings, instead of settign a useless tick on...


It was the 1996 to 2000 time frame, that Dell was proprietary with the 20-pin ATX main power cable, and the matching connector on the mobo. (MOtherBOard).

Standard 20-pin ATX main power cable, and it's corresponding connector should work, then add the 4 power wires that are missing, in a separate connector.

To expound:

View this standard 20-pin ATX main power cable, and it's respective connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

The power wires should be in the same place as your P3 units.

(Match the color codes.
Use the lock tab on the 20-pin ATX main power cable connector, to base where the pins are.

Pins 1 though 20. Match the color code of the wires to the pins, and use the chart to compare)

Here is a view of a standard 24-pin ATX main power cable, and it's respective connector, so you can see what power wires are missing, from the 20-pin ATX main power cable connector, that are present in the 24-pin ATX main power cable connector.

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

Note the missing power wires, and what pins they line up with.

The P4, or also stated as the 4-pin ATX +12 Volt power cable, uses two Yellow (12 Volt) wires, and two Black wires, (Ground)

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

Since you don't have the male connector, be sure to orient in your mind where the Yellow (12 Volt) wires go, and the Black (Ground) wires go, by looking at the lock tab on the side of the female connector, on the motherboard, and comparing it to the photo.

Transfer this info, to the P4 connector you are going to make.

Where to get the power wires you need? Connect to any extra 4-pin Peripheral power cable wires, or splice off of ones that are in use, is one suggestion.

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

The links given are near the middle of the page. Scroll back to the top. Left-click on any power cable connector, that you wish more information on.

More info,

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

Scroll to the bottom of the page, and look at the chart under the heading -

24-pin ATX12V 2.x power supply connector
(20-pin omits the last four: 11, 12, 23, and 24)
