DX4820 power supply

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.

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.

[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.

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',

E) Needs one 4-pin (Small) Peripheral power cable, for the Card Reader.

Also needs 300 Watts.
A Power Supply like this one would work,

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.

1 Answer


During the boot up process are there any beeps? If so how many short or long? 1 short beep is typical of a normal boot indicating no conflicts. What you can also do is unplug or remove any unnecessary peripherals (i.e. Hard drive, cd drive, any expansion cards) So that all you have is the the power supply, monitor cable, motherboard, cpu, and memory plugged in and attempt to boot. If this is successful add one peripheral at a time and boot again untill the boot fails again. This will usually indicate a problem with the power supply, either its faulty or not providing enough wattage to support all the peripherals, otherwise its a conflict with the specific peripheral that causes the failure. IF none of that works attempt to reseat all your connections, cpu socket, memory socket, power supply, and video cable. If all that still fails it is most likely a bad motherboard, its not unheard of to receive a DOA motherboard. As a last ditch attempt you can determine is a faulty video chip or the motherboard itself by installing a pci video card and seeing if its successfully boots.

Atx motherboard wiring diagram

For the power cables from the Power Supply? Or Power Supply, and Front Panel header on the motherboard?

For both of these you need to state the computer manufacturer name, and Model Number.
Post back in a Comment.

If you just wish a generic, one-size-fits-all explanation;

A) 20 or 24-pin ATX main power cable.

The older computers use a 20-pin ATX main power cable. As computers needed more power to the motherboard, the 24-pin ATX main power cable was brought out,

Scroll the page down for info on the 24-pin ATX main power cable.

[ Much older motherboards (AT) used two main power cables. { In the link - Original PC main power cables} ]

B) 4-pin ATX +12 Volt power cable.
Was brought out because Processors needed more power, than the 24-pin ATX main power cable feeding the motherboard, could deliver.

Power for the Processor,

C) 4-pin standard Peripheral power cable
Commonly misnomered as 'Molex'.

Molex was a model name given by the first manufacturer, of this design of power cable connector.
The name stuck. Kind of like referring to an adjustable open-end wrench as a Crescent wrench.

It is also referred to as a 4-pin Standard Peripheral power cable, because there are two styles of 4-pin Peripheral power cables.

4-pin Standard Peripheral power cable,

Generally used for IDE (PATA) harddrives, and IDE optical drives.

4-pin Small Peripheral power cable,

Older computers used it for power to the Floppy Drive. It's generally used now to provide power for a Card Reader.

Note that both types of connectors use the same power wires, and 2 ground wires.
Yellow is 12 Volts
Red is 5 Volts
Black is Ground

[ Also, in the ATX main power cable:
Orange is 3.3 Volts, the Green wire is the Soft Power On wire. Abbreviated as PS_ON.

Power Supply plugged into power, the Soft Power On wire is briefly touched to ANY Ground wire. This is bypassing the Power On switch.
If the computer (Power Supply) comes on, you have a bad Power On switch.
IF the computer (Power Supply) does NOT come on, you have a bad Power Supply ]

(ALL Black wires are Ground wires. They all lead back to one central Ground point.
ALL power wires lead back to one point in the power supply, for EACH power wire.

The 12 Volt power wires, (Yellow), all lead back to one point in the Power Supply.
This is the 12 Volt power rail.

The 5 Volt power wires, (Red), all lead back to one point in the Power Supply.
This is the 5 Volt power rail.

The 3.3 Volt power wires, (Orange), all lead back to one point in the Power Supply.
This is the 3.3 Volt power rail ]

D) SATA power cable
15-pin power cable for SATA harddrives, and SATA optical drives,

[ The smaller 7-pin SATA connector is the interface cable, or data cable.

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

It will burn out the harddrive if you use both. It may not do it right away, but eventually it will.
I have had people state over the years, that they were using both power cables. Came back two months later to tell me their harddrives had burned out ]

Is there a schematic somewhere that shows how to plug these things in? I may be short a cord Thanks! Jack

First thing to plug in are the Power Supply cables.

The main one to start with is the ATX main power cable.
There are two main variations of the ATX main power cable.

The 20-pin ATX main power cable,

,and the 24-pin ATX main power cable,

The 20-pin version was used on the older model computers. It was found that more power was needed to the motherboard due to newer computer components, and four extra power wires were added.

In the center photo note the lock on the side of the connector. It operates in a see-saw fashion. The top is squeezed in, to release the hook of the lock from a tab on the female connector, on the motherboard. Then the male connector can be removed from the connector on the motherboard.

Depending on the motherboard you may also have a 4-pin ATX +12 volt power cable. This is additional power to the motherboard, and is mostly used to provide additional power to a Processor.

Note the lock on the side of the connector. It operates in the same fashion as the ATX main power cable's connector.

Peripheral devices inside the computer also require a power cable.
If you have an IDE, (Also known as PATA), harddrive it will require a 4-pin standard Peripheral power cable.
Commonly misnomered as a Molex power cable,

This power cable is also used on IDE type optical drives. CD or DVD.
It can also be used along with an adapter cable to power a computer case fan.
There is no lock, but there is only one direction the cable will plug in.
There are two rounded corners on one side of the plug to line it up.

On all power cables use the connector itself to unplug the cable, Not the wires!

(Sometimes unplugging a 4-pin standard Peripheral power cable is tough.
The connector is rocked side to side while removing.
Sometimes an additional tool is needed to EASE the connector out.
In all cases make sure the computer is unplugged from power BEFORE working on it, and assure that you are following Anti-Static Precautions)

You may have a SATA harddrive, and also you may have SATA optical drives. (CD or DVD drive)
They use a SATA power cable.
The SATA power cable has 15 pins.

[Note a SATA data cable has 7 pins. It is the shorter of the two cable connectors]

IF you have a SATA harddrive that has provisions on the back of the unit, to plug BOTH a SATA power cable, and a standard 4-pin Peripheral power cable, ONLY use the SATA power cable!

Using both power cables will burn out the harddrive.
Sometimes it doesn't happen right away, but it eventually will.

The last power cable I will mention here is the 4-pin small Peripheral power cable.
On older computers this power cable was used on a Floppy Drive.
Now more used to provide power for a Card Reader.

If you "popped" the power supply, I would check to see if the RAM might have taken a hit as well. Ram chips and CPU are sensitive when it comes to power surges. I would troubleshoot the system, unplug everything. you need monitor, power, cpu, and ram (1 at a time). Check to see if the system will POST. if you do get it to POST, start with 1 item at a time and see if the system will POST every time. If nothing happens, there is a chance you may have a damaged motherboard or cpu.

How do I replace the power supply?

To install a new power supply, you don't have to send your computer to a specialist; you can install one yourself.
Before You Purchase. You can buy a new power supply from your computer's manufacturer, a computer store, or an independent manufacturer, but first you should examine your current power supply. Check to see if your power supply is AT (Advanced Technology) or ATX (Advanced Technology Extended) style. Your power supply should be labeled AT or ATX, and in the same area, you should see the output voltage in watts (for instance, ATX-250W). Be sure to buy a new power supply with the same or higher wattage as your old power supply. The higher the wattage, the more energy your power supply will provide to your computer. If you're adding additional components to your PC, you should purchase a higher wattage power supply. Furthermore, measure the dimensions of your old power supply, and make sure these measurements are the same as the new power supply you're going to purchase.

Get Started. To replace your old power supply, you'll need a Phillips or flathead screwdriver, a well-lit, low-static area (avoid carpeted areas), small containers (to hold screws or loose parts), and a pen and paper.

Turn off your computer and all the peripherals (such as your monitor, printer, modem, and scanner). Unplug your PC and all the peripherals from their outlets. After that, unplug all peripherals from the back of the computer. Move to a well-lit, static-free area, such as a tile floor or a kitchen table. Remove the computer case or panels to expose the interior of your PC. The power supply is enclosed in a metal box located in the corner of your computer case.

Before you disconnect any wires, be sure to sketch and/or note where and how each of the wires is connected. These notes will help you remember where to plug things in when you install your new power supply. In addition, when you remove any components from your PC, you should put any loose screws or loose parts in separate, labeled containers to keep them safe and organized.

Find the bundle of wires that come out of your power supply. These wires connect to your motherboard and various drives. Follow the wires to their white, plastic connectors and pull each connector until it is free (never pull directly on the wires). Remove all wires from their internal components. You may have to disconnect the on/off switch if the switch is not built onto the power supply. Occasionally, a large bracket secures a computer's power supply. To remove the bracket, loosen the screws and take it out. Now, remove the four screws closest to the outside edge of the computer case. Don't remove the screws that hold in the power supply fan. Carefully lift out your power supply (don't be afraid to pull it out with a little force).

To install your new power supply, you can reverse the actions you took to remove your old one. Put the new power supply in the same place as the old unit, tighten the perimeter screws into place, replace the bracket, and reconnect the on/off switch. Reconnect the wires by following your sketches and/or notes in reverse. If you have any loose wires, bind them together with a twist-tie. Make sure the voltage switch visible on the power supply is set at 120V (120 volts, common in the United States). Replace your computer case/panels. Connect all peripherals and the power cord to the back of your PC. Plug your PC and the peripherals into their respective outlets.

Start It Up. Turn on your computer and monitor. You should hear the normal sounds of a computer powering up, such as the fan and hard drive spinning. If your PC doesn't turn on or if any components in your system don't function, you should turn off your PC and unplug it. Remove the case and check to make sure all the wires are properly connected. Replace the case, plug in your computer, and turn it back on. If you continue to experience problems, contact the power supply's manufacturer or your PC's manufacturer.
