Gateway Intel 850 Socket 478 ATX Motherboard Power Supply

I am crazy I know, But I need to find out what wires need to be hooked up to what pins on the "aux power connector" so I can finish making my noncompattable power supply work on this motherboard. I am aware that this is stupid and dangerous but I am on a pc with a jerry-rigged power supply now that has worked fine and I am having a blast! I hope someone will help me further my reckless tinkering.

    Well, first of all, I need to know what type of power supply you are using, and what type of motherboard you want to use. What kind of incompatibility they have, so I get a picture of what is fit, and what is the gap. Please share with us here.

Please use the following as a reference: ATX12V Power Supply Design Guide, http://www.formfactors.org/developer/specs/ATX12V_PSDG_2_2_public_br2.pdf

Sections 4.5.2 and 4.5.3 (Page 38) list the signal and wire colors for the +12V2DC (2x2 pin) and Peripheral (Molex) Connectors. Figure 11 (page 36) shows diagrams of the connectors and pin-outs for reference.

Most likely, you are looking for the 2x2 pin connector; pins 1&2 are common (black wire), pins 3&4 are +12V2DC (yellow wire w/black stripe)

Where to find manual for motherboard 143159 imperial Gv 20030812?


Good luck. Used to be you could get a mobo manual from e4allupgraders.

The Imperial board is made by TriGem
Started out as TriGem Sambo, is now TG Sambo

The Imperial models were Imperial G, Imperial GL, Imperial GV, and Imperial GLVE, if memory serves.

TriGem Imperial GV - 143159 -20030812

http://www.ebay.com/itm/gateway-emachine-mother-board-imperial-gv-20030812-/111025938736?pt=Motherboards&hash=item19d9a96130

Bad photo, but it does have the mouse Zoom In feature.

CMOS jumper and Clear BIOS Password jumper, down by the Front Panel header; is the same as used on the TriGem Imperial GLVE -129504,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph07540&lc=en&cc=us&product=83481

Scroll down to Motherboard Layout (Illustration), and Photo; then down to jumper info.

(By the way.........the BIOS chipset is removable, therefore replaceable)

The front of your computer is the Front Panel.

The area of contact pins on the motherboard, that the Main wires from the Front Panel go to; is the Front Panel header.

This is PANEL in the illustration. Bottom/Right corner. Uses the same Front Panel pinout, as your Imperial GV uses.

8 pins along in a row.
Starting on the LEFT side going towards the Right;
Pins 1, 2, 3, NO pin 4, 5, 6, 7, and 8.

A) Pin 1 is N/C. Not Connected
(May not even be there for all I know)

B) Pins 2 and 3 are for the Power On LED.
Pin 3 is for the Positive wire.
If the PWR LED is dim when the computer is on, switch the wires around.

C) There is NO Pin 4. At least that is what I make, looking at the Front Panel header pinout. Indicate Pin 1 is N/C, and Pin 4 is N/C.

D) Pins 5 and 6 are for the HarDDrive activity LED light.
Pin 5 is for the Positive ( + ) wire.
If the HDD LED is dim when the Harddrive is active, switch the wires around.

E) Pins 7 and 8 are for the Power On switch.

HOWEVER, since the motherboard photo on HP Support, and Ebay; is as clear as mud; suggest you do this,

Connect your Power On switch to Pins 7 and 8;
OR,
touch across them briefly with a small flat tip screwdriver.
(Power plugged in)

See if that is correct for the Power On switch. What will happen if it isn't? Nothing. Pressing the Power On button just won't turn the computer on; is all.

Turned the Power Supply (Computer) on?
Good. We can assume the rest of the pinout is correct also.
Want to make sure? Easy.

Take an LED bulb (Power On, or HDD), and touch it's two wires to the Power On LED pins, in the Front panel header.
Stays on? Yep. Power On LED pins.

Blinks? Whoops.
Those are the Harddrive activity LED pins.
Just that easy to check it. With using an LED, you won't harm anything even if the pinout is wrong.

Moving on.........

Using the HP Support page, for that TriGem Imperial GLVE motherboard, the Motherboard Layout is the same as the Imperial GV.
(So is photo, 'natch)

Referring to the layout, and photo;

A) Power cables:
Two
20-pin ATX main power cable, and 4-pin ATX +12 Volt power cable.

General example of a 20-pin ATX main power cable, and it's respective connector on the motherboard,

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

Note* Color of power cable connector does NOT matter.
Can be Whitish, Yellowish, Black, Sea Foam Blue, or Lactating Mammary Gland Pink. (Made the last two up)

Goes to the motherboard connector immediately above PCI slot 1.
Note the LOCK on the side of the power cable, and corresponding TAB on the motherboard connector.

General example of 4-pin ATX +12 Volt power cable, and connector on motherboard,

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

Power for the Processor
Looking at the motherboard illustration, look at the Northbridge chip; -> Intel 845GL in the middle.

ATX 12V to the left, is where the 4-pin ATX +12 Volt power cable plugs in.
See the aluminum finned Heatsink, sitting on the Northbridge chip?
The whitish/yellowish 4-socket hole square connector, to the Left.

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

See where it states Primary IDE to the bottom/right in the illustration? Blue IDE connector?
That is where the Harddrive plugs in.

This is a general example of the connector,

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

Note the Locating Lug on the top/middle. This particular style uses two ribs. Some are just a solid block.

The reason I brought it up, is if there is NO Locating Lug on the connector; let me know in a Comment.
I'll tell you how to use the faint Red stripe, on the side of the flat cable; in order to plug it in correctly.

The optical drive (CD/DVD drive) plugs into Secondary IDE.
You can see where a Floppy Drive plugs in.

Above the Processor (CPU) socket to the Right, is where a computer case fan plugs in. PS_FAN.
To the upper Left, is where the Processor fan plugs in.
CPU_FAN

To the left of the ATX Power Connector, (20-pin ATX main power cable; motherboard connector), is the connector for the small audio cable; coming from the optical drive. (CD/DVD drive)

Optical Drive In.

Right next to the round CMOS battery, is the Front Panel USB header.
-> TWO USB ports connect to this header.
(USB)

A 4-pin Peripheral power cable is used for the Harddrive, and Optical Drive.
Misnomered as 'Molex' power cable,

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

Note the rounded corners. When plugging the power cable in, these rounded corners always go UP.

[Molex was the first maker of the power cable connector.
The name stuck.
Kind of like calling an adjustable open-end wrench a 'Crescent wrench' ]

The motherboard chipset is an Intel 845GV.
This is what Processors (CPU), and Ram Memory are supported,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Pentium_4_chipsets

Single-Core processors.
Use a Socket 478 processor socket.
Intel Pentium 4, Celeron, or Celeron D.
(Celeron D is NOT a dual core processor)

400 to 533MegaHertz Front Side Bus processor support.
(400/533MHz FSB)

DDR Sdram ram memory that is either 266MegaHertz, or 333MHz.
(PC2100 and PC2700, respectively)

2GB's of it.
1GB for EACH ram memory slot.

For additional questions please post in a Comment.

I triger power switch but dose not work mother board


Check to see if the problem is the Power On switch, or the Power Supply.
Bypass the Power On switch.

http://www.supermicro.com/products/motherboard/Xeon/GC-LE/P4DL6.cfm

[For the motherboard user manual;
Go to the heading, to the upper right in blue - Links and Resources.
{Don't believe we can use the Ampersand on here. Let's try & }

In the list below it click on - Motherboard Manual
Click on the blue - [ Download ] for the second file listed.
MNL - 0660 (English)
P4DL6 / P4DLR / P4DLR+ ]


The SuperMicro P4DL6 motherboard can use a 20-pin ATX main power cable, OR a 24-pin ATX main power cable.

Suggest you use a Power Supply, that has a 24-pin ATX main power cable.
Why?
A 20-pin ATX main power cable, does NOT provide enough power to the motherboard.

General example of a 20-pin ATX main power cable, and it's respective connector on the motherboard,

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

[NOTE*
Color of the connectors does NOT matter ]

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

Note the additional power wires.
3.3 Volts (Orange), 5 Volts (Red) { 2 of them }, and a Ground wire. (Black)

Which type of ATX main power cable are you using? Don't know. You haven't stated it.

For both,....look at the Green wire. This is the Soft Power On wire.
(Abbreviated as PS_ON)
A jumper wire is used to jump from the Green wire, to ANY Black wire.
ALL Black wires are Ground wires.

Go to the link with the 24-pin ATX main power cable, in it.
Look at the photo to the far right. See the Green wire?
See all the Black wires?

The preferred jumper wire is a paper clip, straightened out, then bent into a U-shape. The middle of the U is wrapped a few times, with black plastic electrical tape. This taped area is for your fingers, and thumb to hold onto.

Turn the U over. Taped middle is up. There are now two 'legs'.
These legs go down into the socket holes, of the Green wire, and ANY Black wire.

One 'leg' down into the socket hole of the Green wire, the other 'leg' down into a socket hole with ANY Black wire.
The 'leg' of the jumper wire, goes down RIGHT NEXT TO the wire already in the socket hole.

The 'leg' has to go down into the socket hole, (Next to the wire already in the socket hole), pretty far.
It has to go past the insulation of the wire, and touch a metal terminal, that is on the end of the wire.

Look at the middle photo. Here you can see the metal terminals, in the socket holes.

Again, Power Supply plugged into power. ATX main power cable plugged into the motherboard, just like the photo to the far right.
The jumper wire makes a contact of no more than 2 seconds.

(Stick the jumper wire down in the socket holes, no more than 2 seconds, then pull it out.
The ATX power on switch is a Momentary Contact Switch )

Power supply comes on? You have a bad Power On switch,

Power supply does NOT come on? You have a bad Power Supply.

Dear Sir, my mother board d101 has been damaged can i use of p4sd m/b insted of that while i want all rest parts remain using i dont want change ram,SMPS, Proccesser etc.


fbhushan, the Intel D101GGC motherboard (Grand Country) supports;

1) Intel Pentium 4, Intel Celeron D, and Intel Pentium D processors that fit in an
> LGA 775 processor socket.

http://en.wikipedia.org/wiki/LGA_775

The Processor has the socket holes, and the processor socket (LGA 775) has the pins.
775 socket holes, and 775 pins.

The Front Side Bus (FSB) can be either 533MegaHertz, or 800MHz.


2) Supports DDR Sdram ram memory at either 333MegaHertz or 400MHz.
(PC2700 and PC3200, respectively)

Will support Up To 2GB of ram memory.
Has two ram memory slots. The maximum amount for EACH slot is 1GB


3) The SMPS used for it has,
A) One 24-pin ATX main power cable

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

B) One 4-pin ATX +12 Volt power cable,

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


The Intel D101GGC motherboard has Four SATA headers (Connectors) on it, so I'm going to assume you are using a SATA harddrive.
This would mean the SMPS you are using should have at least one SATA power cable.

It should also have an assortment of 4-pin standard Peripheral power cables.
(Misnomered as 'Molex')



The Asus P4SD (Motherboard chipset Intel 865PE) supports;

1) Intel Pentium 4 and Intel Celeron processors that fit in a > Socket 478 processor socket

http://en.wikipedia.org/wiki/Socket_478

The Processor has the pins, and the processor socket has the socket holes.
478 pins, and 478 socket holes.

Your Processor will NOT work.

The Ram Memory WILL work.

The SMPS MAY work.

I state MAY because the Asus P4SD motherboard uses a 20-pin ATX main power cable.

If the last four pins of the 24-pin ATX main power cable that you have on your SMPS right now, Do Not remove, you can Carefully cut them off. Wrap them up, and out of the way.
If you need guidance on this I can help instruct you.

You need an IDE (PATA) harddrive, or a SATA adapter card to use a SATA harddrive.

So there you have it sir.
