Question about IBM NetVista X41 PC Desktop

1 Answer

On-The-Road with a PC Desktop

The X41 uses a 110vac Power Adapter to a 12vdc 6-pin connector on the back of the PC. I have not verified the volts at each pin... but my real question is this: Can I wire up a power cable to my 12vdc motorhome batteries ? I did this with a TV and a DVD player and they work fine.
It seems silly to power the motorhome's AC "converter", then plug in the Power Adapter to convert the 110 back to 12vdc.

( FYI... this is NOT like running a laptop with 12vdc. Laptops have batteries, and get their power thru their charging circuitry )
Thanks in advance & Merry Xmas !

As long as the Voltage matches it does not matter where the power originates from. The voltage must match exactly to the adapter readings. Hope this helps.

I need a new graphics card - are they still available for this make & model and what is the name & type of card I need to buy?


gateway support shows you have a pci-e x16 slot for a video card

you can choose a non-powered pci-e video card for your system, which might be better for you if you still have the stock power supply in your tower.

or, you can choose a powered pci-e card if your power supply is powerful enough to run your system AND a pci-e video card too. a powered card will have a spot for a 6 pin (or 2x 6 pin or sometimes a 6 pin and/or an 8 pin) power connector that comes from your power supply to the video card ... you may have to replace your power supply to use a powered card, or get a pci-e power adapter (not the preferred method, but sometimes works).
here is an example of a non powered pci-e card
and here is an example of a powered pci-e card, see that black connector near the back of the card, that's the power connection

and the 6 pin connector from the power supply looks like this (and power supply adapter shown also)


does this help?

How to wire up a 650 graphic card

You're going to need;

A) 2 miles of No.00 wire.
B) SpreadNok cable clamps
C) A pair of Klines
D) 2 rolls of black plastic electrical tape


your Power Supply needs a 6-pin PCI Express power cable,

Plug it into the Top/Back of the graphics card.

(I watched the video)

Your PCI-Express x16 slot can deliver up to 75 Watts of power.

The 6-pin PCI Express power cable, can deliver up to 75 Watts of power.

Minimum of a 400 Watt power supply is needed.

Looking back at the Playtool link, and the 6-pin PCI Express power cable;

Note the 6-pin PCI Express adapter power cable, shown on the right.

THIS, is what you use if your Power Supply, does NOT have a 6-pin PCI Express power cable.

TWO 4-pin Peripheral power cables plug into it.

I say again...............TWO 4-pin Peripheral power cables plug into it.

DO NOT use just one.
I don't care, if that is all the 4-pin Peripheral power cables that were left.

If you use just one 4-pin Peripheral power cable, you will;

A) Burn the gold plated contact pins on the bottom of the graphics card.

B) Burn the contact pins down in the bottom of the PCI-Express x16 slot.

C) Burn the plug connector end on the 6-pin PCI Express adapter power cable.

D) Burn the contact pins on the graphics card, that the 6-pin PCI Express power cable plugs onto.

Happen right away?

Down the road a little after you have forgotten all about it.

("Hmmm, what's that smell? Smells kinda' like burnt wiring.
Wow, my monitor screen just went blank."

News at 6:00
"Nvidia GeForce GTX650 graphics card buried today, along with a motherboard.
Owner cited for neglect, pain and suffering.
Plea bargained to do better in the future" )

Not having a 6-pin PCI Express power cable on your Power Supply, suggests it is a low quality unit, and is underpowered for that graphics card.

Want to burn up a graphics card, just under power it.

[ 4-pin Peripheral power cable;
Also misnomered as a 'Molex' power cable.

Molex was the first company to produce that design of power cable CONNECTOR.
(I don't think they designed it, just manufactured it; if memory serves)

Name stuck. Kinda' of like calling an open-end wrench a 'Crescent wrench' ]

Where does the wire labelled P7 from the power supply from Dell studio XPS with 6 pins goes?


A) If you have this type of power cable it connects to the motherboard,

B) If you have this type of power cable it connects to a graphics/video card,

C) If you have this type of power cable it connects to a graphics/video card,

(Power adapter cable is shown on the right. Used if the Power Supply does Not have a 6-pin PCI Express power cable)

Do not have a graphics/video card that requires a 6-pin PC Express power cable?
Loop the cable up out of the way, tie it with a PLASTIC zip tie.
(Do NOT use a bread tie. Has a metal strip in the middle)

1 Answer

T5274 power supply spec

That's easy Lou


Primer first before I give a recommendation. I ABHOR just posting,
"Oh, use this one".
I like to teach, so that you can use deductive reasoning based on intelligent thought.

Because for one eMachines are a budget computer. As such they use low quality budget Power Supply's.

Probably a generic Bestec, Hi-Pro, or Delta, power supply.
250 to 300 Watt.

12 Volt power rail is probably 12 to 14 Amps.
Nothing to write home to Mom about. Just an internet, or office program computer, with compatible power supply.

The size, and shape of the power supply's case is an ATX.
Approximately 6 Inches Wide, by 5-1/2 inches Long (5.5), by 3-1/2 Inches Tall. (3.5 / Height)

ATX also refers to that is has a Soft Power On feature, plus refers to the power cables it uses.

The eMachines T5272 Desktop PC, came with an ECS 945GCT-M3 motherboard, according to my records,

To the right of the blurred motherboard photo, click on - More pictures.

1) Requires a 24-pin ATX main power cable.
Long blue connector on the right side of the motherboard, is for the IDE harddrive.
Above it the black long connector is for a Floppy Drive. To the left of the Floppy Drive connector, is the motherboard's 24-pin ATX main power cable connector.

Average example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,

[Note* Color does NOT matter for any power cable connector, or it's matching connector on the motherboard ]

2) Requires a 4-pin ATX +12 Volt power cable.
To the left side of the Processor socket are 6 polymer solid capacitors. To the left of them are three choke coils. Right below the last choke coil, is the motherboard 4-pin ATX +12 volt power cable connector.
An average example of a 4-pin +12 Volt power cable, and it's respective connector on the motherboard,

This is power for the Processor.

3) Since there are four black SATA headers on the motherboard, I imagine you will be using a SATA harddrive. (Can also use a SATA optical drive too. {CD/DVD drive)

You will need a SATA power cable for each SATA device.
Average example of a SATA power cable,

[ Note*
IF, your SATA harddrive has a provision for a SATA power cable, AND a 4-pin Peripheral power cable, ONLY use the SATA power cable!!

Otherwise you will burn out the SATA harddrive! May not happen immediately, but I ASSURE you it will happen down the road.

Average example of a 4-pin Peripheral power cable,
(Erroneously referred to as a 'Molex' power cable. Name stuck, just like calling an adjustable open-end wrench, a Crescent wrench ),

[Also, it is a Standard 4-pin Peripheral power cable. The one used for a Floppy Drive, is a Small Peripheral power cable. Now used for power to a Card Reader ]

D) Standard 4-pin Peripheral power cable/s. May need for computer case fan/s, besides the one on the motherboard, or power to an IDE optical drive, or IDE harddrive.

Primer over.

Recommendation, and why;

[NOT advertising for said website. You may find a better price from another reliable dealer. Do a search ]

1) 140Millimeter Fan.
A larger fan runs slower than a smaller fan, (80mm), and puts out more air. This makes it quieter, and has more efficient cooling.

UNLESS, of course you are gaming! Will put out more noise. But, let's be real here. If you're gaming, with the sound up, are you going to hear the fan? Lol!

2) It's SLI ready. Which means it's also CrossFire ready. Can run two graphics cards.

You can use the 6-pin PCI Express power cable for one graphics card, and use the 6-pin PCI Express power cable, from the 6-pin/8-pin PCI Express power cable, for the other graphics card.

3) There are TWO 12 Volt power rails. Yes, still actually comes from one main 12 volt power rail, but divided amperage between the two.

25 Amp's for EACH 12 volt power rail.
Yes, you can total that up to 50 Amps for 12 Volt power.

4) Has all the power cables you'll need now, and possibly for the future.

5) Is reliable. Has an 80 percent efficiency rating, but at a 480 Watt power load it is 83.5 to 86.6 percent efficient.
81.9 percent efficient at 600 Watts,

[Suggest read the entire article. This website is VERY proficient at testing power supply's. Does NOT care what the manufacturer thinks. They tell the Truth. They also are the only website to my knowledge, that has an EXPENSIVE power supply tester. Tests the LOAD, for one thing. They also 'dissect' the power supply, and look at all components inside ]

6) The price.
Do not have to 'Break the bank', to get more bang for your buck.

I have installed two diferent graphics card, #1 was MSI 5459 and #2 was a Nvidia GeForce 250. Bth ran fine afor a short period of tme #1 for a month an #2 for about 2 weeks. After these periods of time...

I don't find the MSI 5459 graphics card, William.
Am familiar with the Nvidia GeForce 250 GTS, though.

Using the GeForce GTS 250 as an example, the graphics card requires a 6-pin PCI-Express power cable, for additional power, along with the power it gets from the PCI-Express x16 slot it is in.

The unit is furnished with an adapter power cable, that converts 2 Molex power cables, (4-pin Peripheral power cables, actually), into 1 PCI-Express 6-pin power cable.

Note that the 6-pin PCI-Express power cable, has two Yellow wires in it.

Let's look at a 4-pin Peripheral power cable,

Note there is one Yellow wire, one Red wire, and two Black wires.

The Red wire is a 5 Volt wire, and not used by the adapter power cable.

The two Black wires are Ground wires, and only one is used by the adapter power cable.

The Yellow wire is a 12 Volt wire, and is used by the adapter power cable.

The 6-pin PCI-Express power cable requires TWO Yellow 12 Volt wires.
(And three Black Ground wires)

This means Two 4-pin Peripheral power cables MUST be used.

Failure to use two 4-pin Peripheral power cables, to that adapter power cable, means the GeForce GS 250 is NOT receiving enough power.

This will burn the connection at the graphics card, burn the adapter power cable connector, and burn the PCI-Express x16 slot it is sitting in.

Takes time, but will happen.

Could this be what you have done?

It also requires 150 Watts all by itself. You need more power for the rest of the computer.

(The 6-pin PCI-Express power cable is designed to provide up to 75 Watts of power. This means 75 Watts of power, also comes from the PCI-Express x16 slot, it is sitting in)

Nvidia GeForce GTS 250,

Not a problem, but it would be handier to have the manufacturer Name, and Model Number.

(Back of computer on a sticker, next to the Windows product key, or up on the side of the computer tower )

SMPS = Switched-Mode Power Supply. The style used in personal computers now,

A) Main power cable:
There are three styles;

1) The old AT style that has two separate connectors. The connectors BOTH connectors have BLACK wires towards one side.

The connectors also have ONLY one way, (Direction), they can be plugged onto the motherboard.
This is due to the Lock, and Locating Tab on the motherboard connector/s, and the main power cables connector/s.

When you can plug the connectors on the motherboard, with both connector's BLACK wires facing each other, (They will be in the middle), you have them installed correctly,

2) The newer ATX style. Uses one power cable, and connector.
First style to come out was the 20-pin ATX main power cable,

20-pin ATX main power cable's connector, has a LOCK on one side.
This Lock locks over a Locating Tab, on the female motherboard connector.

To remove this power cable you squeeze in on the Top of the Lock.
The Lock operates like a see-saw on a playground. When you squeeze the top in, you remove it's hooked end away, from the Locating Tab of the motherboard connector.

To be ensured that this cable is plugged in tightly, and correctly, the Lock's hooked end will be over the Locating Tab, on the motherboard connector.

3) The newest style is the 24-pin ATX main power cable.
As computer hardware evolved, and became better, it demanded more power.
The extra 4 pins of the 24-pin ATX main power cable provided this,

[ Aftermarket power supply manufacturers, provide power supply's with a 20 + 4-pin ATX main power cable, usually.
You can use it as a 20-pin ATX main power cable, or use the additional 4 pin cable, and use it as a 24-pin ATX main power cable ]

4) Motherboard didn't provide enough power for newer Processors.
The 4-pin ATX +12 Volt power cable was brought out.
(Has Lock with Locating Tab on the motherboard connector, also)

5) Motherboard didn't provide enough power for high-end graphics card.
4-pin ATX +12 Volt power cable didn't help.
The 6-pin PCI Express power cable was brought out,

Plugs into a graphics card.

[ Note*
In all power cables, Red wires are 5 Volts. Yellow wires are 12 Volts. ALL Black wires are Ground wires ]

Next in line was two versions of the 8-pin power cable.

A) 8-pin EPS +12 Volt power cable.
Originally brought out for server computers, that has multiple Processors.
Plugs into the motherboard.

B) 8-pin PCI Express power cable.
Brought out for more power, than a 6-pin PCI Express power cable could put out.
Plugs into a graphics card.

(6-pin PCI Express power cable is capable of handling 75 Watts.
8-pin PCI Express power cable will handle 150 Watts )

If you have an IDE (PATA) harddrive, a 4-pin standard Peripheral power cable is what you need. ('Molex' is the slang term for it's connector)

If you have a SATA harddrive you need a 15-pin SATA power cable.

IF, your SATA harddrive has a provision for a 4-pin standard Peripheral power cable, AND a SATA power cable;

ONLY USE the SATA power cable!

If you use both you will burn out the harddrive. Maybe not immediately, but I assure you down the road you will.
(Do not use just a single 4-pin standard peripheral power cable, either)

Optical drive/s use a 4-pin standard Peripheral power cable, if they are IDE (PATA) units.
If they are SATA units they use a SATA power cable.

The old Floppy Drives use a 4-pin small Peripheral power cable.
Same cable plugs into a Card Reader, also.

The plastic front of your computer is the Front Panel.

The area of contact pins on the motherboard, that the cables, (Wires), from the Front Panel go to, is the Front Panel header.

Sometimes abbreviated on the motherboard as;
F_PANEL 1, or FP1, etc.

I will need to know the computer manufacturer name, and Model Number, (HP = Product Number, or P/N), or the manufacturer name, and Model Number of the motherboard, to TRY to provide this information.

What plug from the power supply on a FX541s computer do I plug into a nvida 9800gtx+ vidio card

A 9800GTX+ video card usually requires (2) 6-pin PCI-e power connectors from your PSU. The PSU that game with your computer might not have that. You can use an adapter that converts (2) 4-pin Molex to (1) 6-pin PCI-e connector. That does mean that you will need (4) 4-pin Molex power connectors.

Ibm netvista x41 wont power up

measuring 12v at the psu is not enough. the psu have several voltage outputs ranging from 12volts to 3.3 volts and maybe even 2.2 volts.. firstly, check all onboard USB ports, a bent or shorted pin in a USB port will prevent the psu from operating. next, the psu has a safety connection to the mainboard, this is called the power good signal ( pwrgd) and it is a signal from the psu to the mainboard and tells the mainboard that everything in the psu is functioning correctly. If the powergood signal is lost ( drops from 5volts to zero volts) the mainboard will issue an interuppt to the cpu and the cpu will shut down, this will also shut the board down to prevent damage and data loss. mainboards all use pretty much the same connectors so your board will have either a 20 pin power connector or a 24 pin one. It may also have an additional 4 pin connector to power the cpu and northbridge functions. use a known good psu and plug this into your board along with the 4 pin connector and attempt a switch on. If the system begins to boot, replace the psu. if not, try unplugging or removing everything connected to the board, pay special attention to expansion cards and usb ports. remove the ram sticks and video cards if fitted, then attempt to boot again. if the system does not respond, replace the main board. if it now begins to boot, refit everything one item at a time and try starting the machine. turn off before refitting the next item and start the machine up again. when you get to the problem item, the machine will stop starting. If all else fails, replace the mainboard or take the machine to a reputable repairer..
