The Asus P5GC-MX/1333 motherboard, uses an Intel 945GC motherboard chipset,

When installing in the PCI Express x16 slot on the motherboard, (Black. Gently lift up on Locking Arm to install card. Looks like you press down), there looks to be enough room.

There are Radial Aluminum Electrolytic Capacitors that stick up, on one side; and one of the white PCI slots on the other side.

Nvidia GeForce GTX 560 is a wide graphics card,

Just one manufacturer. Size varies a little from manufacturer to manufacturer.

Minimum power requirement is 450 Watts.

Now bear in mind that this is for a complete computer system.
NOT, what just the graphics card requires for power.

Since there is no additional power cable to be connected, to the graphics card, the graphics card ONLY uses UP TO 75 Watts.

This is known because a PCI-Express x16 slot, will deliver UP TO 75 Watts.

If a graphics card requires more power, then a 6-pin PCI Express power cable is used. It will deliver an additional 75 Watts, bring the available power for the graphics card UP TO 150 Watts.

Graphics card requires more power than that?
Then an 8-pin PCI Express power cable is used. This power cable can deliver UP TO 150 Watts.
With PCI Express x16 slot, you are now looking at 225 available Watts,

[NOT to be confused with the 8-pin EPS +12 Volt power cable. This power cable is used for the MOTHERBOARD, NOT a graphics card,

The connector on the Top of the graphics card, is for SLI.
Scalable Link Interface,

Does GA-G41M-ES2L Motherboard support asus gtx 650 graphic crad?

Motherboard chipset;
Intel G41 Northbridge; Intel ICH7 Southbridge,
(The Intel ICH7 is also Intel part number 82801GB)

(CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor for short)

G41, scroll down towards the bottom of the chart.
(Past P45)
Introduced in the last quarter of 2009

The PCI Express 2.0 technology came out January 15, 2007

Means your PCI-Express x16 slot is based on the PCI Express 2.0 technology

The Asus GTX650 graphics card, (No matter which version), is based on the PCI Express 3.0 technology

PCI Express 3.0 technology is Backward Compatible, with PCI Express 2.0 technology,

"PCI Express 3.0 Base specification revision 3.0 was made available in November 2010, after multiple delays. In August 2007, PCI-SIG announced that PCI Express 3.0 would carry a bit rate of
8 GigaTransfers per Second, (8GT/s), and that it would be backward compatible with existing PCIe implementations."

PCIe =PCI Express

So yes it will work, AND will work at FULL capacity.
Also your motherboard chipset (Northbridge), will support Intel processors that utilize an LGA 775 processor socket, AND up to an Intel Core2 Quad CPU. (Processor)

You need a Power Supply that will not only deliver the necessary Wattage, for the computer system; but also need Up To an additional 150 Watts JUST for the graphics card itself.

Know what happens when you try to under power, a powerful graphics card?

Things BURN,
The computer doesn't work

A) The contact pins in the PCI-Express x16 slot, will burn
B) The gold plated contact pins on the bottom, of the graphics card will burn

C) The graphics card requires more power, than the PCI-Express x16 slot can deliver.
A PCI-Express x16 slot can only deliver Up To 75 Watts.

A 6-pin PCI Express power cable is required.
This power cable can deliver Up To 75 Watts.

If there isn't enough power the contact pins, in the 6-pin PCI Express power cable will burn.
So will the contact pins for the power cable, on the graphics card.

The motherboard by itself requires 120 to 150 Watts.
Depending on Processor, Up To 130 Watts.
For each stick of Ram Memory add 25 Watts
25 to 30 for each Optical Drive. (CD/DVD drive)
2 to 3 Watts for each fan; to include the Processor fan, and computer case fans.

Now add 150 Watts for the graphics card.........

Is not Reading My Geforce GTX 260 Card

What do you mean connect wire to graphics card?

A) Computer is to be OFF when connecting a monitor cable.

B) Computer is to be OFF, and unplugged from power; when plugging the power cable from Power Supply, into it.

You are also supposed to be Following Anti-Static Precautions.

What Power Supply are you using?
Manufacturer name, and model number. Post back in a Comment.

Motherboard requires about 150 Watts by itself.

That isn't including what the Processor (CPU) needs, Ram Memory needs, optical drive/s need, computer case fans need; AND what the Nvidia GeForce GTX 260 graphics card needs.

It needs 225 Watts by itself.

(Manufacturers usually state around 500 Watts MINIMUM.
This is in reality based on a COMPLETE computer system, and NOT just the graphics card itself)

What do I base that the GTX 260 needs 225 Watts?
(I see that as the -> Maximum, though )

A PCI Express x16 expansion slot on a motherboard, is only capable of 75 Watts of power.
That is why the additional power cables were brought out.

The 6-pin PCI Express power cable that plugs into the GTX 260, is capable of an additional 75 Watts of power.

The Nvidia GeForce GTX 260 requires using TWO 6-pin PCI Express power cables

That means 150 Watts of additional power.
75 Watts + 150 Watts = 225 Watts

"Supplementary Power Connectors -> 6-pin x2"

If you are using just one 6-pin PCI Express power cable, '
this = NO.

NOT enough power for the graphics card.

What will happen?

A) The PCI Express x16 slot connector oins, will burn
B) The gold plated contact pins on the bottom of the graphics card, will burn.
C) The connector on the graphics card, that the 6-pin PCI Express power cable plugs into, will burn.
D) The connector on the 6-pin PCI Express power cable will burn.

The graphics card will burn up.
Too little power.

IF, your Power Supply has enough power, and IF there are two 4-pin Peripheral power cables that aren't being used; you can use a 6-pin PCI Express power adapter cable.

Example of 4-pin Peripheral power cable,

Example of 6-pin PCI Express power adapter cable, was shown in the Playtool link,

Is p4c800 deluxe compatible with an nvidia geforce gtx 550 ti (1 Gb)?

The Asus P4C800 Deluxe motherboard uses an AGP expansion slot, for a graphics card, Jorgito.

The Nvidia GeForce GTX 550ti graphics card is a PCI Express graphics card. Uses a PCI Express x16 expansion slot,

No sir, is the answer.



You need an AGP 8X graphics card.
Here is but one example,

You also need to look at what your Power Supply maximum rated Wattage is. Then look at the system requirements for the graphics card, and see what the -> MINIMUM power supply requirement is.

For the above graphics card it is 400 Watts, OR greater.

Hi bain_j,

your motherboard has a slot for this. I have encircled the slot on the picture I have attached. Also I checked and the current Power Supply that came in with your HP Pavilion will not be able to support the card. You would need to get a new power supply unit preferably around 600 watts and with a PCIE 6-pin power. I hope this helps. Please let me know.

I also need Your OS.

making yourself nuts, test the monitor on another PC or laptop. If you use a laptop to test the monitor and it doesn't automatically detect an external monitor when booting, use the "F" function keys along the top of the keyboard to tell the laptop to shift to the external display. Remember that we are testing just to see if the monitor is live, it doesn't matter if the screen settings are wrong and the display looks funny. If it doesn't work on a known good computer, the problem is with the monitor, not your PC. If a faint image is detectable on an LCD screen, the problem is with the backlight or the inverter that powers the backlight. A loud buzz coming from an LCD monitor is most likely the inverter circuit failing, though it can go on getting louder for years before it pops.

Assuming the system power comes up, does the monitor power come on? Monitors have a status LED on the front bezel that should show green, orange, or blinking if the monitor is powered on. You can also hear older monitors power on with a gentle sound, though I can't describe it beyond saying it's the sound of a CRT tube warming up. Make sure the monitor is plugged into a good outlet by testing the outlet with a lamp or any other device that will prove beyond a doubt that the outlet is good. Make sure that the power cord is either permanently attached at the monitor end or that it is seated fully in the socket, since partial cord insertion is the most common failure for monitors with detachable cords.
LCD displays don't make any sound when you turn them on, but they don't always have a simple power cord, either. Some LCD monitors are powered by an external transformer, which in turn is powered from a regular AC outlet. If the LCD display doesn't show any signs of life, make sure that the cords into and out of the transformer are fully seated. Some transformers are equipped with a status LED to show when they are operating, though you can also check for live output with a DC voltmeter. The power connection to the LCD display is often awkward to inspect, recessed into the back of the display. The important thing is to make sure it is started correctly, then seat it all the way.
If you see a message on the screen that includes "power" in it, like: "attach graphics card power", "no power to video adapter", etc, it means that you have a PCI Express or older AGP video card that requires more power than the motherboard can supply through the bus. This means you need to run a power cable directly from the power supply to the video adapter, inside the PC. If it's a new build, you may have forgotten or not seated the connector firmly. If it was a working PC, either the power supply lead has failed, the power supply itself has problems, the cable worked loose, or some hardware on the video card has failed.
Earlier video cards that required additional power from the power supply usually took a Molex connector, the same 4 pin connector used to power non-SATA drives. Newer power supplies include one or two six pin PCI Express supplementary connectors designed for power hungry graphics cards. Some PCI Express cards, in the absence of a six pin supplementary lead, will accept two 4 pin Molex leads.

Yes it would likely power a graphics card but not very well. I would suggest at least a 500 watt power supply. and about not having six pin connectors you can get an adapter to convert two molex connectors to one six pin connector.

Well, this pretty much comes down to how much $ or € or any other currency you're willing to spend as well as what games you're most likely to play.

If you don't wanna spend a fortune but still get a very good and reasonable performance, you could try GeForce 7600 GT or 7800 GT [7800 GT being better]. Both of these can be had quite cheaply these days. If you want something even more powerful that doesn't require you to sell a kidney on E-bay, then try GeForce 8800 GT, more precisely MSI NX8800GT-OC. Compared to ordinary 8800GT's, this one's beefed up just a bit more. Alternatively - if you can find that specific mode - almost any would do; still, I'd recommend Asus EN8800GT.

As you may have noticed, I've suggested only nVidia cards: I've never been too much into ATI + nVidia is leading the race these last few months. However, if you want to swing ATI way, then instead of 7800 GT find yourself a some ATI 1950 XT or whatever they call it. It is roughly equivalent to the 7800.

For high end ATI's, look for 3850 HD or something akin to that - there's a lot of review online.

Remember: read reviews first - shop later.

P.S. Make sure your PCI-Express x16 slot really is a x16 by reading your motherboard manual.


Hope it helps. Rate me. Thanks.
