SOURCE: inno3d 9800gt is it compatible with asus p5vd2-mx motherboards?

What I beleive is your problem is that a single 4Pin connector doesn't provide enough of the right power connections. I have a 9600GT and like you my PSU doesn't have a 6pin connector. But fortunately for me the manufacturer of my card (BFG) had the Foresight to include the adapter that I need (Which was a Y cable with 2 4pin (Molex) connectors to one 6pin (PCIe) connector.

First thing I'd do is check ALL of your packaging to see if your manufacturer also included such an adapter. It may be hiding (Taped to the inside of the cardboard packaging or stuffed in a bag with papers/warranty info)

Retail boxes usually list the parts included so you can look to see if a "duplex molex to PCIe" is on it.
If this search proves futile, you might check at your local PC hardwarestore (Best buy, Circuit city, or if you have a specialty store like MilwaukeePC here in Milwaukee)

If that is not an option and you have a credit card/Paypal account you can try an online retailer such as NewEGG or CDW jsut add the dot com to their names for their websites.

I hope you find this Usefull

SOURCE: acer m464 front panel connectors

Sorry in the 1st instance for my lack of specific knowledge when it comes to ACER hardware.

Is the model of your MOTHERBOARD - Acer m464?

If so do you happen to still have a manual that came with the motherboard?

Sometimes you can see the pinout in white writing on the mainboard itself near the connector block... have a close look and see if it is there.

The pin out for the connector block will definately be in the mainboard manual. If you don't have the manual then you'll need to do a little searching for it... I'm sure a .pdf of it will be floating around... i guess start at the ACER site.

On the rack mount chassis, are the plastic chassis connectors grouped (ie. 2 wires into 1 connecter for pwr led, etc) or are they individual single pin connectors?

Either way for each group, one should have a little TRIANGLE on the opposing side to the writing. Conventionally this is your positive (+) pin when looking at the pinout diagram. Ensure you have correct polarity for all ur connections obviously.

See how you go mate.

I have tried running 2 different M4A79 deluxe motherboards with a corsair 650W power supply, phenom I X4 processor, and an nVidia 9800GT video card but neither of them will so much as turn on with...

It sounds like the ATX power supply is not getting turned on by the motherboard.
In order for this to happen, pin 14 (PS_ON*) of the 20-pin ATX power plug from the power supply must be pulled to ground. You can test this by plugging the power supply in to AC power without it plugged in to the motherboard.

Using a paper clip, short pin 14 (PS_ON*) to pin 15 (ground) and the power supply should turn ON.

Looking at the front of the 20-pin plug, with the latch on the top, pin 14 is the 4th from the left

Front of 20-pin ATX Power Connector

If you can turn on the power supply by shorting pin 14 to ground, but it doesn't happen when plugged into the motherboard, there is most likely a jumper setting on the motherboard which has not been configured correctly.

I hope this helps!

I am replacing a motherboard with a G31-M7 TE and find that my existing power supply has a 20 pin plug consistant with the old motherboard but the new one has a 24 pin socket. Why is this and do I need to...

New motherboards have a 24-pin power connector. Here is a diagram of both plugs:


You can see that the two are almost identical. The extra 4 pins on the 24-pin connector provide extra connection points for a few voltages. Newer boards and processors need more current, and the extra pins were added to prevent overloading.

Adapter cables are available to go from your 20-pin power supply plug to the 24-pin motherboard connector. Here's one from TigerDirect, and other vendors have them as well. If you're not making other changes than replacing the motherboard, you shouldn't need more than this adapter.

If you are upgrading your processor along with the motherboard, you should probably replace the power supply too. Older power supplies are often in the 300-watt range, and this is too low for reliable operation with new processors, motherboards and video cards. A new 500 or 600-watt supply is not expensive, and would give you the 24-pin power connection the motherboard needs.

Hope this has helped. Thanks for using Fixya!

I have the P5GC-Mx/1333 asus motherboard. I set a password for bios a while back, but i've forgotten it. How can i reset it?

Remove the small battery for the bios settings. It's a round type like this:
Leave the motherboard some minutes without battery. Replace the battery after a while, start up and get into the bios, load set up defaults, save and reboot, get into the bios and make any settings you wish (date, time e.t.c.)

In case of a problem or clarification, don't hesitate to post me a reply before rejecting my answer.

Do I plug in BOTH the 20+4 ATX power connector AND the 8 pin 12V connector on a gigbyte MB (MA790GPT-UD3h)?


You only need to plug the 20+4 ATX power connector and how about the 8 pin 12V connector? Well that is use only for legacy type of motherboard that use to require it.

Hope it helps..

Thanks for reaching Fixya

Connect +plug in power - plug in

You cannot get this wrong.. The power plug is a 24 pin connector and it will only fit in one place on the board. You cannot plug it in wrong as it will only slide in the correct way. The 4 pin connector is the +12volt connector, again, you cannot plug this in wrong either. The power connectors to the drives are also 4 pin but they are a flat plug which again, cannot be plugged in the wrong way around. The data cables are very different. IDE cables are a 40 or 80 pin square connector. Each connector may have a key which fits into a socket on the mating connector so again, it will not go in the wrong way. If it does not have this key, then the red stripe on the cable shows pin one and if you look at the mainboard connector, pin one is usually marked on the board.SATA connectors are profiled, that is they are shaped and will only fit the one way. the power connector is a different size (its bigger) then the data connector so you cannot get these plugs wrong either..

3 pin fan on heasink to 4 pin fan replacement HELP!!!

4 pins "PWM" fans are specially designed for use with newer motherboards which have 4-pins CPU fan-connector, but the fans are backwards compatible with 3-pins connectors. Just plug the 4-pins fan-header into a 3-pins connector (only 1 way possible) and you're good to go (although you don't get the "PWM" advantages).

You can find more information about the different type of computer fans here:
