Foxconn 760GX K8MC-S

I changed the power supply and put a new one which is 500 watts. I plugged all the cables the same way they were plugged with the old power supply. I then turned on the swith from the power supply the power light came on and the power supply fan and processor fan came on and the motherboard starts to boot up for about three seconds and then it goes off. I turned off the switch from the power supply and turned it on again and it does the same thing. I hit the power switch from the case to see if it comes back on but it doesnt. I unplugged the power switch and turned it on with the power supply switch and it does the same thing it goes on for a few second and then turns off. I cleand the processor fan to make sure is not an overheat situation but it's not that. What can I do to to correct this problem. I have check all the wires, removed the led, hdd, and reset switch and still nothing, what can I do or check that I have'nt done yet ? Thank You for your help.

Hi...

You already have done your best and yet it still does not work... Same problem I have last week... but I have changed the motherboard with anew one and it worked perfectly again... That is I had to break my piggy bank.

Sorry my friend...

Can i put gaming power supply to my msi rc410m-l?


Hello here is the mainboards homepage:

http://www.msi.com/product/mb/RC410M-F--L--FI--LA.html#/?div=Detail

Any ATX power supply will fit your mainboard.

I will recommend to buy a power supply of a good brand like corsair, because the cheap one does not last long.
I would choose one not under 500 watts.

If you change the powersupply yourself, please take antistatic precautions when working on the mainboard.

Pricerange is 100 to 200 dollars depending on how big it has to be.

Remember also to arrange cables so its not blocking vents and fans.


Good luck

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

http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-260/specifications

"Supplementary Power Connectors -> 6-pin x2"

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

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,

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

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

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

New GA-990AX-UD3 motherboard will not boot


You really should take that Power Supply, and use it on grandma's computer.

The 8-pin EPS +12 Volt power cable was brought out, to provide more power To the motherboard AND processor.

http://www.playtool.com/pages/psuconnectors/connectors.html#eps8

The 4-pin ATX +12 Volt power cable has TWO yellow wires.
Yellow wires are 12 Volt wires. (And two Black ground wires)

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

The 8-pin EPS +12 Volt power cable has FOUR 12 Volt wires.

In the motherboard manual, does it say, "Yes Tom. Go ahead and use a 4-pin ATX +12 Volt power cable. We don't care. We just use an 8-pin EPS for fun."

[ This is an 8-pin PCI Express power cable. Completely different,

http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress8 ]

The motherboard probably uses 150 Watts by itself.
No Ram Memory, no CPU, no fans, etc.

The CPU could use up to 125 Watts of power. Just depends on what AMD, socket AM3, processor you are using.

Now to graphics card's power;
The most Wattage a PCI-Express x16 slot can deliver is 75 Watts.

The most power a 6-pin PCI Express power cable can deliver is 75 Watts.
8-pin EPS +12 Volt power cable? 150 Watts.

When buying a Power Supply you should calculate all components needing power,

http://extreme.outervision.com/psucalculatorlite.jsp

,then buy a Power Supply that has AT LEAST 10 percent more power than needed. Easier on the Power Supply.
Also a computer will NOT use more power than it needs.

10,000 Watt power supply, (Exaggeration ), and the computer only needs about 100 Watts for surfing the internet?

Computer ONLY uses 100 Watts.

Due to the price, the above, and the availability, you should use a 500 Watt power supply at least.

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=899123&CatId=1079

http://www.amazon.com/StarTech-6in-Pin-Power-Adapter/dp/B002O21XHQ

Or use it on yours if it has enough Wattage.

Back in the day, the motherboard didn't need to supply that much power to components on it.
More powerful Processors, Ram Memory, and graphics cards, brought the power needed, up.

A 4-pin ATX +12 Volt power cable was added for the motherboard. Then 6-pin PCI Express power cable for graphics cards. Then the 8-pin PCI Express power cable for graphics cards. Lastly the 8-pin EPS +12 Volt power cable.

(Better make sure the Power Supply you have is good, if you wish to use the above power adapter cable. Nothing like having a Power Supply with a weak voltage power rail, and a new build, to pull your hair out on )

http://www.gigabyte.com/products/product-page.aspx?pid=3894#ov


Out of the motherboard manual Page 23,

"With the use of the power connector, the power supply can supply enough stable power to all the components on the motherboard. Before connecting the power connector, first make sure the power supply is turned off and all devices are properly installed. The power connector possesses a foolproof design.

Connect the power supply cable to the power connector in the correct orientation. The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not connected, the computer will not start.

To meet expansion requirements, it is recommended that a power supply that can withstand high power consumption be used (500W or greater). If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system."

sounds like you need a higher wattage power supply!! meaning if you have a 500 watt power supply and it burned up then you may need a higher wattage power supply!! try a 650 or 750 watt power supply. there is only 4 screws holding the power supply in place, just un-plug all internal power cables and remove the screws and do the reverse with a new power supply. please go slow the connecting internal power cables are keyed meaning that they only fit one way!!! DO NOT FORCE THE PLUGS INTO THEIR SOCKETS OR YOU WILL BLOW UP YOUR MOTHERBOARD!!! sorry for the caps!

My new video card Sapphire HD5770 is installed and now my pc will not post or boot, what can i do?


Make sure you have your card installed correctly in your PCIe slot, it should hook in. You also have to hook up power supply. This card requires minimum 450 watt power supply and 600 watt power supply if using crossfire and dual mode. If your system meets these requirements, and you have card seated properly and hooked to power supply. You may have to enter your bios and dedicate the PCIe slot. I'm guessing the system will boot without card.

You can use just about any WATT power supply. The demand of wattage is limited to the use of each item that the computer needs to operate correctly. So you can't blow out your system if you install everything correctly and properly. So you could install a 1Giga Watt with safety. Make sure that the power supply that you get fills the needs of your video card.. Reference the video card box for the proper Power supply..

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:

pgh_pa_guy_3.jpg

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!

No Power!


So, have you checked first with a multimeter to see if the wall outlet is getting power. Next, check the power cord.

Have you also checked the power supply with another system. Just make sure you didn't hook up to many devices to the power supply. If you did, then it wouldn't power up.

If you are getting power from the power supply in another unit, then disconnect any add-on cards, optical drives, floppy drives, etc. and just boot from your hard drive.

If you still don't get anything, check the CMOS battery to make sure that it is at 3 V. Some motherboards won't boot if that battery is to weak.

Also, what type of thermal grease are you using. Is it the white paste or phase change material or arctic silver.

The white paste dries up and doesn't cool effectively. Also, how thick did you apply the paste or phase change material. The thinner the coat the better.

What type of RAM are you using? Is it compatible and did you reseat it as well as the CPU.

Check the RAM in another computer as well as the CPU. If the RAM and CPU is good, then the motherboard you got is defective and needs to be replaced.

If you don't get anything at this point, then eitherthe motherboard is at fault.

If you don't get anything at this pointyour power cord is getting power.

Upgrading power supply


The next time you get a PSU. Tell them what you have. Apparently you got one that is not compatible with your compaq.The power (500 wattage) will work with your MB.
Get an OEM PSU from Compaq(HP).
