Question about Biostar P4M800-M7A Motherboard

2 Answers

Pin Connection I am using a Biostar P4M800/8237 motherboard. After installing a new Video card, I noticed the cable that connects to my 9 in 1 card reader had pulled off the motherboard. I cannot find where it was connected. The connection is a 5 slot flat connector with 4 wires in it. Can anyone tell me where on the motherboard this connector goes?

It attaches to your choice of one of the two open and available USB sockets as I've circled in this image. Each USB socket has two horizontal rows of pins. A row with 5 pins. (the 5th extra pin is not used) A row with 4 pins. The first pin (on your left) is power, the last pin (on your right) is ground. ZT3000 "Beta tester of "0"s and "1's"

    Addition:

    I should add:
    Each row of horizontal pins in the socket corresponds to a single USB port.

    Looking at the image above, JUSB3 consists of two USB ports, the same with JUSB4.

Biostar Tpower x58 LGA1366 motherboard will not start or post


"I sent it for repair but it came back in the same condition!"

That means to me, spiritual_sky, that there is operator headspace.

Motherboard was fine when they tested it, and problem is on your end; Or they didn't test it, and shipped it back.

Going to go through the basics, so be patient. Mistakes are often made by those of us who are technically qualified, due to simple errors.

http://www.biostar-usa.com/app/en-us/mb/introduction.php?S_ID=390

A) The Support Plate the motherboard is mounted to, can be a separate plate, or is an integral part of the metal frame, of the computer case.

1) It looks as though there are 10 mounting 'holes'. (Manual gives no details. Looking at it right now. Going by Biostar Support page, and main view)

Is there a metal Standoff on the Support Plate, that does Not line up with the mounting holes? If so it is touching an exposed solder joint.
This = No

B) Have all the power cables needed connected to the motherboard?

1) 24-pin ATX main power cable. (Hooked end of Lock on power cable hooked over Tab on motherboard connector)

2) 8-pin EPS +12 Volt power cable.
Has 4 Yellow 12 Volt wires, and 4 Black ground wires,

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

Has a Lock on the power cable connector also, and Tab on the motherboard connector. When plugged in properly, and tightly, the hooked end is over the Tab.

Connects to Left Upper corner.

Not to be confused with an 8-pin PCI Express power cable,

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

[NOT an inference towards you, but I have seen people who could destroy a steel ball bearing in a sandbox, with a rubber mallet. They would try to cram an 8-pin PCI Express power cable, into a connector on the motherboard for an 8-pin EPS +12 Volt power cable ]

Three Yellow 12 Volt wires, FIVE Black ground wires.

A 6-pin PCI Express power cable will fit, and work, in a connector for an 8-pin EPS +12 Volt power cable.
Problem is it does -> Not, deliver the power that an 8-pin EPS +12 Volt power cable will deliver.

A graphics card senses whether a 6-pin, or an 8-pin power cable is being used.
SOME graphics cards will not work unless it is an 8-pin.

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

[See the power adapter cable on the right? Notice it uses TWO 4-pin standard Peripheral power cables. Some people make the mistake of only using one. This = NO ]

3) 4-pin standard Peripheral power cable. (Misnomered as a 'Molex' power cable)
Provides auxiliary power for the graphics card.
Manual states,
"This connector is an auxiliary power connection for graphics cards.
EXCLUSIVE power for the graphics card provides better graphics performance."

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

May be reaching here, but if the graphics card you are using does ->Not require an additional power cable connected directly to it, but does ->max out what the motherboard can provide, not connecting that additional 4-pin power cable may be the problem.

May need it even if the graphics card does have it's own power cable/s.

Graphics card requires a power cable? Better have it plugged in.
Requires TWO power cables? Better have two power cables plugged in, and Not just one.

Graphics has a problem? The motherboard will not start, or P.O.S.T.

Using a single Graphics card.
HAS to go in the PCI Express x16 slot next to the Northbridge chip, under the processor socket. (PEX16_1)

The PCI Express slot that is the same length at the bottom, is a
PCI Express x4 slot. This = No.

[Top slot next to Northbridge, {Copper finned Heatsink is on top of Northbridge chip},

PCI-Express x16 slot. Slot 1.
Next slot down is a PCI-Express x1 slot.
Next slot down is a PCI-Express x16 slot. It is Slot 2.
Next slot down is a PCI-Express x4 slot ]


C) Simple error; Front Panel header pinout.

Front Panel header (JPANEL1) is at the bottom right corner.
Pins 1 through 8 are on the Bottom row;
1, 2, 3, 4, 5, 6, 7, and 8.

Pins 9 through 16 are on the Top row;
9, 10, 11, 12, 13, 14, 15, and 16.

A) Pins 1, 2, 3, and 4 are for an Internal speaker. For BIOS Beep Codes. Pin 1 is for the Positive (+) wire. Pin 4 is for the Negative (-) wire.

B) Pins 5 and 6 are for the HarDDrive activity LED.
Pin 5 is for the Positive (+) wire.

C) Pins 7 and 8 are for a Reset switch, IF a Reset switch is used.

D) Pins 9 and 10 are N/C. Not connected. There is No Pin 11.

E) Pins 12, 13, and 14 are for a dual color Power On LED.
Pins 12 and 13 are for the Positive (+) wires, Pin 14 for the Negative.
If just using a single color Power ON LED, use Pins 12 and 14.

F) Pins 15 and 16 are for the Power On switch.

Make sure the Power On switch is good. Remove the wires, touch a Jewelers flat tipped screwdriver to the two pins - Briefly.

Comes on you have a bad Power On switch.

Do you KNOW that the Power Supply is good? Tested the three main voltages?
(3.3 Volt power rail
5 Volt power rail
12 Volt power rail )

Need to know how post in a Comment.

Just to ask; What is the maximum rated Wattage of the Power Supply, what is the Amperage of the 12 Volt power rail/s, and what is the manufacturer, and model number of the graphics card?

Regards,

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!

NEW BIOSTAR MOTHERBOARD DOES NOT BOOT


Good day sir, let try to test first the power supply, Unplug the power cord, remove the 20 pin (24 pin for the late model) molex power connector from the motherboard, plug in the power cord, get a 2 to 4 inch jumper wire, short the green wire with any of the red or black wire on the molex 20 pin power plug, the result maybe the following:
  1. you will see the power supply fan turn. you power supply is in good order. replug the power supply, and test again.
  2. you will see the fan turn for a few second then stops. you power supply is selective, and may require a different type of motherboard. Get a new one.
  3. you wont see the fan turn at all. get a new one.
If in case you are with #1. uinplug the power cord and remove all the expansion cards, data cables from the hard disk and cd drives. we are trying to isolate the problem. make sure that the only connected cables on the motherboard are as follows:
  1. 20 pin power cable.
  2. 4 pin 12 volt power cable (if applicable)
  3. speaker
  4. power switch
  5. power led
Test the pc once more. plug in the PC. If still the board wont power on. problem with your motherboard. Note:make sure your RAM is good. Hope this helps.

Hi m_o_redz,
If you are using the on-board (integrated video), S3 Graphics Chrome9 HC Integrated Graphics core. Than check you're video cable, video cable connection. Try another monitor. If all check out ok than the MSI integrated video is defective. Suggest you install a PCI-E video card.
If you are using a PCI-E card, try removing it. Clean the copper contacts using a cotton swab & alcohol. (Let it dry) Than reseat the PCI-E card.
Try booting again.

Good Luck!

Is there a power button cable connection adapter for IBM P4 motherboard to Biostar mother board?


if you mean that the power connector is a 3 pin socket connection and the pins on the motherboard are not in line and the middle connector hole is in the way, simply snip with scissors the end connector hole and seperate so you have a 2 pin and a 1 pin and just connect the 2 pin and use as a single connector because you wont need it and connect the 1 pin that you cut away to the other terminal
