Standby 5V overvoltage (8-9 volts instead of 5): what's probably damaged?


  • Check the voltage on the Power supply. (5V STB is on pin no. 9).
  • Check the voltage (on pin no. 9) from the back of the motherboard on ATX socket.
  • Check the voltages on the Front Panel connector for 3.3v, 5v and ground.
  • Check for shorting by placing one probe of multimeter on the ground and the other one by one in pin no. 1,2, 4, 6, 8,9,10,11,12,14,19,20 also on the CPU connector. If there is shorting the problem is with some component on the motherboard.
I think probably the Power Supply (SMPS) is faulty.

Hope that helps.

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?

Mercury Motherboard PI845GLM-L manual needed for wire connections... please help me


If my information is correct;

Orient the motherboard so that we are both looking at it in the same direction,
Processor to the top, Ram Memory slots to the right, white PCI slots to the bottom.

The front plastic panel of your computer that has the Power On button, Harddrive activity LED light, and Power On LED light, is the Front Panel.

The area of pins on the motherboard, that the wires from the Front Panel go to, is the Front Panel header.

The Front Panel header is all the way down on the right corner. Panel 1.

The Front Panel header, or Panel 1, is a rectangular block that is positioned lengthwise, across the bottom of the motherboard.

There are 4 pins across the Top, and 5 pins across the Bottom.

The pins are numbered.
They are numbered Even across the Top row.
Pins 2, 4, 6, and 8. (There is NO Pin 10. Just a blank spot)

They are numbered Odd across the Bottom row.
Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED light. (HDD LED)
Pin 1 is for the Positive wire. ( + )
{ Pin 2 is for the Negative wire. ( - ) }

If the LED light is dim when operating, turn the wires around.

B) Pins 5 and 7 are for a Reset switch, (Reset button), IF a Reset switch is used.
Pin 5 is for the Negative wire

C) Pin 9 is RVSD_DNU
Reserved Do Not Use.

D) Pins 2 and 4 are for the Power On LED light.
Pin 2 is for the Positive ( + ) wire.

If the LED light is dim turn the wires around.

E) Pins 6 and 8 are for the Power On switch.

For additional questions please post in a Comment.

Front panel header pin connections how to put the pin in the right place because i put my motherboard in a differen case can u send be a picture so i can know how to do it sony rx660


Don't quote me on this pinout ladydj11, but I believe this is correct;

The Front panel header is located parallel to the Bottom Right edge of the motherboard.
(Motherboard orientation; Processor to the top, Ram Memory slots to the right, PCI slots to the bottom)

There are two rows of 10 pins laid out horizontally. (20 pins total)

I will number the pins for easier orientation.

Starting from the Left side of the motherboard going towards the Right, across the Top;

Pins 1, 3, 5,. 7, 9, 11, 13, 15, 17, and 19.

Starting from the Left side of the motherboard going towards the Right, across the Bottom;

Pins 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20.

A) Pins 1 and 5 are for the Power On LED light.
(Pins 1, 3, and 5 would be used for a dual color Power On LED light. Pins 1 and 3 are for the Positive { + } wire)

B) Pins 7 and 9 are for a Keyboard Lock. Believe the pins are left unconnected for an unlock status.

[ May be the other way around. The two pins may be have to be connected, in order to complete a circuit which allows power to go through the Keylock switch, when it is in the locked position ]


C) Pins 13, 15, 17, and 19 are for an internal speaker. Used for BIOS Beep Codes.

D) Pins 12 and 14 are for the Power On switch

E) Pins 16 and 18 are for a Reset switch, IF used.

Power switch


When looking at the motherboard, position yourself so that the RAM slots are running vertically on the right side of the board. The PCI and AGP slots should be running horizontally on the lower left side of the board.

In the bottom right of the board, you will see a block that has 9 pins, a row of 4 on the top and a row of 5 on the bottom.

The middle pins, one above the other, are the power button connectors. Insert your PWRBTN# on the top and the GND wire onto the botton pin.

Hmmm.... mainly you have:
-20 or 24-pins connector, that is unique and goes directly to motherboard (powers motherboard and its components)
-4 or 8-pins connector that powers CPU
-the rest would be connectors for ROM (CD/DVD/BlueRay) and HDD devices (there are: molex and sata power conectors)

If you totaly unshure, there is manual:

No power and I need wiring diagram for jumpers


Hi !

Via VT8237R is a chip that is on your motherboard. It does not determine your motherboard, and this chip is used in many different motherboards and producers of motherboards.

Try to locate the model and producer of your motherboard.

Usually it is written between PCI SLOTS or close to the RAM slots or close to the VGA Slot.

Finally, there is also possible to find a diagram written on the motherboard or close to the pins, with description of +/- pins.

Regards.
