Question about ASUS P7H55M PRO (90MIBBB0G0EAY0KZ) Motherboard

Open Question

I purchased the P7H55 motherboard installed it into my case. The only way I can get any power was to not plug in the EATX12V by not plugging in this power connector I was able to get the fans to spin. But, I cannot get any power to my keyboard, mouse, or monitor. The monitor goes light turns amber and the system POST does not start because the BIOS does not beep. I have a 550watt power supply, 2GB memory, and 1TB hard drive connected. HELP

Hi,
From the description of the problem, it seems that either the power switch of your PC or the power supply cable is faulty. Also, please let us know if the motherboard LED is glowing or not. Do reply for more assistance.

Thanks.

Have you tried resetting the bios? turn off the computer and remove the power cable connected to the power ATX power supply, look for the "clr_cmos" jumper and change the settings from 1-2 to 2-3 for approx. 10 secs, then return the jumpers to original settings and reconnnect the power cable and turn on the computer. This was the solution when i had the same problem before. Hope this helps you too.

P6TD fusible resitor blown near memory P0207?


What a minute hold the phone here!

Those are Ferrite Iron Choke Coils.

The 'little round cans' with the Red(?) edge on top, are Solid Polymer Capacitors, going around the processor socket.

Those are Ferrite Choke Coils going around the top side of the processor socket, immediately near the copper heat pipe fins. (Black/Square shaped top, rectangular shaped body)

The choke coils, and solid capacitors are part of the Motherboard Voltage Regulator Circuit. These particular ones are for the processor.

The ones down by the Ram Memory slots are also in the Motherboard Voltage Regulator Circuit.

May be for the Ram Memory slots, but easily could also be for the expansion slots, too. (PCI-E x16, PCI-E x1, PCI, etc)

Here is more info on the Motherboard Voltage Regulator Circuit,

http://www.hardwaresecrets.com/article/616

So; Are you using the correct voltage ram memory, or have you installed 'performance stuff', and had to change voltage in BIOS Setup?

More importantly,
1) Are you running a graphics card?
2) More than one?
3) Have the proper amount of power, (Wattage and 12 Volt power rail/s)
4) Proper power cables from Power Supply?

4) Same thing for the motherboard;
IF, you are using a Processor that requires a LOT of Wattage, and you are using a graphics card; are you plugging in an 8-pin EPS +12 Volt power cable into the motherboard?

The 8-pin EPS +12 Volt power cable connector, is called an EATX12V power cable connector by Asus. It's up at the top edge of the motherboard, above the top left corner of the processor socket.

Called EATX12V to keep people from confusing it with this power cable,

http://www.hardwaresecrets.com/article/616

They are NOT the same;
EATX12V, or EPS +12 Volt power cable; has FOUR Yellow wires.
A Yellow insulated wire is a 12 Volt wire. Black wires are Ground wires.

An 8-pin PCI Express power cable has THREE Yellow wires, and FIVE Black wires.

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

BOTH, a 4-pin ATX +12 Volt power cable, and an 8-pin EPS +12 Volt power cable; are power for the PROCESSOR.

Quad-Core, or a processor that uses this much power? 8-pin EPS +12 Volt power cable.

The MAXIMUM amount of Wattage a PCI-Express x16 slot can deliver is 75 Watts.
EACH 6-pin PCI Express power cable is capable of delivering 75 Watts.
Total of 150 Watts available for a graphics card.

An 8-pin PCI Express power cable is capable of delivering 150 Watts by itself.

Point?
Use the correct power cable IF needed for the graphics card, and the correct number of them if two are required.

Also; IF you did not have the correct power cables; AND used a power adapter cable, USE all of the required 4-pin Peripheral power cables needed, for that power adapter cable.

For example;
I have noted those who did not have TWO 4-pin Peripheral power cables, required for a 6-pin PCI Express adapter power cable.
Just one was available, and just one was used.........

!O_O!
Nope!
This will result in;
1) PCI Express x16 slot contact pins - Burn
2) Gold plated contact pins on bottom of PCI-Express graphics card -Burn
3) 6-pin PCI Express power cable connection on graphics card - Burns
4) Contact pins in connector for 6-pin PCI Express power cable - Burns

That to me could also result in damage to electronic components, in the Motherboard Voltage Regulator Circuit;

Hence -> Ferrite Iron Choke Coils

Awaiting your response,

Regards,

Asus p7h55-m black screen when i installed video card.. then i thought my video card is not functioning.. i get it and use on board vga.. its the same problem.. black screen, keyboard no light.. no si


Have you tried removing the new video card? Try that first.
The fact that your keyboard doesn't light most likely means that either your power supply is being pulled down by the video card or is now gone. Was your power supply rated high enough wattage for your computer with the new video card? If the video card was higher-end then it's possible that it killed the supply.
It could also be the motherboard that's gone. Static discharge when putting the video card in, or a bad video card can destroy a motherboard.

Make sure you have the VGA cable plugged into the video card if you have one. Also, make sure you have the 24 pin power connector connected to the motherboard as well as the 12v rail (should be a 4 or 8 pin connector that plugs in to the top right of the motherboard when looking at it right side up.
Good luck!

did you check to see if there is a connection not plugged in or a jumper setting causing the conflict. also depending on what your using the pc for (especially graphics) you might want to install a video card.

The P7H55-M motherboard has on-board audio and connections to the audio on the rear connections including a S/PDIF connector. If you want to install a soundcard then you should first disable the on-board audio controller in the Bios.

Powering up


You need to remove the cap from 8-pin EATX12V connector and connect 8-pin EPC +12V power plug from your P/S, otherwise it will not work. Your power supply should support 8-pin EATX12V. If you P/S comes with 4-pin connector only you just use your 4-pin open spot and leave the cap on.
