Re: Motherboard not functioning

If the power supply had a problem then it is likely that the motherboard and/or the CPU got damage from that. I would check the 12V and the 3.3V lines from the PSU.

Without more information I cannot say specifically what the problem is. You can try disconnecting everything from the motherboard except video card, CPU, and RAM to see if it would work that way. If it does then you can start connecting devices until it does not work any more then you have found the problem. If that does not work at all then unplug the video card and RAM see if anything changes (you should get a beep code without the video or RAM). If nothing changes then either the CPU or motherboard is bad and the only way that I know of to find out which one is to either try the CPU in another motherboard or try a different CPU in that motherboard.

What power supply connector will work with the ms8137c motherboard (aka, 20 + 4 pin)

Ahem, you just posted 20 + 4-pin.

That means it can be a 20-pin ATX main power cable, OR a 24-pin ATX main power cable.

Most power supply's now have a 20 + 4-pin power cable.

Use the 20-pin connector, or add the additional 4-pin connector, to make a 24-pin ATX main power cable.


In direct answer to your question, however, it uses a 20-pin ATX main power cable.

For additional questions post in a Comment.

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

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!

How can I find power supply replacement now that is compatible with 661FM-L BOARD?

Your motherboard uses a standard ATX power supply 20 pin power connector. Most ATX power
supplies should be compatible with your board..get a supply rated at 450 watts or higher for
future expansion of your system

Hello there, I got Asus PC-DL Deluxe UAYZ motherboard and would like to connect to ATX 300W 20 pin power supply. Do you think it works, or should i wait till i find 24pin power supply. thanks for your...

This motherboard is designed to be used as a workstation or server. This mother board will need a specific power supply designed for this board as it can use 2 Xeon CPUs. Setting this board with the incorrect power supply will cause the system to not power up or at worse result in damage to the CPU, motherboard, memory, video and other devices including possibly the power supply. I suggest obtaining the proper power supply for this motherboard

The manual for this board states that the motherboard requires a 24 pin ATX power supply that also has an 8 pin 12 volt connector. The manual from ASUS recommends no less then a 300 Watt power supply. I would professionally recommend 500 watts or more if the system will use 2 CPUs and many hard drives in a RAID array.

A suitable power supply can be found here at Newegg

The manual is here at ASUS's support site at

I don't have the manual for 277498-011

As for the Power Supply 99% sure it is an ATX which as long as you get the same Watt as the existing you will be okay. Make sure you look at your existing connectors to see if you have a 24 pin or 20pin motherboard and 4 pin or 8 pin additional power plug (black and yellow wires) and the new power supply has matching connectors....older ATX supplies have only 20 pins, but there are converters from 20 to 24 pin available.

Watch for the new power supplies and your drive connectors as some of the new power supplies have limited ATA plugs...if you have a lot of ATA devices you might need SATA power convertor plugs or ATA splitters to get all you ATA devices up.

The extra 4 pins on the power supply's atx connector is for new motherboards that require 24pin power supplies. If your motherboard has a 20pin port, then only connect the 20pin portion of your power supply connector.

If your power supply has a 24pin fixed connector that can't be split into a 20+4pin configuration, and your motherboard doesn't have space to let the extra 4pins on the side, then you might want to consider returning the power supply and change it for one that can be used as a 20 or 24pin. Otherwise you will need to cut the extra 4pins apart.
