[SOLVED] Compatible ASUS Motherboard

[Britton30]

Chipsets also may have some SATA and USB controllers too or a GPU if the board has onboard graphics.

Hi everyone, it's me again with a question about a replacement motherboard I bought. I opted to go with the GIGABYTE GA-G41MT-S2PT LGA 775 Intel G41 + ICH7 Micro ATX Intel Motherboard to replace the Asus p5ql-vm epu/cm5570/dp_mb.

I have ran into a snag, the front panel connector pins on the motherboard are different. For sake of clarity I will post pictures.

This is the old ASUS MB.


This is the new GIGABYTE MB.

This is the 20 pin front panel connector.


On the old MB there is several pins missing as compared to the new MB. So, my question is what do I do? I'm lost at this point.


Thanks in advance and sorry to be a pain, NJ

Your probably going to have to pull the terminals out of the plastic socket trace them back to the switch and leds then hook them up individually.
The 2 power switch wires are not polarity sensitive and go to the PWR +/- pins, the power led(PWR_LED +/-) is polarity sensitive it will only light up if hooked up correctly, however hooking it up wrong will not hurt anything so try it one way if inop swap the wires, There may not be a case speaker if there is there are 2 wires polarity doesn't matter.

What else do the wires run to? Is there a reset switch?

 

[N_J]

The wires run to the power switch and power LED. No reset switch.

I don't quite understand your instructions. One other thing on the connector from the front power switch that connects to the MB. It won't plug in because of one pin on the new MB, which would be on the bottom row third pin from the left. On the old MB that pin is not there.

You have to remove the wires from the black plastic plug and hook them up one at a time, The OEM Acer board may or may not use the same pin layout.

Will it hurt anything if they are wrong? And do I need to clip the pin that is obstructing the connector from engaging to the MB?

 

[Wrench97]

You need to trace the wires back to figure out which wire goes to what on the case.

if you are plugging the wires in individually without the back plastic connector how is the pin going to be in the way?

I never thought of plugging in the wires individually without the black plastic connector....ingenious!

However, I'm still somewhat stumped on the wiring and really don't want to fry something. I found the wiring diagrams for both boards and am attaching them in the hopes you can help me.

This is the original ASUS f_panel diagram.

and....

this is the new Gigabyte f_panel diagram.

I appreciate your help and patience with me.

The power switch and reset switch the polarity(+ or -) makes no difference the switches are just momentary connections like a door bell button the switch only connects the 2 together while it's being pushed.

The led lights will only work if the + / - is wired to the right pin, if it's backwards that led will not light is all that can happen nothing will short or be damaged you'll just need to swap the 2 wires to make the light work.

The PLED on the new board is the power light(Message/Power/Sleep) on the old board.

IDE_LED is the hard drive Activity light.

The 2 pins labeled ground in between the 2 speaker wires do not get hooked to anything.

Don't worry about the Chassis Intrusion Header if it has wires there leave them disconnected.

i hope he does get windows 8 that is an awesome os. has annoying features but its a awesome os nonetheless.

UPDATE: Wrench97, your wiring instructions was spot on. Thank you so much!

throttleboi.....we went with Windows 7 Ultimate.



This topic can now be closed and a BIG thank you to everyone who helped.
