I cant find any

Is it a consumer desktop computer from a brand like Acer, Dell, Compaq, Gateway, HP, Sony, ...? If it is, please provide the brand and model.

 

[imtiax]

Yes it is Acer. Aspire M5700

Looking at the Aspire M5700 Service Guide shows that it uses a standard ATX (a.k.a. PS2) form factor power supply unit.

The replacement power supply unit, that you buy, does not have to have a fan on the back. The ones with a big fan on one side will have the fan oriented in the proper direction when the power supply is mounted into the case.

Consider the Corsair Builder Series CX500 V2 (CMPSU-500CXV2). It should have enough capacity to handle the addition of a decent discrete graphics card at a later time.

The problem is that the case is so small. Bascially the case is the size of the motherboard.

There is like 0.3mm of space between the bottom of my motherboard and the bottom of my case...They literally touch each other. If i get a psu like that. (My psu is top mounted) it will touch my cpu cooler/fan thing.

The current psu almost already touches it..

This case is really small and I cant switch it into antoher case because it is a propietary motherboard. I tried and it wouldnt work on another case

The Acer Aspire M5700 Series Service Manual specifically states:

Power Supply

Power Supply Mounting Features
• Chassis accepts ATX-style power supply
• Chasses accepts PS2, PS3 style power supply
• Features for internal mounting tab
• Location of 4 external mounting holes

The motherboard adheres to the microATX (a.k.a. mATX or uATX or µATX) form factor (i.e. 244mm x 244mm). The motherboard's mounting holes are all in the standard microATX positions.

The Acer Aspire M5700 Series case is a microATX mini tower.

From what I've seen of the Acer Aspire M5700, its motherboard will fit another case, and a new ATX power supply unit will fit in the Acer Aspire M5700's case with no problems.

It's a properiaty motherboard so the ffront I/O does not work with other cases. I took my computer to canada computers and the tech support were unable to do it

Just because the techs at Canada Computers were unable to do it does not mean it can't be done.

There is documentation available about that motherboard's front panel header, front USB and front audio available to make it work.

 

[imtiax]

I looked at them. I am still un sure of how to do it. The thing is in the current Acer case all those little wires http://www.techexcess.net/images/products/dell/5G841.jpg


And then there are the USB's and audio.

But in another case all those little cables are separate so I am not sure how to do it.

I also took it to BestBuy geek squad today and they were unable to do it.

 

[ko888]

If you were to move that old Acer mATX motherboard to a new case you may/will have to rewire the front panel connector from the new case to match what the motherboard's front panel header expects if the case's front panel connector is a single 20-pin connector.

 

[imtiax]

Yeah that was my problem. The cases front panel connector is a single 20-pin connector.

So i could not figure out how to make it work in the new case as the new case has like tons of seperate wires for the front pin connectors

 

[imtiax]

I looked at my motherboards manual and still no help. Because the labels in the new case do not match the labels in the manual.

Epically the reset switch and those 5v cables. Because this case has no reset switch.


I would pay someone to do this for me but I can't find a store that can.

I wouldn't expect the connector labeling for the new case to match the labels in the manual. Terminology changes over time.

Each motherboard manufacturer and case manufacturer may have different label names for each pin.

If I were to plug in the wrong cable into the wrong pins would it damage my PC when I try to turn it on?

Basically if the PC does not turn on or lights dont work i just try it in another hole? right?

Or am I better off just buying a new mobo for my processor.

Yes it could cause damage, because one wrong connection can cause a short circuit that will melt the case's front panel wiring or even a circuit trace on the motherboard.

Your shotgun approach to wiring should not be attempted unless you don't care if you burn something out.

This might be of some help
Pins 1-9 are the same as on your 14 pin FPC ( refer to the dwg. ko provided )


Pins 11-14 are for IR, your new case have that ?

This is a sound cable, if you have it on your system, forget about front panel sound in your new case



"GeekSquad couldn't do it"
I wouldn't expect them to be able to

 

[imtiax]

See in your diagram. The number 10 is no pin

On my motherboard number 8 is no pin and number 10 has a pin.

On the 14 pin connector ?

 

[imtiax]

I was talking about the front panel connector thing. Like the thing you plug those tiny wires into. For the reset/powerreset, leds, ect.

That's a 14 pin connector, look again at the chart provided by ko, very top , see pins 1-14 ?
The description in your last post is of the audio connector.
If you can't differentiate between them no one is going to be able to help.
