M571 motherboard using ATX, can't find power lead for power supply 2

[Damien111]

I have an M571 motherboard which is both AT and ATX. I cannot locate the pins to hook up the lead from my power supply for ATX power, therefore the power supply will not come on. Any ideas?

This particular board and its manual do not show where the two power pins are located.

Near the bottom left, there is no obvious place for the PWR connector.

I would recommend testing the rest of the pins in that area. Have the power supply on and using a flat head screw driver, touch some of the pins until the machine comes to life. ~Apex1x

Actually, I should have said is there a jumper that causes the board to pull power from the ATX connection. The ATX connector is connected, but no power is getting to the power supply. I have a connector that is for use with P4's, but will not use that since the PC is neither a P4 or has the connector for it. The Power supply is an Eagle DR-A300ATX.

Thanks again,

First off, I've only heard bad things about PCChips Motherboards. Looking at their hokey website I don't feel overly confident about them either.

Anyway, have you just upgraded your power supply from AT to ATX? It looks like you need an adapter card to make the mobo work as an ATX:

Frankly, I've never heard of an AT/ATX motherboard until now.

I had an LMR571 and on the box it was marked as an AT board, also all the plugs for the back of the case were housed in brackets to fit an AT style case. Very old board now and ATX wasent long on the scene when this board was about. If your unsure....Dont do it!

Okay--I hope that this helps you a bit!
#1 Yes, there is a jumper that you change. Darn it, though, I don't recall what it is off the top of my head. Let me do some digging (I think I still have one of these boards at home that is properly configured (but dead)
#2 Yeah, there is an ATX form card available for the board, but you don't need it. It is strictly so that you can have a PS/2 port, IR port, and USB ports.
#3 It is made to fit an AT form case--but you can still use an ATX power supply. (on mine, I needed a little crappy computer for a print/file server, so I used an ATX power supply since that is what I had). If you are using an AT case, but putting an ATX power supply into it, then don't forget that you will have to rig up a momentary contact switch to use for your power button. In an AT case, the easiest thing to do is (usually) to use the reset button. Mudskipper

I may have mis-spoken. The manuals don't specify a jumper to tell it to use the ATX power (but I was pretty sure that I had to do this). I'll double check.

As for your power button (momentary contact switch), it goes on 4 & 5 of J1.

If you have decent speed, you can check

If not, then I will try to describe it as best I can.

Orient the motherboard so that it is laying flat. Now rotate the motherboard so that the keyboard connector and all of the slots are furthest away from you. This will put the CPU closest to you, and the RAM slots on the right hand side.

Now look at the left hand side of the motherboard. You will see the BIOS chip and the IDE connectors. J1 is in between them. If you look at the BIOS chip and trail your finger down, the first two pins that you come to (on J1) are pins 1 & 2. The empty space on J1 is pin 3. The last two pins are 4 & 5.

I hope that this helps!! Mudskipper

Okay, it looks like I did give you a bit of wrong info. On my board, I do not have any jumper changed. I had the ATX power supply plugged in, and the power switch was plugged into 4&5 on J1.

Did this work for you? Mudskipper
