Help! What are these six connectors next to ATX power on motherboard?

[Kwad Guy]

I have a motherboard that I can't seem to get to boot or
even power up.

It's got a standard 2x10 pin ATX connector. But right
next to that, it's got a 6 pin (not 2 x 6, just 6)
connector that appears it might be some other sort of
power connector...Anyone know what this might be?

There are also two pins labeled "standby", which I
guess must be standby power...Hmmm...What's the deal
here. The other motherboards I've used have never
required anything more than the standard ATX power
connector...

Thanks,

Kwad

Well, can't say that I'm sure about this but it seems like the mobo needs power from the new ATX standard or what ever it's called. I remember some other people in here were talking about the exact same subject. The new ATX PSUs has a normal 2x10 connector and with that an extra connector, but I don't remember weather it was 1x6 or something else.

Hopefully others will respond to this, but it seems like you need a new PSU

It's an additional power connector, dang cpu's and video cards want more power. My PSU has an addition connector on it, but my mom board doesn't need it.

Well, I had a serverboard that required two sets of power connectors, one the standard atx, and the other two were a 5v 5 pin connection. One of the 5pin deals was next to the normal atx connector, and the other was at the base of the board Required a special powersupply that was nearly 150 new. So I just sold it to someone else. And as a guess, it could also be the older boards that had both the ATX and the AT style board. If that is the case, many require you to set a jumper on the board to tell it to use one or the other. If set wrong, then it won't boot/post/or anything. Does it look like a single row of metal pins with a wall of plastic at one side?

The ATX spec describes a 6 pin auxiliary power connector with the pin out:

1 com black
2 com black
3 com black
4 3.3V Green
5 3.3V Green
6 5V Red

the color would be the wire color on the connector from the PS if you had it.
The PDF here will tell you everything about ATX PSs.

Tsaico:

You described it exactly...A single row of (6) metal pins with a wall
of plastic behind it...

It sounds like this is a aux power connector. Can I just tap
that off the regular ATX power supply with a simple adaptor? If
so, where would I get an adaptor (and please let it be
reasonably priced!)

It's an Auxilliary server connection.

Your PSU needs it.

My 450 watt power win has one, my incoming Enermax has one as well.

Enermax EG351P/EG451P page

Look at the very bottom of the page there are pictures of all the connectors.

The one on the far left is the Pentium4 connector, the 2nd one from the left is the Auxillary power for Server boards. See if that's what you mean.

If it is, then you need a new supply for it, sorry

On the upside the 330watt enermax is only $75 canadian (~$50US), and the 430W is $125cdn ($83US)

It sounds to me like the board is has dual support for ATX and AT powersupplies. Is the keyboard a big socket at the top of the board facing out or a PS/2? If the keyboard is a large one, then you definitly have a AT board and if you get the right case/powersupply, then you should be ready to go. Also, you need to install all the ports (serial, mouse ps/2, parallel, usually on the little plates that fit in the slots on the back of the case) seperately on AT boards, whereas atx all have them already attached and soldered on.
