Thanks all, but now I've found I need a new powersupply because the one I
bought 6 month ago (it was growling badly - annoyingly) was a ATX 1 (20) pin
and the new board is a Biostar MCP6PB M2 with a ATX 24 pin.
I asked about the power supply when I bought the board and the tech guy said
"Sure no problem, your old ATX supply will work". @!%$**. I should have
opened the box and looked at the board!


A 20 pin connector can be used on a 24 pin motherboard. The most important
thing the 24 pin PSU connector adds, is one more wire to carry +12V to the
motherboard. And that power source if used by PCI Express video cards. If
you have two PCI Express video cards installed, and the total consumption
of the cards is 6A or above, then you'd want a real 24 pin power supply.
If you're using one video card (or are using built-in graphics in the
Northbridge), the video card has limits on slot power, that mean the
6A rating of the 20 pin connector is sufficient.

To use your 20 pin power supply, you plug it in like this.

I see your motherboard only has room for one PCI Express video card,
so your 20 pin supply should be OK. It looks like this board uses
a 6150 and has a VGA connector. So your 12V loading on the single
12V yellow wire on the 20 pin connector should be relatively light.

Be aware that your motherboard may not have the most powerful
Vcore regulator. If you look at the CPUSupport tab on that web
page, no processors over 95W are supported. That means, if you
get the urge to upgrade to the most power hungry quad processor
that money can buy (140W), it won't be a good candidate for that
motherboard. For a lot of the 65 watt processors, your new board
should be fine.

One other tiny point about Biostar boards. A while back, when
the ATX12V 2x2 power connector came out, Biostar were connecting
the two yellow wires on that, to the one yellow wire on the main
20 pin connector. I don't consider that to be very smart. If I was
buying a Biostar, just out of curiosity I'd be connecting my
multimeter and doing an ohms test between the two connectors on
the motherboard, to see if they're still continuing with that
practice. I don't know of any other brands that do it.

My main concern with that, is the following. Say a Biostar
customer forgets to plug in the square ATX12V 2x2 power
connector. All the 12V power for both the video card and
the processor, ends up flowing through the main power
connector. Even if you used a 24 pin connector, there
is a danger of exceeding the current rating. So for a
Biostar motherboard user, it is extra important to make
sure the 2x2 connector is installed. (I learned of this
issue with Biostar boards one day, when someone said
their computer was running just fine, and they had this
left over 2x2 connector, and what should they do with it :-)
That is how I could tell the processor power was coming
from the wrong connector.) Make sure both power
connectors are plugged in, before you turn on your
new Biostar.

Thanks for the info Paul but the 20 pin plug on the supply just does not
physically fit.
