hi
i have buy this mainboad but she have atx connector , power suply ,
with 24 pin
my thermaltake purepower butterfly 480 watts have only 20 pin (+4 pin
12v)
can i connect this power supply with 20 pin ?? for all use of my
mainboard
and how ?? image ?

my configuration :

intel p4 540 sock lga775 (3,2ghz)
asus p5ad2 premium

The 20 pin connector from the power supply will fit in the 24 pin
connector on the mother board only one way. 4 pins will not be
connected. The separate 4 pin connector from the power supply will
connect to the 4 pin connector on the mother board.

The connectors fit together when they are "right justified"
as shown in the figure below. They only fit one way, if all
20 pins of the smaller connector are to fit the 24 pin
motherboard connector. The "tabs" don't line up, and that
is the only flaw in this scheme. Pin 1 goes to pin 1.

sure my graphic card run ok ???
no power supply directly in my graphic card ??

It is difficult to get any info for this product. I found
information on the AGP version of the card, and that card
has an Aux power connector. These power numbers would be
representative of the overall power consumption of the card.
It is the only info I have to go on.

Here is the AGP info:

http://www.xbitlabs.com/misc/picture/?src=/images/video/ati-powercons/t1.gif&1=1
http://www.xbitlabs.com/articles/video/display/ati-powercons_4.html
Aux power = ([email protected],[email protected])
AGP power = ([email protected], [email protected], [email protected])

With the PCI Express connector as the only way to route the power,
then the Express needs [email protected] , [email protected] , [email protected] amps.

If you use a 20 pin ATX power plug, all of the non-processor +12V
current goes through the single +12V pin on the ATX 20 pin
connector. This is my best guess as to how it is routed.


PSU --------- ATX 20pin +12V --------+--------- PCI Express power pins
|
|______X__X__X Fan headers

PSU --------- ATX 2x2pin +12V ------- Vcore ------ Processor

If the PCI Express version of the ATI card is still drawing
3.42 amps and the fans on the motherboard draw another 1 amp,
that is 4.42 amps. The single +12V pin on the ATX 20pin connector
is good for 6.0 amps. So, as near as I can tell, this one is
safe.

But realize, I am going on little information here, so this is
my best guess. If you find the video card has any instability,
either find a 20 to 24 pin adapter cable (which means a single
wire from the ATX PSU, ends up feeding two pins on the 24 pin
power connector, so at least the pins themselves are in no
danger), or find a power supply with the 24 pin EATX connector
on the end.

When I search in Google, I see mention of some driver issues
with the Asus card. So, you may have trouble deciding whether
any problems that arise are caused by software or hardware.

Have you considered phoning Asus tech support, and asking
them how much power the card requires and whether a 20pin
power supply is OK ? They designed the products, and so
they should know the answer. If this was my system, I would
just measure the current, but that is not a very convenient
solution. The necessary information should be made public.

HTH,
Paul
