1950xtx power supply or connector??/////////

[xtera]

Hi I just bought a 1950xtx and asus P5NSLI. i I can post with one power
supply and play games fine . I am using a dongle and when I use one dongle
that pins on bottom I see i have 2 positive 12 volts and 4 ground on the
molex. . I can post fine when I use the one of the dongles comming from the
adapter. . It only turns on when i use the one dongle on the pci-express
adapter. My existing power supply has 20 pin atx mobo connector and 4 pin
for the mobo my rails for 12 volt are 19 amps 3.3v 35amps +5v 45amps -5v
0.5amps -12v has 0.8amps this is a 580watt power supply . i can post fine
and play games . But im using a 20pin and mobo has a 24pin . Ive tried
another power supply but it would not even start with it but other supply
has less amps in its rails . Im only using one 12volt rail to vcard I see
two rails but im only able to post with one. when i use the 20pin for mobo
and the one rail 12volt to vcard i can post in windows everything is normal.
but it reboots sometimes when im it boots only with one rail to 1950xtx not
two .

According to Anandtech, the X1950XTX draws as much power as the X1900XT
under full load: http://www.anandtech.com/video/showdoc.aspx?i=2821&p=13

On 12V, the X1900XT draws about 4 A through the PCIe slot and 6 A through
the 6-pin connector, according to this article:

If the mobo has a 24-pin receptacle and your PSU has a 20-pin connector, I
suggest you don't just plug it in and leave the 4 pins vacant. Many other
Asus boards allow this because they have a 4-pin Molex receptacle (so-called
EZPlug) near the PCIe slots. The P5NSLI doesn't have it, so buy a cheap
20-to-24-pin adapter patch cord.

I guess these really suck with generic brands . Visited ati and they show
the certified powersupplies for 1950 series and other series . I bought the
thermatake from list and now it works with pci-e 6 pin molex pci e adapter
and tested again with 3dmark 06 this time I was able to get through all the
test with reboots. System now stable. i just turned it off for day and
bought the supply today paid 99 plus 9 bucks tax. so came to be like 109
took the other supply back and got my 60 dollars credit toward the
thermatake . My 3rd pc and this one is my overvall best in quality. I
benched in at 4th place in 3dmark 06 with top scores .
