I just got my x1950xt in and I don't have a 6 pin power for the card. I saw an adapter on newegg here - but it's not clear if you should remove the central bottom pin or not - any ideas for this card? And all that said - am I dreaming that my 380 antec supply will be up to the task? The silent PSU review website said the cards don't really need all that power as advertised?

I have an older 600Watt single 12v rail power supply. I just made an adapter out of an old ATX plug. 3 pins on one side are grounds, the other 3 pins are +12v. I believe the spec allows for up to one of those pins on either side to be disconnected, but it shouldn't matter if they aren't. Mine works fine with a single 12v rail connected to all 3 12v points.

The 12v connections are against the PC board and the Ground connections are farthest from the board.

When I made mine I cut a 6 pin segment off the end of a 20 pin ATX connector, due to the keying I had to shave two corner off of one pin, makes a perfect fit and gives you a keyed connection. I used a standard molex 4 pin female connector, and ran the yellow (12v wire to the 3 12v connections on my new 6 pin plug. And ran the 5v and 12v grounds to the 3 ground connections on the 6 pin plug. Also, since this plug has the potential to draw a lot of current be sure to solder all of your connections.

I have read other posts where people had made their own plugs on multi rail power supplies using two molex connectors, and running different rails to different 12v connections on the 6 pin plug. All grounds should be common.

Hope that makes sense, and be aware if you try to make your own plug you might fry your card, motherboard, and / or powersupply.

edit - Also make sure your powersupply can handle the load. Mine supplies 20+ amps on the 12v rail and runs fine.
