PCI-E supplementary power query!!

Just bought an XFX Nvidia 7900GT GFX card... Looks good, its heavy AND it needs power, not like my old 6600GT..

The power cable supplied has a 6 pin plug with pins like this ::: and the usual 4 pin legacy power plug.

As my motherboard is about a year old, that means its OLD, it doesn't have PCI-E supplementary power on the board.

As the GFX card has a Legacy power socket on it, would it be perfectly ok for me to plug in a normal Legacy power plug to power it???

Or do i need to get another motherboard with PCI-E power on it??

Many Thanks

Rob

Actually it's your PSU that is old. You may want to upgrade your PSU with one that has the PCI-e power connector.

If you've got one of these cards then it's fine to plug in the old 4 pin molex cable. They're fine for powering video cards. Most PCI-Express video cards come with 6 pin PCI-Express connectors but either will work properly. They both do the same thing: provide 12 volts to the video card.

By the way, despite being way faster, your 7900 GT uses about the same amount of power as a 6600 GT.
