PCI Express 6pin power cable layout?

[mpeg4v3]

I was wondering if anyone had the specs for the 6pin PCI Express power cable. I just got an eVGA 7800 GT, and it didn't come with a 6pin power cable. I'm currently at a LAN and, although most 3d games run, they run really poorly with the downclocked core/mem speeds as a result. Because of this, I want to make my own 6pin power cable until I can buy a proper one. I was wondering if anyone knew the exact layout of the cable. From what I've been able to tell on Google images, the bottom row is three 12v cables, while the top row (where the "hook" to attach the connector on the video card) is three ground cables. Is this right? Does anyone else with this video card know the proper layout? I don't want to fry my video card.

I'm sure the lan is over with but it

The part at the bottom is the locking tab

X= Yellow
G= 5v Ground
N= Not connected
B= 12v Ground

Negative, three +12 lines and three ground lines. Can't remember which are on the clip side though
