Hi all, I have an older card i wanted to install, its an AIT radeon x1300 agp. Here is a picture of the exact card i have...
 
i was wondering if you can tell from the pic if it needs a power cable plugged in. it has some PRONGS on it in the CORNER on the right hand side of that pic, but the power cable from the hard drive for example wont fit into it, and when i install it and boot up my pc, the monitor never comes on at all. it looks like the power wire that goes from the power SUPPLY to the floppy drive might fit the input on the card tho, should i just TRY it?I can't say for sure that those pins are a power connection but it seems so.  This may help: http://www.computing.net/answers/hardware/additional-power-connector-on-agp/49655.html

Apparently, some video cards do use that type of power connector, although most used a standard molex connector of the type used for hard drives or a newer 6-pin connector.  Those  types are shown here: http://www.wikihow.com/Connect-a-Video-Card-Power-CableIt's a floppy power connector.
Strange that a card like that needs the extra power though, as it's quite low-end.thanks guys i really appreciate it! i will try to get this going tonight! i tried looking around google but i was getting stumped. again much appreciated!
