Looking for advice on fitting a video card (basic stuff)

Hi

I have been looking at this website for a few months and as such bought a graphics card based on the recommendations that i found here.

But here is the rub the video care requires an extra cable to draw power from the psu and i have no idea what to do nor am i familiar with technical details

Here are the specifics

7900 gt gigabyte 256mb graphics card with a 4 pin male port at the back which i assume requires a lead to pull my power from the PSU

my system is an;

optiplex 740

Vista Business
Phenon quad core 9600
2 x 250gb hard drives.
PSU 305watts (but it is sustained power not peak power so i am sure that this will be fine)
anything else you need tell me

I bought a 3 way splitter with each with 4 pins one male and two female.

and from this point on i have no idea what to do

I can open the computer and identify most of the components, but when it comes to wires just no idea.

Your thoughts would be appreciated (and maybe pictures if you have any?)

best wishes

It's really hard to mess it up as the adapter will only fit one way and to one connection.

Ok i have found out exactly what i need i have a sata PSU and the graphics card is a 4 pin molex. so i need a 15 pin male sata to 4 pin female molex adapter.

Guess what it is impossible to find in the UK the only place i can find them in America.

But the search will have to go on.

hey mtyermom

No what i said was true. the sata PSU has no 4 pin molex so i bought an adapter from the only place i could find in the UK. 15 pin male sata to 4pin female molex

problem finally solved

fx 5200
to a
7900 gt

fantastic difference
