Ok lets put this in perspective, my x850xt eats up more power then his and it can run on that same PSU fine. You should be fine, try it out and see how well it works, if not all you need is a good 450watt power supply.

Well, the PSU i have does have an available six pin power connector, but this car uses a Floppy disk power connector. If I need something more, I will be looking into a 450 or 500 Watt Antec. This one I have now should be sufficient enough.

A x800 does not draw more power than a x1600pro...they are almost identical cards. Both run around 500mhz core and 1.1-1.2ghz for the mem speed, both are 128 bit cards. My guess is that the x1600 still pulls more power, due to its newer design...as ATI rarely goes down in power consumption.

*If you want to know for sure, please list the amperage off of the side of the PSU.

amperage*voltage = watts

If the PSU is capable of 350w total ouput, then you could pull [350w * 75%] = 262W before you start really straining the PSU. If its a crappy PSU, it will start straining with that load long before the 75% margin is crossed. Also...do you plan on OC'ing the GPU at all?

I dont doubt that it will work, just that its not a good idea to make it work. Your so close to the 'edge' of what that psu is capable of, you are just asking for something to go wrong.

Your current psu is fine. You dont need to buy a new one unless this one for some reason fails. And the x850 was very power hungry, more so then a x1600.
