The power supply in your PC is only 250W.
That means means the best you can do in your PC is a Radeon HD 4350 or a Radeon HD 6450.
You cannot install a video card that requires additional power via an auxiliary connector without first upgrading the power supply (unless you want to see a lot of smoke).
GDDR5 video memory just communicates with the GPU on the video adapter, and should have no effect regarding compatiblity with the rest of your PC.

I think that might be pushing the P/S beyond its limits.
The recommended P/S for that card is 400W.
I put this HIS 6570 card in my HP 8200 Elite CMT which has a 325W P/S, and it works just great. No problems whatsoever.
Also, HP lists a Radeon HD 6570 as an optional card for my PC, so I wasn't too concerned about my P/S being 75W shy of the recommended video card wattage specs.
But mine has 75 more watts of power than yours, and that could make a big difference.
You can try it but...

It is fine to ask questions.
Your P/S has to be able to power all of the hardware within its specified rating.
Now, just because the manufacturer says the recommended wattage of the P/S for card is 500W, does not mean the card is gonna use 500W (no where near that--Maybe 100W tops).
They want to play it safe so that when you take all of the hardware into account, video, processor, HDD, DVD burner, memory, etc, that the P/S will be able to handle all of that hardware.
I have a link to a cool P/S calculator. You can input a lot of parameters, and it will tell you what size (Wattage) P/S you need.
When I run the calculator with my setup and the Radeon HD 6570, it says I need a 297W power supply, so I guess I am fine according to that (my 325W P/S)
