It depends on what motherboard, processor and ROMs you're running.

This should work fine:  http://www.newegg.com/Product/Product.aspx?Item=N82E16814121657

It has a max draw of 75w, but typically won't draw near as much as that, and even at that load, a 280w supply should be fine if it's just powering a basic PC with one hard drive and 16GB of RAM.

The PC has an 17 processor, but it came with a 1GB Radeon card.

What generation i7?   i.e. what's the model #??

Simple fact is if it's already got a 1GB Radeon card installed, it's virtually certain you can use a 2GB version of the SAME Radeon GPU ... NOT a higher-end card that would require more power.

e.g. if it's got a 1GB Radeon 6450, you can use the 2GB version I suggested above;  if it's got a 1GB version of another Radeon GPU, use the 2GB version of that GPU.    No system is going to be designed so close to the limit that an extra 1GB of video RAM is going to "push it over" the power supply's capabilities -)

As a matter of interest, why do you need a 2GB card?    A 1GB should be fine for just about any application.

Hmm ... I don't see a 2GB version of  that card.

Note also that it's a relatively low-end card.

"... That was the client request. I don't think they need it but.... "  ==>  Do your client (and your reputation) a favor and tell your client that a 2GB card that will work with that system's power supply is NOT going to have any better performance than the card he's already got [It's about a wash ... the 7450 scores 317 on PassMark's G3DMark; the 6450 scores 293].

I think what your client REALLY wants is a card that will perform better ... and for that he doesn't need more video memory, but a higher-performance GPU.   For that, he needs not only the card, but also a new PSU with higher output capacity.

Point taken but at this stage I have to give him a 2GB or not get paid so I will most likely go with your suggestion on the Asus Card
