Hey guys my wife has this psu that she got about 3 years go and still going strong.. http://www.newegg.com/Product/Product.aspx?Item=N82E16817341016

I wanted to get her a nice card to upgrade from her old 9800GT that is starting to show its age. She will be playing on a 1920x1080 monitor so I was thinking of getting her this card http://www.newegg.com/Product/Product.aspx?Item=N82E16814102913.

She also has a Phenom II x2 550 unlocked to 4 cores and very slightly overclocked. We are not planning on overclocking the gpu at all. Will this PSU be enough to power the system? Would you recommend a different card? I don't want to go over $200. Thank you guys so much again for taking a look and for your responses!

Happy Friday!

Depending how much you stressed that psu, a new psu like that would run it quite fine. 3 years is a long time but I would say you would be good. I might be wrong.

You should be fine. The OCZ PSU you have is pretty decent.

you will be fine with that PSU, normally the Ati card use less power as the nvidia cards so i think you will have no problem. if a GPU has a 500w recommend power supply normally you will still be fine because cards still dont use that much power.

I also really recommend that card its a great card and the sapphire model is also very good. i would have gotten this card myself if i wouldn't have gotten my GTX 560 SSC.

One of my systems has an OC'd Q9550, 4 GB RAM, a GTX260 - a card with similar power requirements to the 6870, a Gigabyte EP45-UD3P motherboard, 3 hard drives and an optical, and a Soundblaster card all powered by a Corsair 750TX.

Running 3 instances of Prime95 to load the CPU and 3DMark06 to load the GPU, it pulls 375 watts from the wall as measured by my Kill-a-Watt meter. Figuring 80% efficiency, the system pulls 300 watts from the PSU.

I would want a somewhat more powerful PSU, but I prefer to operate my power supplies at 50 - 60% load. Oh, wait. 300 watts is 60% of 500 watts. :)

Lol, I take it then that you mean that the psu will be sufficient for that card?
