Hey guys,

I'm trying to upgrade to a good graphics card that can basically run newly released games optimally with pretty high settings.

I'm also trying to minimize costs, which would mean not buying a new power supply.

Anyways, I'm trying to look for the best gaming graphics card supported by 400W (Yes, I'm already aware that there are few)

I'm currently looking at the GTX Ti 550 which seems like a decent card and is supported with 400W.
By the way, my resolution is 1600x900. I have 4 GB Ram and am AMD Athlon II x4 (quad core) processor 2.80 GHz

Any help is very much appreciated :)

IMHO, there are few mistakes one can make more significant than cutting corners on a PSU. Think of it as an insurance policy.

What kind of PSU?

If you have a good 400 watt power supply (28 - 30 amps on the 12 volt rail), the 6850 should be a good choice.

Figure 10 amps (120 watts) for the video card, 10 amps (another 120 watts) for the CPU, and 100 watts for the motherboard, RAM, and a couple of drives.

One of my systems has an OC'd Q9550, 4 GB RAM of DDR2 RAM, a GTX260 - a card pulls about 30 watts more when under load, 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% PSU efficiency, the system pulls 300 watts from the PSU.

Do you know how I can see how good my power supply is besides the Watts?

^and at the same time, I don't want to take any chances. I want to know that it will FOR SURE run with 400w.

Bump? If you guys can't think of one, would you say that the GTX Ti 550 is a solid choice?

Give us the exactly PSU model, so we can look for 12v rail amperage.

You can look your PSU model after you open your left side case. You should tell us the Amp for 12V.

Ok well I found the box and under +12V1 it says 14A and under +12V2 it says 15A I don't know if that's what your looking for though.

Yup, thats what we need. I think your PSU can handle card. But, what is the model of that PSU?
