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
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.
Now I just to be sure that my power supply can handle it, which I'm pretty sure it can. 400W, +12V1 it says 14A and under +12V2 it says 15A and the link of the PSU can be found http://www.futureshop.ca/en-CA/pro [...] 23c0afen02
Can anyone confirm that my Power Supply can support this card?
