Hi all,

I want to upgrade my computer case to a larger one with a few more fans on it but I am concerned if my PSU is up to scratch. I have tried all the online PSU calculators but I don't trust them as they all have varied results.

What I will be running after the upgrade;

- Gigabyte GA-X58A-UD3R rev 2.0
- Intel i7 930 2.93GHz
- 2x GTX 570 Sli
- 12gb Corsair XMS3 DDR3 Ram
- Thermaltake ISGC-300 Cpu Cooler
- Aerocool X-Predator Case
- Aerocool Touch 2100 Panel Fan Controller
- 6x 140mm fans
- 2x 230mm fans

Nothing is overclocked.
Also installed are general USB Mouse and keyboard with 2 DVD drives.

I currently have a XFX 850W Black Edition PSU installed.

I would just like to know if the current PSU will be adequate or I will need to upgrade.

As I am a graphic designer and as well as a gamer so my computer does sometimes reach full load.

Thanks.
