Hey guys, as I wrote in a previous thread I have plans on buying a new GFX when I go to Italy next month, now I have plans on buying a 285GTX but I am not sure if my PSU will be powerful enough. So I hope some of you here in the computer forum might be able tell me that.

My current system looks like this:

Intel Q9550 Quadcore 2.8ghz + XIGMATEK Achilles CPU Cooler
4x2GB = 8GB DDR-2 Dual Channel 800Mhz RAM
NForce 650i SLI Motherboard
1x500GB (Some western digigal HDD)

I believe there is 2 case fans aswell, and some lights in and around my case.

The current GFX I have is a GeForce 8800GT 512MB Ram, I have been up til now using 2x GeForce 8800GT 512MB running SLI, but one of them has now a RAM error and my 1 year warrenty on the computer is out. So now is a good time to upgrade anyway.

When I buy the 285GTX I was hoping I could use the GTX as my main card obviously and then have the 8800GT as dedicated PhysX card, But here is the question:

Will my current 750W PSU be enought to handle that considering my hardware. I know I ran 2x8800SLI without any problems, im just wondering aobut the GTX+8800GT

Thanks for your help guys.

You should be fine.

If you buy it, and your system is not starting then you can easily replace the PSU.

But 750 watts is plenty.
