A suitable Ps/2 PSU to power nvidia gtx 570

Hello all

I want to change the PSU on this Dell XPS8300 because I need to upgrade the graphics card to a GTX570. It's not for gaming but for cycles rendering in Blender,
and working in Poser Pro2012

Two PSUs which will fit (150x86x140) are the Zalman GT 700w 80 plus, or the Silverstone ST 65 F-G (modular).

I am leaning towards the Silverstone because it's modular, but looking on their PDF list, it is not clear if the gtx570 is supported; although they have listed the gtx580.

The Western Digital, in the list below, is in an eSata enclosure and has it's own power source.

Thanks in advance for any relevant advice.

    put all your parts in this and it should tell you the required wattage for the system as far as compatability goes.all PSU's are generally compatible it is more of an issue if you have several GPU's that you dont have enugh wattage and therefore not the required cables with the power supply
