Hello,

My son got himself a 7010 via his work (free pc) and he wants me to upgrade anything that can be upgraded.  Considering he works with 3D imaging apps like CAD, the AMD 7570 needs to be drop kicked.  He wants to game on it when not working (the desktop is for him to work at home - he has another at work).  I figured a 79xx series would be a great upgrade but the current PSU is horribly inadequate for any future upgrade - EVER.  275 watts hardly suffices with any card above the 75xx series.  

Having bought Dells in the past, the PSU can be a pain to upgrade because of size constraints and proprietary limitations.  Does anyone know what options I have in upgrading the PSU to say a Corsair 650TX?  The specs of his machine are:

OptiPlex 7010 MT                                   OptiPlex 7010 Minitower w/ Standard Power Supply
