I've got a 600W and 2X Geforce GTX 460.  The 600W supply is not sufficient to power both video cards.  Its also loud and hot as all get-out.  Not going to happen with a low TDP.


thats why I said old sli cards ... newer nvidia cards dont use that much power and amd even less ... like i said gtx 680 and i7 2600k only 300w

edit:

300w is the max you need for a current gen pc if you use a single core gpu ... (of course you need higher power supply then 300w)
