is a 800 watt brozne cerfied psu enough for a gtx 660 non ti sli with fx 8320 @ 4.00ghz and 9800 gtx+ physx card ? i do have a h80i a few fans 1866mhz 16gb ram installed as well,i want know because a phsyx card will take the strain off the 660s for some games but i dont want to kill my psu in the long run the only reason I am running 660 sli is because i got the second cheap and willing to wait for the 770 to drop or just til black friday

yes. you need a minimum of 450w for a single 660 so 800 will run 2 of them no problem along with the 98gt. although the 98gt may well hold the 660's back... i would suggest you try the system with something like archam city with physx enabled and remove the 9800gt to see if you get or loose performance.

ok thanks, would oc the 9800 give me better performance because my board only has 2 pcie 16x slots 2 4x
 
wouldnt make any difference. if its holding the other cards back an oc would only slightly change that. not enough to free them up i would think.
like i said you will likely get better physx performance without it attached at all. 2 660's is a pretty powerful combo.
