Hi, I'm upgrading from an old 8800gt to a new card in the 100-160 range.
I've narrowed it down to these two: 650 ti and 7850
Now I know the 7850 is a lot better than the 650 ti, but listen. I want to know if the 7850 will run on the thermaltake 430 watt dual rail 12v (35 amps in total)
Also, I see that the 8800gt has a 26 amp/450watt requirement and that it runs fine on my PSU. The 7850 requires only 21 amps, but a 500 watt PSU. Is the 500 wattage really needed? My PSU already runs the 8800gt, which draws more amps than the 7850. If the 7850 will run on my PSU I will get it (I'm not going to OC and I don't want to upgrade my PSU). If it wont but the 650 ti will then i will get the 650 ti ( 20 amp/450 watt requirement). I got the power info from the site below:
