Here is my current setup:

Phenom II X4 B45 @ 3.4Ghz 2MB L2 Cache
Gigabyte GA-MA785GM-US2H
6GB DDR2 @ 440MHz
HD 4850 @ 675/1045MHz
Seagate Barracuda 7200RPM 500GB
External Hitatchi Easydrive 500GB &
Seagate 1TB
Rosewill RV2-600 600 Watt PSU
Antec TwoHundred(v2)

Looking at swapping the HD 4850 for a HD 4870x2. Question is, name brand aside, would my PSU be able to run my setup with the HD 4870x2? Thanks for your help!
 
Solution
It's possible but only with a real good PSU. Don'know about Rosewill. And 650-750 to be safe would be better indeed.
Measured power consumption two 6870 cards

System in IDLE = 184W
System Wattage with GPU in FULL Stress = 421W
Difference (GPU load) = 237W
Add average IDLE wattage x2 ~ 19W (ATI specified)
Subjective obtained GPU power consumption = ~ 275 Watts
