Doing a re-fresh and replacing 3 285GTX's (205 Watt) with 3 GTX 780 TI's (250 Watt) and I'm concerned my PSU won't be up to the extra load. Running a Silverstone OP1000W (80 Amp 12v rail).
From my personal estimate, power draw from CPU and GPU are at best 75ish amps and at worst 80+, not including the case fans and D5 pump. Used this tool to calculate power requirements: http://outervision.com/power-supply-calculator and came up with 1187 W requirement at stock speeds and 1529 W requirement overclocking CPU/GPU's Whats a reasonably good PSU (not the best/most expensive) that can run the below setup without being pressed too hard?
-Asus P6X58-E Pro or Asus Rampage II Extreme (not sure yet)
-Intel i7 965 - 130w, 11 amp - Plan to run at 4GHZ @ 1.4V (where it runs stable currently)
-x3 GTX 780 TI - 250w, 20 amp (x3) - Plan to run at 1200ish core (107% power - ~270w and 22.5 amps each)
-x4 HD's (x2 10k and x2 7k rpm)
-x1 SSD
-D5 water pump (cooling CPU and all 3 GPU's)
-30w / channel 6 channel fan controller x 5 120's (360 and 240 rad) - 15 amp max
-x2 200mm fans
-x1 140mm fan
-x1 DVD
Thanks!
