OK, so this is my first post so take it easy on me. I am wondering what I would need for a power supply in order to safely run two (2) Radeon HD 6950's in Crossfire. Here is my current PC (already built):
CPU : Amd phenom x4 955 black edition overclocked to 3.8ghz (stable)
RAM : G.Sklll Ripjaw 8GB Ram (ddr 1333)
Motherboard : GIGABYTE GA-970A-D3 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard
Power Supply : CORSAIR Enthusiast Series TX750 V2 750W ATX12V v2.31/ EPS12V v2.92 80 PLUS BRONZE Certified (62 Amps on 12v rail)
Graphics Card : SAPPHIRE FleX 100312FLEX Radeon HD 6950 2GB 256-bit GDDR5 PCI Express 2.1 x16
SSD: Crucial RealSSD C300 CTFDDAC128MAG-1G1 2.5" 128GB SATA III MLC Internal Solid State Drive (SSD)
Hard drive : Western Digital Caviar Blue WD5000AAKX 500GB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive
DVD Drive : ASUS DRW-24B1ST/BLK/B/AS Black SATA 24X DVD Burner x 2
TV Tuner : Hauppauge WinTV-HVR-2250 Media Center Kit Dual TV Tuner 1213 PCI-Express x1 Interface
Now, I am wondering if 750 Watts with a 62 amp 12V rail is enough? Or am I going to be treading dangerous waters? I have been doing a lot of reading and researching and the info seems to be all over the place! Some say 750 Watts (even AMD's own site) with 50 amps is enough but some say 1200 Watts with 80 amps is required. I also used the Extreme Power Supply calculator and it says 750 Watts with 62 Amps is plenty, hence my confusion.
What is everyone's thoughts?
Thank you
