hey all so im looking at upgrading my current rig and i want to make sure i have the power.
currently i have a 1000W power supply and once i buy all the things i wanted ill be running
2 GTX 480 (power hungry monsters)
an I7 2600k
120mm fan x6
potentially 2 arctic cooling accel x3 for the 480s
Blu ray drive
and 1 500gb HD
Thats system power draw, its a bit odd for any GPU to draw 450W by itself although both cards together will draw like 400W-600W, the CPU is 95W, a little more if overclocked, all the fans will draw less than 10W each at full speed, a hard drive will draw 12W, more for higher RPM rated drives, card readers will draw hardly anything, the same goes to the blue-ray drive.
I would say a 900W or 1000W would do, better to have more power than less available.
It would draw a total of around 800W i think but i can't be certain.
