Also 1500 watts is redundant as present and future parts are much more energy efficient so they need less and less power to run them
Hopefully George from Corsair won't mind if I repost this here....
"
What is needed and what is wanted are two very different things. People have been saying this to us since we started selling PSUs 8 years ago. "Low wattage is the future."
The point is, it's not happening. X99 is going to be using huge amounts of power. NVIDIA announced the Titan Z today. The 780 Ti, the 290X, all new GPU architectures are using huge amounts of power, and the ultra-high end people are putting multiple GPUs in their systems.
The truth is that the average power consumption of a "mainstream" computer will go down. But there'll always be people pushing the limits. That's who this is for."........
Yes, I realize I may never use this much power, but at least it will be there going forward should it be required. I currently am maxing out my old 1000 watt PSU, not a nice feeling when it causes issues.
As much as I am chomping at the bit to build a new system right now, today, I won't. I am in no rush, and I believe in getting what I want, and sometimes " need " has nothing to do with it. I don't " need " tri sli, but I am going to put it in my new system. Same applies to the 1500 watt power supply.
Lets not forget what the P stands for in PC.
