i7 5820k is working with fsp AURUM PT 1000W?

Solution
Yes. It will be fine.

1000w is a lot of power. High end gaming machines don't typically need that much (850w for a pair of GTX 980 GPUs leaves room for overhead). Are you running multiple GPUs, or what type of setup are you after?


of course I have some more ram than usual
 


Those things don't have enough of a power draw to worry about at that level. Build your system using the link below and note the wattage requirement change as you add / remove components. Graphics cards dictate going larger on a power supply...

...and here is a sample build with water cooling, five hard drives, optical drive, and a pair of large GPUs. Note the power requirement in the upper right side of the page. 850w still leaves a lot of overhead.
