Your build list looks very nice!
That power supply should be sufficient; if anything, you could probably get by with a smaller one.
Regarding the power actually used by your PC, your systems demand will depend on how hard the CPU is working, etc., NOT the watt rating of the power supply.
Your system will be running probably be running under load somewhere between 300 and 550 watts (rough estimate), so the power supply will be running at less than 100% capacity - and that is a good thing!
Get the Pro version, set system load to 100% and capacitor aging to 30%. Add 10 - 15% to the calculated wattage to be safe. Pay attention to the amperage on each rail.

Hi Harm and Jim,
Thanks for responses.
What does " Pay attention to the amperage on each rail mean?" what is a rail?
A rail means the amperage on the 3.3 V output, the 5V output and the 12V output. In some cases the overall wattage seems sufficient, but the output on the 3.3V rail may be less than the PSU can supply, or it may be troublesome with the 5V rail. It depends on your components whether that is a problem or not, but I once (two years ago) had selected a 1000 W Zalman PSU, but discovered that the 3.3V rail did not deliver sufficient juice to power all my hard disks so I needed another PSU. Hence my warning.
Unfortunately Im not that tech savy so dont really understand the details in your response.
Not that Im questioning but would you be able to corroborate what Jim says above that 1000w coolermaster seems fine and I might even be able to go slightly lower. (i dont think i wil though).
If possible I would just like second corroboration without having to work through the calculator (Sorry I seem a little out of my league with it) ?
Another thing... If you want to have a quiet PC, I read somewhere that if you oversize your power supply and it has a thermostatically controlled fan, you can run in a range most or all of the time without the power supply needing to speed up (and get noisy) in order to cool itself off.
I know with my P/S, a Corsair AX1200, it could be considered oversized for my system needs but I simply love how quiet it is ALL of the time.
