are these WATT calculations for a Skylake build correct?

I'm doing the wattage count using Outer Vision's calculator.

Here is my system:

MOBO: Asus H170 Pro
CPU: Intel i7-6700
RAM: 2x8GB DDR4 2666Mhz (total 16GB)
VGA: AMD Radeon R9 380 4GB
SOUND: Audigy 2
HDD: WD Black 1TB SATA III 7200RPM
SSD: not yet, but pretty soon
OPTICAL DRIVES: Blu-Ray recorder, DVD recorder
FANS (3 in total): custom cooler on the CPU (Arctic Freezer i11), one fan in front of the HDD, one fan at the back of the box pushing the air from the CPU cooler outside
USB DEVICES: two 2.5" external HDDs of 2TB each that power from USB only, my mouse, my keyboard is PS/2 but in the future I might get a USB one

I've set the calculator to be at 100% load (that option is only available for CPU, no GPU) and operate at 24/7. From what I see in the calculator, the 24/7 option really puts a strain on the PSU, which is why you need a beefier PSU for that.

And the results are in:

Load Wattage: 447 W
Recommended UPS rating: 850 VA
Recommended PSU Wattage: 497 W

So a 500W PSU for me?

EDIT:

I think I made a mistake in my logic.

My total load is not 450w. First, that calculator adds some watts because I tell it to go for 24/7 operation. Second I don't plan to use both of my external USB drives and optical drives when playing a game (that utilizes GPU in full).

Removing the USB drives, the optical drives, and the 24/7 option, my power consumption goes to 370w.

Awaiting comments on this.
