How to calculate power draw per rail, to see if Power Supply can handle the load?
Your fans and CPU cooler will run from +12. All the others will run from various voltages derived from either 3.3 or 5 volts, and without the detailed specs, you cannot tell the current levels at any voltage. 

However, since your computed max power is 169 watts and the supply is only rated for 160, regardless of how it's divvied up you're probably in trouble. That's not to say it won't work, necessarily, since it's entirely possible that not all the components will require maximum power and at the same time.

But it's probably not a good idea trust this. Murphy's Law applies.
