Mining is rough on GPUs and PSUs.

Not with the immediate intent that you need to purchase a PSU.

Use two or three of the listed calculators to determine the power requirements of your build.

Be sure to include all components.

If a component provides a wattage range then use the high end wattage value.

Also do your own manual tally and add 25% more wattage.

Objective is to establish some consensus on the wattage required to support your mining build.

And do keep in mind that a low end (price, quality, wattage) PSU could do more harm than good.
