psutierlist.com lists the best power supplies available on Amazon.

Unlike other Power Supply Lists, we only list Power Supplies that are available on Amazon. We were fed up with looking at other power supply tier lists where the power supplies listed (whilst great) were simply not available to purchase. Our Power Supply list provides accurate availability and pricing of the best power supplies available to purchase directly from Amazon.

We are currently going through the process of reviewing every Power Supply on our list, as I’m sure you can imagine, this is a time consuming process, so some of the review links below may not currently be active.
