A Guide For New PSU Shoppers

See What KitGuru Is Shopping For

While PSUs could arguably be the most boring component to shop for when speccing out a new build but it is one of the most important.  As many have discovered, trying to run high quality components with a PSU that delivers questionably stable power leads to any number of intermittent issues.  It’s not just a question of enough wattage, you need a PSU that has solid rails that do not droop below ATX specifications.

To help those trying to find a decent PSU, this guide from KitGuru is a good place to start.  They discuss the different types of cabling and some rough guides on just how high the wattage on your PSU needs to be.  They also describe what the maximum ripple from the PSU should be for each of the wattages your PSU provides and the slightly tighter range that they look for.

They conclude with several different PSU recommendations at a variety of total wattages, if you just want to skip to the end.
