Go to just about any listing for a pre-built gaming pc, and you’ll often see a variation of the same question pop up in the comments: “The specs are nice, but what about the power supply?” More often than not, that too good to be true deal on a pre-built computer is too good to be true because the manufacturer decided to save money on the power supply. Some manufacturers don’t even list the model of the power supply included in the build — either because they know it’s inferior or they suspect the average consumer doesn’t care. But you should care about what power supply is in your PC. In fact, the PSU can be the difference between life and death for your rig. A bad power supply can brick (severely damage) your computer, while a great power supply allows you to get the most out of your components and even explore the wonderful world of overclocking (running your components faster than intended for better performance). The problem is that there’s just not a lot of information out there to help those who want to separate inferior power supplies from superior power supplies. It’s not all about the watts; there are just some power supplies that are better manufactured than others. That’s why we decided to rely on the Pure Power 11 700W CM from be quiet! for our official Den of Geek gaming PC.
