When it comes to building a new PC most of your focus is going to be on things like your video card, your CPU, SSDs, and maybe your case. That is because those are the components that affect the performance of your PC and with your case, it is the most visible component. So I completely understand why your power supply isn't at the top of your list. You do have to remember though that a poor quality power supply can take out all of those other expensive components in an instant. I recently started looking at components for a new build for my main rig to replace the monster Fridge build. For the power supply, I wanted to go with a lower wattage because I had only planned on having two video cards, but I wanted to stick with Corsair and I needed fully modular to change out the cables later. So the Corsair HX850i came to mind. With its Platinum 80 Plus certification and a few cool features. The build it is going in is coming along, so today I?m going to take a look at the HX850i and see what it is all about.
