The power supply unit (PSU) isn’t merely an unexciting black box that sits at the bottom of your computer case - it’s a critically important part of your entire system.
It’s the job of the PSU to convert the power that your computer receives from the mains electricity from Alternating Current (AC) into Direct Current (DC). Not only that, but a PSU also modulates this DC output so that it sits within the fine tolerances required by many of the components in your system.
A good quality PSU will also protect your system in the event of a power surge. Without a good PSU in place, a power surge could potentially overload and fry all those expensive components in your system!
When buying a PSU for your system, look for 80 Plus rated PSUs. These are power supply units that always operate at 80% efficiency at a minimum. 80 Plus rated PSUs have a scale of efficiency, running from 80 Plus and 80 Plus Bronze, scaling up across Gold, Silver and, at the top, Platinum.
The very best 80 Plus Gold and Platinum PSUs will operate at as much as 94% efficiency.
