We spent 20 hours on research, videography, and editing, to review the top selections for this wiki. No components draw as much electricity from a system as do today's high-end graphics cards. So it's of prime importance that every gamer provides their GPU with a power supply that will enable it to process gigabytes of data per second. We've ranked the strongest and most reliable PSUs for supporting the machinery you need for the ultimate gaming experience. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best gaming psu on Amazon.
