Our Verdict
The Raspberry Pi 4 Official PSU is without a doubt our top pick among Raspberry Pi 4 power supplies. Nothing beats a power supply made by the people behind the Pi itself and designed specifically for the Raspberry Pi 4: the perfect voltage, top build quality, and a cohesive overall look in both black and white color schemes. The lack of a switch may put some off, but a third-party one can be obtained relatively cheaply.
Another top option is the CanaKit Raspberry Pi 4 Power Supply. Among third-party purveyors of Pi parts and accessories, CanaKit rubs shoulders with the most reputable. Simple, reliable, and practical, it’s a clever way to avoid the slight premium stamped on the official Raspberry Pi option and still end up with a quality power supply. Once again, no switch with this one, but CanaKit has you covered with our following recommendation.
The CanaKit Raspberry Pi 4 Power Supply with PiSwitch is exactly the same as the one just above but packaged alongside CanaKit’s excellent PiSwitch, which is made specifically to work with the Raspberry Pi 4 and deliver a simple way to power the Pi on and off without unplugging any cabling. If a switch is a priority, you can’t go wrong with this pick.
Finally, you can save a bit of money and opt for the Geek Pi Raspberry Pi 4 Power Supply with On/Off Switch. This comes with a slight downgrade to build quality and looks, but when it comes to powering the Pi, the Geek Pi Raspberry Pi 4 Power Supply with On/Off Switch is just as reliable as the power supplies above. It also includes a built-in switch as an added benefit.
With that, we’ll call an end to our guide to the best Raspberry Pi power supplies out there. Have any pressing questions, concerns, comments, or suggestions? Feel free to get in touch via the comments section just below.
