Raspberry PiOfficial 5 V 2.5 A Power Adapter for Raspberry Pi 3 - white

This is a excellent PSU for the Pi. I used a Pi 3B+, and retropie, and this PSU performs perfectly - no crashes or the dreaded undervolt image at the top of the screen.Don't go cheap on a Pi PSU if you use it for retropie, always use the offical PSU.

It's a simple power plug that comes with all sorts of plug adapter. The only downside is that there is no power switch on the cable . The color is definitely white.

These are the best supplies I have used for the Raspberry Pi 3, even some others that are rated at 3A still cause the lightening bolt to appear. With this one the Pi is rock solid and works without a problem..
