BlueRigger HDMI to DVI Cable 6FT vs Raspberry Pi 15W USB-C Power Supply US - Black — Head-to-Head (2026)

Our verdict

Neither wins. The BlueRigger HDMI-to-DVI cable and the official Raspberry Pi 15W USB-C supply do completely different jobs in the same build: one carries 1080p digital video to a DVI-D monitor, the other delivers the 5.1V/3A that keeps a Pi 4 from browning out. If your monitor already has HDMI, skip the cable. If you're powering a Pi 4 from anything other than a proper 15.3W supply, the PSU is the non-negotiable purchase.

Buy the BlueRigger HDMI to DVI Cable 6FT if your only spare display is a DVI-D (24+1) or DVI-I (24+5) monitor. That's common when you're recycling an older 1080p panel for a Pi 4, Roku, PS4, or Xbox One, and this cable handles the connection on its own instead of an adapter stack. Buy the Raspberry Pi 15W USB-C Power Supply if you're building or fixing a Raspberry Pi 4 Model B at all. The 5.1V/3A brick is the single component that determines whether the board runs stably under load, and no phone charger reliably substitutes for it.
