ADD2PSU Adapter 24PIN Molex Multiple PSU Power supply connector Relay Adapter

Works exactly as designed; offers a quick relay to turn on a second PSU when the PSI -to-MB connector is already connected to PSU 1. This relay tells the second PSU that power is applied (from PSU 1) and to power on, great little design!

Added this to my mining rig and it controls the second psu without an issue. Good product
