Bought an old dell optiplex 7010 with a 240 watt power supply and intended to plug in a new GPU, so I got a 550e- solid gear and connected all the cables to get no display, but fans did turn on, specifically plugged in the sata, CPU, and motherboard cables bcs there's no GPU right now, however when I reinstalled the old 240 watt power supply it booted to life and displayed just fine.
