    I have a Dell Optiplex 7010mt and I gave it a rx470 graphics card and a new power supply it was ran fine for a week now but when I was using it the pc just shut off. So I clicked the power button it turns on steady white light but no signal to my monitor at all. I tried cleaning the ramm making sure everything is plugged in I removed the cmos battery then put it back in. I unplugged the gpu then tried to run it didn’t like it so I put it back. I plugged in a cable to the motherboard for video nothing at all. I NEED HELP!!!!

    The Dell OptiPlex 7010 Mini Tower comes with a 275W power supply.

    The AMD Radeon RX 470 graphic card uses 120W of power.

    What's the brand and model number and wattage of the replacement power supply you put in that Dell?

    Is THIS the power supply your Dell OptiPlex 7010 minitower now has, or is it a different model?

    I'm not a hardware diagnostic expert, so be patient until someone else here who is replies.
