New 380X, No Video Output From Onboard or GPU When Installed

My old AMD Radeon 6870 finally kicked the bucket after years of service, so I decided to upgrade to a XFX Radeon R9 380X.

I followed all the proper steps before installing the new card;
-Removed any and all AMD/ATI software
-Removed all drivers (including registry edits)
-Scanned for leftover drivers, none detected
-Did the "guitar solo fingers" before installing the new GPU

I install the new card, I go to boot up my computer and...

...No display. Fans running, computer idling, just like normal, just no display.

I troubleshoot and try the following:
-Plug in the video cable to the onboard
-"Pre" install drivers
-Check BIOS settings for PCI Express options (no such options available)
-Uninstall the new card, disable the onboard, and reinstall the card
-Check BIOS settings for a onboard disable (no such option available)

Absolutely no response from the above.

Two things to note: The onboard graphics work just fine (I'm typing this with onboard graphics). I do have a 460W PSU, and the new 380x requires a minimum of 500W, but the old 6870 requires the same minimum and I've been running it for years.

Is it a dead GPU? Is the upgrade really affected by the lower watt PSU? Please help!

  1. Your symptoms are consistent with insufficient power. What is the "460W" PSU? I believe Coolermaster has one in that range, that like most of their cheap units, is overrated (I think that one can do 400W-430W).

    It was the stock Dell PSU:

    I've opted to get a 650W EVGA Supernova Gold PSU (figured I should upgrade anyways). After install, I'm finding absolutely no change in my symptoms, just more wattage surging through my non-responsive PC.

    -On board works without GPU installed
    -Video and on board don't function while the GPU is plugged in.

    At this point, I'm forced to seriously consider a dead GPU.

    One thing I did notice this time around, was that when powering off the PC, there was absolutely no delay in the PC itself turning off. This makes me think that it's not even booting.

    I still need help!

    He did upgrade the PSU, and it still isn't working.
    Since the new card never worked, it may have been DOA. Do you have another system you can use to test it? If so, great, if not, contact XFX for RMA service.
