PC Won't Boot up with new graphics card.

[jtylr270]

Hello and thank you in advance for helpful information you might have for my situation.

I purchased a new graphics card for my Dell pc. I was currently running an AMD Radeon 7770.
The new card I purchased was a Gigabyte Radeon R9 280X. Model # GV-R928XOC-3GD.
After installation of the new card, my pc will not boot up. I am only getting a black screen after powering on the pc. I cannot even switch to my onboard graphics while the card is installed in the slot. If i remove the card from the slot, the integrated graphics port works. Reinserting the old 7770 worked fine as well.

All fans work including cpu and gpu fans upon power up. The hard drive also spins from what I can tell, however no peripherals such mouse or keyboard work while the new 280X is installed.
I called Gigabyte for support and they told me my PCI E slot may not be compatible. I do not know how to check this.
I am using an EVGA 600B Power Supply.

If a 7770 fits in it, so should a 280X. Obviously, the card isn't displaying picture. I would suggest to send the card back, and have them send a replacement.

Do you have both power connectors plugged in to the card. There should be a 6 pin and an 8 pin power port on the card. You must have both to give the card enough power.

I do. Do you think I should try a return? I just wanted that to be last resort.

if your sure that all is placed and connected well.. then its best to just send the gpu back to your seller and have it replaced. as far as i can tell, no conflicts should arise from your gpu.

two possibilities (both equally likely)
1) Dead card ( manufacturing defect)
2) your power supply cannot handle the upgrade
