Graphics card not recognised (?)

[Gapehorn]

So i just bought a Asus GTX 750 Ti OC edition and installed it into my prebuilt system as an upgrade , the fans are running but theres no display output from the graphics card it self however , when i plug it into the motherboard display output thingy theres a signal . so did i do anything wrong ?

I tried both VGA and  DVI , both dont show anything from the gpu

I did a little bit of research and people seem to be having a similar problem until they disable their onboard graphics in the bios.

but it did have a gpu pre installed tho i just swapped it out with this 750 ti

Plug the monitor to the onboard video port, Boot into the Bios of the computer, and change the primary adapter from Onboard Video to PCI-E, then switch the monitor back to the 750 TI and it should work.

OK so i tested it with another gpu , the other gpu managed to show a output while the 750 ti couldnt , in this case could it be the gpu ? i

okay it is probably a dead gpu

but the fans spin tho

[Codymm03]

still can be dead or not enough power

OH MAYBE ITS THE POWERRRR

CPU : i7-4770

RAM : Generic 8gb kit

GPU : ASUS GTX 750 Ti OC edition

DO you think 300 watts is enough

I did a quick sample  build and it was on the edge
