I replaced my 280W PSU with a 430w TR2.
The graphics card I bought to replace my old one is the AMD Radeon R7 250 OC edition. 2GB DDR3.
When I turned on my computer the monitor displayed no signal and the screen stayed black.
I figured I must have installed it wrong and damaged my computer so I put in the old graphics card and it worked perfectly fine. The problem seems to happen when I install the new graphics card. I made sure the card was inserted properly. Maybe my power supply is not enough? On the box of the new graphics card it needs 400+W. Mine is 430.
