I bought a new graphics card gigabyte radeon hd 6570 2gb ddr3. I had 275w power supply back then. After installing the graphics card pc turned on then off.
I asked someone and he said you need 450 w power supply. I then bought a 450w power supply. The power supply ran on previous graphic card (ati x600 series) but giving same problem with new graphics card. Specs:
Optiplex Gx620 Dell motherboard
4gb ddr2 ram
Intel Pentium D 945 3.4ghz
PSU 450w
What could be causing the problem? Is it psu or gpu? Please answer

Do you mean it goes right off after you turned it on? That sounds like a short circuit to me, try to only plug in the motherboard + graphics card and test it again.

When i turned on the switch after installing gpu and psu then pc automatically turned on then half a second turned off and repeated this process automatically without booting anything.
