I'm trying to build a rig too, but i think it's not convenient with only 1 card. You need at least a motherboard, a crappy cpu and hd, 2gb RAM, and a good psu. But 450w should work for only 1 card..

The 290x requires 750w if I'm not mistaken?

(never ever turn off a monitor with catalyst, unless you have a couple of hours to lose to put it back on) edit: forgotten how to do this |

450w and 290x is not a good combination to run.

Depends on your 12v rail(s). Feed the 290X anything less than 25-30v and you'll get nothing.

R9280x consumes 350W so 290 needs more to work and hash properly.

If its not working try headless in Linux.
Maybe the card is damaged.

sorry, just not true, I have one...  people should start to look at the spec. rather than making assumption |

R9 280X can draw power from PCI-E (about 75W) and from 6pin + 8pin (175W) or 8pin +8pin (200W), so max consumption is somewhere around 250W. You can see consumption when mining:  |

Was the days were doge had met moon! Epic days!! may-be, I don't know, but what you said for the 290x is just wrong. It is a more powerful card than the 280x but the power consumption is smaller... (and 350W is probably the power drawn by the rig and not the card itself...) |

If the card is not getting enough power then the fans will be 100%
Put your ear to the fans and listen.
As soon as you start your computer fans will go to 100%, means low power or no power.

To Hash or not to Hash, that's what the question

I have ASUS R9 290X taking 350-390W @ WALL with mobo/ram/cpu/hdd
R9 295X2 taking about 670-790W @ WALL with mobo/ram/cpu/hdd
Most likely your power supply does not provide enough power on 12 rails.

Actually the 450watts is enough, but you can only run stock clock.
