Hi. I am going to mine ether. The PSU is 450 watts. I want to run 2+ RX 480's on it. Note: The PSU will ONLY be supplying the gpu's and 2-4 pcie risers. Thanks a lot!

At full load? A single card will use about 220watts under full load. So you can only safely support one, if you want to push your power supply to the ragged edge you can try two though I would not recommend it especially if its some junk generic psu, all that will do is create a fire hazard.
