  1. It will cope, but i would seriously consider investing in the near future in a 600-700w PSU from a good qaulity brand like, corsair, antec, seasonic, enermax - etc etc.
  2. Any good 500 watt PSU will do.

    One of my systems has an OC'd Q9550, 4 GB RAM, a GTX260 - a card with similar power requirements to the 4870, a Gigabyte EP45-UD3P motherboard, 3 hard drives and an optical, and a Soundblaster card all powered by a Corsair 750TX.

    Running 3 instances of Prime95 to load the CPU and 3DMark06 to load the GPU and the fourth CPU core, it pulls 375 watts from the wall as measured by my Kill-a-Watt meter. Figuring 80% efficiency, the system pulls 300 watts from the PSU.

    it will do the job but its not a great PSU. a solid 500w like dadiggle recommended (it can provide 500w continuously unlike the thermaltake) is a better choice. the antec EW 500 was on sale on newegg, another solid 500w unit. the people who state you need a 600-700w unit have no clue what they are talking about.
