  2. mines is zebronics 400W... please tel me abt the performance of hd5570

  4. what do you want to do with it?
    It will handle most games at a moderate resolution fine with reduced details. But unless you upgrade your PSU, its not going to get much better than this.
  5. is going for 500w psu sensible?
  6. Going for a quality PSU is sensible, even a 1200W generic wont do you much good for the most part.
  7. ok give me some more options for gpu

    The CX430 has ~350w on the 12V rail, the CPU takes up 100w, everything else 50w max, which leaves you with 150W for the GPU and 50W of wiggle room. The 6870 uses ~130W on load, so yes, a Corsair 400w handles a 6870 fine.

    The 5450 asks for a 400W, does it really need it? No. But since over half of the "400W" on the market outputs ~150w stably, then yes.
