More about will computer compatible power supply have
  1. What is your budget, your usage and time frame for buying? With your current components, assuming you dont have a video card you would need a 300-350 watt power supply. But that doesnt mean much without more info on your needs etc.
  2. My budget would be about £450
    My usage would be about 5hours every day
    I do not know what a time frame is
    I would just want it to play games like minecraft and world of warcraft
  3. Your choices seem compatible, but...

    Will you do a lot of multitasking, or run VMs? The 4 core AMD processor you have is better for such tasks, while a 2 core i3 2120 will be better for games. It will also consume less power.

    You can double check your power requirements using this link:


    But I feel that a 350 watt power supply should be more than enough. Make sure you get a 80plus certified one.
  4. Ok thanks for your help
  5. You should use benchmarks to check for power supply recommendations, not PSU Calcs.
