  1. What is your 250 Watt PSU's +12 Volt continuous current rating?

    It should be specified right on the power supply's label. You can also post the make and model of the power supply unit.

    Its LiteON model no. PS-5251-08
    input 100-127V ~/6A 50/60 Hz
    200-240V ~/3A 50/60 HZ
    out put +5v-/25A max +12v- /14A MAX
    +3.3v - /18A MAx -12V -/0.8A MAX
    Combined power on 5v and 3.3v rails not exceed 165W MAX
    combined power on 12v and 5v Rails not exceed 218W MAx
    Continuous total DC output should not exceed 250W MAX
  3. That thing draws just 55W, so yes, regardless of the PSU specs.

    Yes. There is enough capacity on the +12V rail to handle the CPU, GPU, motherboard and HDD.

    FYI the DDR3 version of the Radeon HD 6570 has a Maximum Board Power of 44 Watts.

    Are you using the card in a slimline case or standard mini-tower?
  5. should be no problem
  6. I tend to agree.

    The 14Amps provided by the +12V rail is distributed between the CPU and the graphics card.

    The TDP of your CPU is 65W but it likely consumes significantly less since this is a maximum value for the entire group to ensure proper thermal management. Still, I'll use it.

    Assuming 55W for the card and 65W for the CPU we get 110W. I'll round that to 120W for easy division and we get a requirement for 10Amps.

    From the equation:
    Power (watts) = Voltage (Volts) x Current (Amps)

    You need 10A. You have 14A.

    No issues likely with the rest of the system.

    *It seems likely that you'll go over 50% use of your power supply so your PSU fan will increase. You can actually find deals at NCIX for good 450W PSU's that would be much quieter and are more reliable. Whatever.


    Diablo 3:
    You should be able to get playable frame rates out of your system with the HD6570. I was going to recommend you get RadeonPro to enable Always ON Double VSYNC (usually forces 30FPS) but apparently if you have VSYNC enabled in the game AND your computer can't get 60FPS (you won't) VSYNC automatically synchs to 30FPS.

    VSYNC is to avoid screen tearing.

    I'm still confused over NVidia's persistent statement about how VSYNC works. How is it then that FRAPS will show games vary between say 35 and 55 if it's supposed to be synched at 30FPS (VSYNC ON)? Makes no sense to me.

    So you may wish to try the RadeonPro method. When I tested it in another game it simply showed me a solid 60FPS with normal VSYNC and 30FPS (Always ON Double VSYNC).
