More about what system
  1. What motherboard do you have?
  2. you can put in a 7850 and it will be much much better than the 5450.

    If you are tight on a budget the 7770 is also good for its price. Both should run with your system.

    But, the 7850 and 7770 require a higher PSU wattage

    I hear some people put power hungry GPUs in the PCs and they work fine with a Low Wattage PSU, they say the clock runs slower to accomidate the lower power supply. Is this true? what are your specs?
  6. the 7850 will run no problem on a earthwatt 380D. People have ran much more power hungry cards than that on there.

    Some graphics cards will do that to an extent. Not having enough power can cause a gpu to not run properly or not run at all. If you are looking into getting a powerful gpu like the 7850 or 7770 then it will be in your best interest to get a better psu to go along with it.

    not true. the moment the GPU gets overloaded it will do one of 2 things. if it is a good quality CPU thern it will just cut power to the PC to avoid damage. if it is a low quality or bad PSU then the PSU will pop and fry it and may fry any other components with it like the mobo

    So do u consider my PSU good or bad? It has great reviews on newegg and thats why I bought it.
  10. your psu is good and can handle a 7850 no problem.
  11. Best answer
    Definitely get a new PSU if you spend $150 or more on a new graphics card. There are several good ones on sale at NCIX at all times usually for as little as $60 for 650Watts.

    PSU FAN:
    Most PSU's start to ramp up the fan once the load hits 50% power draw. A 75% load may work fine but the noise level will be higher.

    Which card?
    That's going to come down to BUDGET. Your CPU will start to bottleneck at some point but that also varies by game. Some games won't be CPU bottlenecked too badly even with a GTX670 and others may be quite bottlenecked.

    Summary:
    - Decide on a budget for the Graphics card AND a new PSU.
    - Look at the BENCHMARKS for cards in your budget.
    - Look for a 550W to 750W PSU depending on graphics card

    *note sure on your budget but there might be some new NVidia 6xx cards coming in the next few months that cost between $200 and $300 like a GTX660Ti.

  12. 7850 runs with 250W power total system power consumption. Will run no problem on a good 380W psu like the earthwatt

  14. thanks. I was really looking at the 7770. PassMark software ranks it 54th and scored a 2053 on the G3D rating. It fits within my PSUs capabilities and is a huge improvement over the HD 5450 which scored a 311 and ranked over 400 spots lower. Best part is, its only 125 USD which means it won't break the bank and it will tide me over until I build a gaming rig in the next year or so.

    You know what? that card is even better, it will run and its only 100 USD more. My Proccessor isn't too old and the CPU itself is only 2yo. This should be the card I go with. Thanks a ton.
  16. yes the 7770 would be pretty much perfect for your system without the need of spending a lot of money.
  17. Yeah, the 7850 will run on your PSU. It's worth it over a 7770 if you can afford it.
