Graphics card without new PSU?

Hello everyone, I am thinking about buying a graphics card since I am on integrated graphics, but I am on a really tight budget, and I can't really afford to buy a new PSU. This says about my computer in detail: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c03511113&lang=en&cc=us&taskId=101&contentType=SupportFAQ&prodSeriesId=5295969&prodTypeId=12454

But in short, my computer is
A4 5300 CPU (3.4 GHz)
4 GB RAM
500 GB
300 W PSU

Is it possible to get a card which runs most games okay without having to get a new PSU? And if so, what card/s? I do understand that I may have to get a new PSU :p But I thought I would check first, thanks in advance.

    The ones that need 300W won't play current games

    I see, well thanks anyway!
  3. I would recommend the Radeon HD7750. It will run on that power supply with minimal issues. The ratings on that website are based on manufacturer recommendations, which are overrated.

    Are you sure about this? And what counts as minimal issues? If it doesn't cope will it what would happen to my PC?
    I have looked it up and it seems to be an OK card for its price too.
  5. I am positive. I've run the card before on a 300W power supply. Its been running on my cousins computer for more than half a year now with no problems.

    AMD says the recommended is 400W, but that is hilariously overstated. You will be fine.

    OK, thank you very much mate :) Also I managed to find a PSU calculator thing, and that says my PSU will be enough too! I do apologize, but I picked the best solution before you commented, but you did properly solve my problem. Thanks again!
  7. but you have to keep in mind that your cpu might be a bottleneck in some games

    Yeah, I have kept this in mind, and my plan is that once I can afford to, I will buy a new CPU (And possibly a new PSU if needed at the time) Or maybe for Christmas or something. I feel like a dedicated graphics card is more needed now than to upgrade my CPU :3
  9. The 7750 should be a good mix with your APU, and you might even be able to crossfire it.
