Best GPU with my PC ( 250w )

Looking to upgrade my GPU, but don't really want to go through the hassle of upgrading the power supply as well.

N-Alvorix-rs880-uATX

AMD Athlon II X4 630 2.80 ghz quad core

4.00 GB

64 bit

250w power supply

Currently rocking the ATI hd 4200 integrated.

So whats the best GPU I can safely run on this system? And also what kind of performance could I expect using it in conjunction with your suggested card?

  1. You should wait for more professional feedback but as far as I know the Radeon HD 7750 is a great card that does not require a powerful power supply.
  2. I agree. HD7750!
  3. The HD7750 requires a 400w power supply: http://www.amd.com/us/products/desktop/graphics/7000/7750/Pages/radeon-7750.aspx#3 .

    250w is a pretty low output psu, you'll likely need to get a higher output PSU to get something noticeably better than you integrated graphics.
  4. The Radeon site recommends 400w or greater for the HD 7750, and other sites recommend 450w.

    Could 250w PSU really run it safely?
  5. try this site for that matter

    Assuming your psu is a good one that delivers the right wattage and all that stuffs.
  6. @OP, Could you post the amps for your PSU? Some 250w PSUs have pretty good amps.
  7. Every specifications I've read via google on it simply state 250w power supply. Doesn't name the type of PSU, or it's amps.

    It's the HP Pavilion p6654y FWIW.
  8. I have a computer running a radeon hd 7750 with a 300w power supply. I haven't had any problems at all.

    I couldn't find anything online either. Is there a sticker of some sort on the actual unit?
  10. Ok I finally looked at the PSU

    it's the Bestec ATX-250-12z

    here's what I found about ampage

    DC Outputs (Amps Max/Min): +3.3V (18/0.3A), +5V (25/0.5A), +12V (14/0.0A), -12V (0.8/0.0A), +5VSB (2.0/0.0A)
  11. You might just be able to pass with any card which does not require an extra power connector but I would go for a card with a TDP of <60w to be safe.
  12. You're speaking alien to me right now, no idea what that means lol.
  13. Best answer
    Well get either a hd 7750, hd 6670, or lower. They require only around 60 W at full load.
  14. Cool, thanks :)
