Can I upgrade Graphic card in HP Pavilion p6240f

It doesn't give any data on the PSU but nothing in the system is barring you from adding that or any other card.

Come back after you get it and give us the details on the PSU and we'll be able to tell you what GPU's it could handle or if you'll need to replace the GPU as well (just as a note, almost all PSU's that come from HP suck and you'll want to replace it).
 



Ok thank you for your help..what is a good PSU to replace it with..Not so good building a PC trying to find one i can modify to my liking. All i do on the pc is Play Aion and watch tv..lol
 
Corsair, Seasonic, PC Power & Cooling are very high quality brands.

For an HD 4850 you'll want about 450 watts and 30 amps on the 12v rails. Don't worry about the numbers just yet, we'll help you again when you come back after getting the system.
 


thanks for the help...Do you know which is a good Power supply and card that work with the hp..Since you have done it before?
 


Trying not to switch out the Power supply..well that card work off a 300watt PSU? That is a guess what HP has in the computer..If so i would like to have a HD477o in it:)
 
You base that on what?

Like I said, you need to check, both DELL and HP put in far better quality PSUs than their ratings suggest.

Research it, and you'll see most AMP and efficiency ratings on them merit far higher classification on other 'name' brands.

And you still haven't explained how that 2.4W less draw of the HD4670 you recommend is going to be that big a difference.
 
Other sites have a computer with the 4770 drawing about the same power as one with the 4830, approx 226 to 245watts.

The chart showing it drawing less power than a 4670 probably doesn't have it running at 100% GPU load.

But yeh, the wattage difference between them isn't huge, maybe around 20-30 depending on which chart you're looking at.
 
While they didn't use FURmark as has become a more common practice recently, they did run the card at idle, 2D load, and with a heavy 3Dmark06 load with 4XAA @ 16x10 resolution, and the HD4830 in that same test ran 35W more.

I trust their tests more than those that test and entire system and where the same setup fluctuates from review to review greatly showing the draw of an entire system (mobo, CPU, memory, HDD, DVD, LEDs) along with the graphics card.

Even the subtle differences in the same chip mobo can make a system power draw change 20+W, so total system consumption AT THE WALL SOCKET is not a good indication of power use or power supply need for one part.

Even their most recent test, running the GPU @ 100% load using yields only a 2 watt difference between the two.
 
Delta makes quality power supplies, in fact the recent Antec Earthwatts series are manufactured by Delta (they used to be made by Seasonic) One option is the 4770 that the Apeman mentioned, another might be the 5750 which uses about 68watts of power, but i've never installed one in a HP and the dual socket rear bracket may be a problem. I can't say for sure if it would work.
