[Solved] 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).

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?

Thank you for the info...
may i ask is a SAPPHIRE Radeon HD 4670 1GB compare to XFX GeForce 9500 GT 1GB?

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

I know what it recommends but that's over estimation, whereas PSUs on DELL and HPs are under-estimations, best to check the Amps on the rails.

Did you notice it also draws about the same wattage as the HD4670?

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.

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.

I still think this is one of the best articles written about how much power our systems actually use and the breakdown of what uses power and when. The author made the hardware to test each component in the system, it's worth a full read.
