What kind of power supply do I need?

[AstroMagic]

I am running a hp pavilion p7-1125 computer. i added 4 more gb of ram to it that doesn't work but i will soon get a 1333hz ram that works with my computer. So what kind of power supply do i need if i want to upgrade to a sapphire radeon r7 240?

A R7-240 is only marginally stronger for gaming than the stock Intel integrated graphics.
And... you have only a 300w psu; A R7-240 wants a 350w psu:

I might suggest a stronger more efficient $70 GT730(64 bit) or a stronger $130 GTX750. Both of which will run on 300w.

So i dont need a power supply? I actually might consider the GT730 or the 750 thanks! Also what games can they run at what frame rate can do they at what settings?

Certainly much better than what you have.

Best to run and see. Or, look for benchmarks of the games you are interested in and go from there.
