Installing a new 5670 on my computer?

[driftkingz109]

Hello, my current computer now is the P6655D, and the link to its information is right here. http://www.villman.com/Product-Detail/HP_Pavilion_p6655d_DT_PC anyway, the computer comes with the standard motherboard "Iona-GL8E". it also has an HD 5450 1gb card, and it comes with a 250 power supply. I wanna upgrade my Power Supply and my Video card but my mobo only has ONE x16 graphics slot lane. i was wondering if the HD 5670 is compatible? and if i can put a new power supply into the computer aswell? i dont wanna risk getting a blank screen when i turn on my computer with a new 5670. So any help is appreciated

You should be fine to change the psu and graphics card in your pc , you should not have any problems with it not being compatible.
