QUESTION 1 : ( Anwsered by jyjjy thx again !!! ) So, if i just change my video card ( Radeon 5450 :S.. xD ) for the 5670. Does my PSU will survive and make it work ???? or i need to buy a new PSU ?....

On the official website, they said i need 400w for my 5450, but i dont have that and it work, so im confuse a loooot ( and why HP would make it unable to work ??? )





QUESTION number 2 :

I lovvvve the 6870 radeon hd.....


If i dont have a PCI express 2.1, can i buy a 6870 Radeon HD OR i need a new Mobo ? ...

If i dont need a need Mobo.

Does any Power supply will work on my crappy motherboard ???? if it's 500w and more + it's from a good compagny??? ( corsair, antec, seasonic ( thx to jyjjy ) )


In other way, could i get a 6870 working on my HPE-400f ????? Without buying a new Motherboard !!!




Thx and sorry for all confusion and bad english happy new years xD

I'm fairly certain HP uses standard form factor power supplies in their non-slim/small cases so it should fit fine.

i will put the 100$ for that PSU and get the sexy 6870 :

i get wwwwwwwwwwait to play Total War series on that !!! i just bought the empire-napoleon bundle on steam for 20 the other day
