question about this

I had HP p6230y. I want to change its video card, meanwhile I have to change power supply. Is the size of power supply fit to my HP p6230y?

Thanks,

Newer HP maches use standard ATX power supplies, but there's nothing on the spec sheet to confirm it. Will probably work, but to be safe you should open it up and check the power supply model no. to confirm.
