Eh, yeah the HP power supplys are junk. Forgot about that one. I had replaced the PS in my wifes a year previous, so it wasnt an issue when it came to the motherboard swap. Still, if his PS isnt hurting now, I dont see any reason why it should with the new MOBO, if he's not upgrading any other components. And while I tend to agree with the onboard sound/video, disabling performs the same function, and its damn near impossible to find a modern motherboard without onboard sound. Video yes, but not sound. They all include it for some reason.
