Low profile graphic card and power supply?

Hmm... Given the rating, I have the impression that the power supply that came with that system was designed to be just BARELY sufficient to run what it had. In other words, any component upgrade would entail upgrading the power supply.

However, I'm not precisely certain what form of power supply unit (PSU) the SlimLine uses. I know it's not a standard ATX-sized one, since that won't fit into your case. So to be honest, I'm not even positive if there *IS* one you can buy to upgrade, though that's unlikely, in my opinion; someone else will have to chime in on that.

As far as installing it goes, it's actually rather simple and straightforward, so far as you remember all the places that needed plugging in. (probably just your motherboard, DVD drive, and hard drive) The plugs are all designed so that they cannot be inserted in the wrong way. Typically, all you need is a medium-sized Philips-head screwdriver to take care of the screws holding together the case and holding the PSU in the case. The rest is just dealing with plugs and sliding out the old unit and sliding in the new.

*** up...why don't you leave the nerd cave and go deal with the world...try calling the world a dumbass...let me know how it goes
