Hello Soldier,

With this card, you need to make sure the mobo can hold it, as well as having the extra power cable for it.

I think Dell does this, I don't know about HP: They have their mobo's specially made with power connections that only work with their PSUs. So make sure you are VERY careful there, because if you are wrong, you WILL destroy the mobo and possibly the PSU. Other than that, installing a video card and PSU is very simple. Just unplug and unscrew the old PSU, and put in the new one in reverse of that order. Video card, pull out old one, push in new one. Done. Make sure it is seated properly.

If you need more specific or simplier info, let us know, we will be happy to help.
