Ok I have this system. Its pretty much stock (was planning to add another stick of 512MB RAM [Kingston PC3200 if you need to know]) and has a 250w psu, according to HP/Compaq. I'm just curious to know if its possible to add a AGP video card that suggests a "minimum" of 300w w/o having to upgrade the PSU (which will be a bitch since microATX PSUs seem hard to find). If its safer that I do need to upgrade my power supply just suggest one I should look at. Thanks!
