The problem with OEM systems is they tend to be build for the "model needs" and some room to grow on. Once, you exceed or really start to stuff the system you stress the p/s unit. Any power supply is suppose to be stable within 75% of it rating, the actual 100% can be reached and be stable BUT only for short periods. If the 77-100% is constantly being reached, sooner or later depending on the p/s make-up it will start to breakdown or outright fail. I've always recommend for a "generic" system at least 400W or better. Plus, be of a decent manufacturer. Cheap is cheap and will tell soon enough. Also, its now common to have 500W+ rated p/s units out there, just beware of quality. Check these websites for some info/details:

i purchased this machine, put in an asus geforce 6600, upgraded the ram to 1.5 GB, and the computer is very fast..
my question is, i am not really into "gaming", i am just a casual gamer now and then. i have Black and White, and the game runs great, and i will purchase the sequal. is the power supply that comes with the machine OK for this game, and maybe some others that are not graphic intensive? like i said, i am a casual gamer, and not into any of the newest games.
