The stock ps for this system m260n, is less than 200W. I need more power. Problem is the physical size of the unit. There is only space for a PS to stick into the case 4"! There is no room to move the optical drives, as there are no more bays. Any suggestions? Sure would like to get something in the 300W+ range, at least. Similar queries on other boards resulted in a lot of views but no responses. I have a lot of trouble getting thru HP's web site. Last time I did get to the right area, they only referenced an exact replacement for the stock PS in their hardware area. 'Preciate any assist........ Since I can never find an appropriately sized ps, maybe I could just get a standard sized one and leave it hanging part-way out rear of the case, hmmmm? Just a thought, any suggestions?
