My brother just upgraded his aging custom build. New FX AMD CPU, AM3+ Mobo, RAM, and a nice Samsung Sata 6.0 SSD, and new Mid-Range Radeon GPU. Problem is that upon my advice he did not buy a new Power supply. In his words, "I have had no issues from my PS so I feel no need to spend the money." Although his 5 year old (Ultra brand 500w Modular PS) seems to be working just fine with his new build, I told him that he may be playing on borrowed time with it. If by chance this old Ultra PS of his bites the dust, will that or could that damage his new hardware?
