Dear Tyler, I am using an Antec SL450 450W power supply. Model: SL450 with specs at http://www.antec.com/specs/sl450_spe.html I am of limited knowledge but this seems pretty good, tell me what you think. isnt that good enough? I have been using them on 30 systems for over a year. Do you have recommendations perhaps for a UPS or a power conditioner? I have used a good belkin surgemaster, but perhaps environmental surges are getting to my machines.....
