I'm looking for input as to the best power supply recommendations. I have a Pentium 4 computer with a Intel 915GAV motherboard, one harddrive, 2 dvd drives and an ATI X700 video card. I built it as a media center PC so I am looking for the quietest power supply out there. Would like something powerful enought and cooling enough for light gaming and some DVD creation type work. I'm thinking a 400W PS would work here but let me know if there are different thoughts out there.Looking to spend around $100, but let me know if there are better ones out there at a different price.
