Redundant PSUs are actually TWO PSUs in one case - if one quits, the other takes over. Only needed for computers that must be up 24/7...
. With the PC P&C PSUs you don't need to get the Turbo Cool (noisy) models, they also have the Silencer series which are about a quiet as any.
. The turbo cool is meant for those situations where the PSU fan will be the only exhaust fan for the case - if there are other fans, you could swap out the Turbo Cool PSU fan for something quieter as its only job will be to cool the PSU itself.
. Good for moderate $$$s are Heroichi (HEC distributed by Compucase in US)/Sparkle (Fortron based models - look for FSP in the model no.)/Fortron-Source.
