...anyway just wanted to know what supply provides good clean low noise rails...
most psu's will clean up a bit if you have "dirty power" or dips/spikes, but if you want to be extra safe, and have the extra cash I recommend adding a Power Line Conditioner between your outlet and all other power connections. I picked up a Tripplite 1800W PLC which not only filters EMI/RFI, but has active boost/surpress if line voltage drops or spikes. For me it was worth the investment, others may disagree. I forget how much it was, maybe like 150. The Egg didnt stock it but I got it thru CDW.
Some say you can extend the life of your psu by inserting a gate designed to handle these specific variations, sending a clean constant 120V to your psu always. Sounds like its true but I personally cant prove it.
anyway good luck
