Link: Tagan TG480-U01 480w PSU

[JN]

"The Tagan TG480-U01 480W Power Supply is a heavy-weight PSU. As well as having a massive 480w of power output, the PSU is whisper silent for the majority of the time. This is thanks to the Tagan Silence Control Technology, which allows for whispering operation of only 21dBA (up to 50% load)."
