Enermax Reveals A Fanless 650W PSU

[smeezekitty]

[citation]Semi Passive has big problems , if your power usage is in the "critical" area where the PSU starts up the fan , it will switch on/off like crazy and very annoying.

I prefer it to be user controllable ... that is , if it happens , the user can turn off the semi passive controller.[/citation]
Something called hysteresis can fix that.

[citation][nom]makaveli316[/nom]My psu has a fan (Corsair 650hx) and i never hear it.I think my room noise is more loud than it.With that in mind, what's the point of a fanless PSU?Are there really people having sound issues with their psus?[/citation] The point is for a dead silent PC for example a in DAW home studio so you can record a microphone input without fan noise looking into the recording.

Normally professional studio's have a control room for that purpose and a recording booth that's silent, but that's exactly always a option for home studio's.

Also anyone that just wants a silent PC in general or a fault tolerance one that they don't need to worry about fans cooling or needing routine cleaning not to mention most silent PSU tend to also be very efficient as well.

Simply put if you turn on your PC and you hear more noise then before you turned it on it's not silent even though it might be considered quiet.
