Zero RPM PSU for NAS

[ice_hiboy]

So I have a Xpenology NAS built in a Fractal Node 304. Right now I have CX 430 that I had laying arround. I would love to have a PSU where the fan dows not spin before it needs to. Right now the PSU is the one thing making noice when idle. Idealy modular so I can skip the pcie cabel, since no video card. But some sata and molex would be nice. It can fit 6 drives, althoug only 4 sata on mobo. Right now there is 3 drives and a 4 one comming.

Anny ideas? Dont really wanna buy a RM550i since it will never reach that power level and its a lot of money.

There are several manufacturers that make Fanless PSUs as well as PSUs with a Hybrid mode, where the Fan does not kick on until about 30% load on the system.  The main one that comes to mind is the Seasonic 520FL but it is a bit pricey.

Also the node is rather small. So not to big

Unfortuantely most of the zero fan, or eco fan mode PSUs are going to be relatively expensive... they also spin up the fans depending on % PSU draw/temp, so if you have a system that pulls 200W for instance you'd need maybe a 500W one, if it draws far less then can obviously get a lower wattage one. I would suggest though that you go with a 550W EVGA g2/3, that should be more than enough headroom for the fan to remain silent or spin up rarely (depending on other cooling you have), they are Here

A bit pricey at $80, but come with 10 year warranty IIRC.
