Its a good looking power supply in partnership with CWT, but is it worth the money? The DQ850-M promises high performance along with 80 PLUS Gold and ETA-A efficiency levels. It uses a 120mm FDB fan, which offers quiet overall operation while the provided warranty is 5 years. Since this power supply uses quality parts including Japanese caps, it will easily outlast the provided warranty, given that you power it through a stable mains grid.
