Cooler Master MASTERWATT 650, SEMI-FanLESS Modular 80 Plus Bronze
Check availability
80 Plus Bronze
The 80 Plus Bronze certification guarantees that MasterWatt delivers an average efficiency of 85% at full load.
Durable LDB Bearing Fan
This power supply is built with a Cooler Master 120mm Silencio FP fan, which combines sealed LDB (Loop Dynamic Bearing) bearings with quiet fan blades for durable, quiet cooling.
Semi-Fanless Operation
The MasterWatt operates silently at 0 dB when under 15% load. Past that, the fan starts spinning to dissipate heat.
Dual Forward & DC-to-DC Circuit Design
The Dual Forward and DC-to-DC circuit design offers reliable and stable power that's especially significant in +3.3 V and +5 V outputs.
More Conductive PCI-e Cables
The MasterWatt uses 16 AWG PCI-e cables for less resistance and better efficiency.
Protection
- OCP (Over Current Protection)
- OVP (Over Voltage Protection)
- UVP (Under Voltage Protection)
- OPP (Over Power Protection)
- OTP (Over Temperature Protection)
