Key Features

The MasterWatt 650 650W 80 Plus Bronze Semi-Modular Power Supply from Cooler Master is a standard ATX-sized power supply designed to provide your system with stable and reliable power. It can output up to 650W of power and includes all the cables you need for up to a dual graphics card build. Moreover, it operates quietly and features multiple protection technologies to keep things operating smoothly.

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.
