BUILT WITH THE TUF STUF
The 80 Plus Bronze rated MasterWatt TUF Gaming Edition PSU offers semi-fanless operation, modular cabling, thicker than standard market cables, and a 5 year warranty. While under 15% load, MasterWatt TUF Gaming Edition fans aren't spinning, thus reducing the noise, power consumption, and wear on the unit. When the fan is spinning, the Cooler Master designed LDB to fan bearing delivers low noise and a long lifespan. A gradual fan curve increases cooling based on the system's needs, keeping the noise level in check. The higher heat tolerance of the 16 AWG PCI-e cables deliver increased efficiency due to the higher current allowance.
