The Cool Master MasterWatt 550 Plus Bronze is a true performance giant for a low price. With its compact shape, it fits in almost every case. It provides sufficient power for common CPUs and graphics cards with its 550 watts total output power. The powerful 12 volt rail delivers 45.8 A of power. Despite this impressive data, the MasterWatt 550 Cooler Master is extremely efficient, which also results from the use of high-quality components such as the capacitors. The 80 PLUS Bronze-certified exceptional power supply achieves an efficiency of up to 85% at a load of 50%.
Cooler Master has donated an excellent and quiet fan to this efficient power supply, which does not start until the power supply is more than 15 percent used. However, the 120mm Silencio FP delivers impressive numbers in operation. Thanks to the LDB (Loop Dynamic Bearing) with its protective oil, it runs very quietly and is well protected against dust.
Of course, the Cooler Master MasterWatt 550 has enough cables for extensive connectivity. In addition to the obligatory 24-pin ATX connector and a 4 + 4 pin for the CPU, there are two PCI-e-6 + 2-pin connectors for graphics cards. In addition, the power supply has six SATA and two 4-pin Molex connectors. There is also a port for floppies available.
It's almost superfluous to mention that the MasterWatt 550 Plus Bronze Cooler Master has all the necessary protection circuits that modern high-end power supplies naturally have to offer. If the PSU nevertheless bless the time: no problem, because Seasonic gives this exceptional product a full five-year manufacturer's warranty!
