The new Revolution85+ power supplies from Enermax were designed to deliver clean, stable outputs with high efficiency and minimal noise. The Revolution 85+ series comes in four different wattages: 850W, 950W, 1050W, and 1250W – although the last will only be available for 230VAC.
Revolution85+ power supplies are some of the first to be certified under the new 80 Plus Silver classification to be at least 85% efficient at 20% and 100% of the rated output and at least 88% efficient at 50% of the rated output power. continue reading…

ST1200 power supply is an excellent power supply which can reach 1200 Watt output with efficiency greater than 80% and with 100% modular cable system. Its full array of amenities such as dual PCI-E 8pin, six PCI-E 6pin, and six SATA connectors can support various power usage and up to three high-end graphic cards easily. Cooled by a quiet 135mm fan, the ST1200 is an awe-inspiring power supply with exceptional stability and optimal efficiency. continue reading…

The GPMP0901 12V, 12 Amp switching power supply is great for a wide range of applications as it is capable of maintaining 12 amps output current at 12V DC.
The ElectriFly 12 Amp switching power supplies accepts power from a 110V AC source. This is a “switching” power supply as opposed to a linear power supply which employs a high frequency switch-mode design to convert 110V AC input to a fi xed 13.8V DC output. This stateof-the-art technology allows the power supply to operate entirely without a big, heavy internal transformer and results in a very small, and lightweight device that can deliver a tremendous amount of power. This technology also generates highly effi cient and clean DC output. This is especially valuable today as many R/C chargers utilize peak detection designs which are very sensitive and demand the cleanest power sources possible in order to maintain error-free operation. continue reading…

BFG LS-550 power supply is part of BFG’s LS Series which features a typical efficiency of up to 85% so more power is converted to DC than many other power supplies on the market.
BFG Thermal Control Technology ensures that the unit runs as quietly as possible by varying the speed of the fan in response to load and temperature.
Single +12V rail, over-volt, over-current and short circuit protection provides rock solid reliability and safety.
LS550 power supply works with AGP, PCI, PCI Express®, includes two PCI Express Connectors for Dual Graphics Card Support and features new 8-Pin PCI Express Connector. continue reading…
