BFG MX-550 Power Supply

Finally, a Modular Power Supply for Everyone!
BFG Tech® combines high performance, high efficiency, and low noise all in a modular power supply worthy of the BFG name. Modular means you use only the cables you need to improve air flow and keep your system organized. The MX Series feature a typical efficiency of up to 85% — which means 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 120MM fan in response to load and temperature. An 80MM "helper fan" only kicks in when temperatures reach over 50°C to ensure maximum performance, longer life, and low noise at lower temperatures. Quad +12V rails, over-volt, over-current and short circuit protection provides rock solid reliability and safety.

Modular design allows removal of unused cables
Includes three PCI Express® Connectors for Multi-Graphics Card Support
Features new 8-Pin PCI Express Connector
Quad 12V Rails

ATX12V 2.2
Supports the latest Intel® and AMD® based platforms requiring 24-Pin motherboard and 4-Pin or 8-Pin 12V connectors. With the 20+4-Pin motherboard connector, it is also backward compatible with previous ATX standards

Quad 12V Rails
By splitting the +12V source into four separate rails, your components are provided the most stable power available while upholding rigorous safety standards

PCI Express® Ready
The PCI Express power connectors ensure compatibility with many high-end and several dual graphics card configurations without having to use unreliable, often performance hindering adapters

SATA Connectors
Eight serial ATA connectors allow you to connect up to eight serial ATA devices without needing special adapters

BFG Thermal Control Technology
During regular operation, the fan slows down to reduce unnecessary noise

Protection Circuitry
Built-in protection circuitry is able to handle common power irregularities such as over-voltage, overload, and short circuits

A mean time between failure rating of greater than 80,000 hours guarantees a long lasting and reliable source of power

High Efficiency
While most computer power supplies pinnacle at 80% effciency, the BFG MX Series is typically 80% to 85% effcient, which means more power drawn from the outlet is converted to DC power for your computer than many of the other units on the market.
