OCIA.net has posted their review of the BFG Tech MX 550w Modular Power Supply

Last week I took the BFG Tech MX 680w Power Supply out for a spin, which earned our Seal of Approval based on several different criteria. The unit was rock solid stable, silent, modular and would look great in most any system. But for the user on a budget or those not into hardcore gaming, the 680 watts offered is simply overkill. If you fall into this category, have no fear, as BFG Tech has something right up your alley, the MX 550w PSU. Virtually identical to its 680w bigger brother, the 550 unit we have on the test bench today is about $25 cheaper, money that could be put towards other hardware or simply stashed away for a rainy day. Will the smaller MX 550w be able to follow in the footsteps of the beefier 680 model?
