"Not long ago, I looked into a new line of units from BFG Tech, the LS series. Today, I'll have a look at the 550W model and see how it performs compared to the 680W. Efficiency is given as greater than 80% typical, and though they don't mention it, this model is 80 Plus certified. You will recall that big brother didn't quite manage to pull that off, and I'll be interested to see what happens on the load tester with this unit. Come in and join me, won't you?"
