Summary: It was beginning to seem like manufacturers wanted enthusiasts and gamers to think they needed power supplies with extremely high total power ratings in order to keep their systems up and running. While these high powered units may have a (small) market, you can definitely power a modern system with a quality power supply with a much more reasonable total power rating. The LS-680 680W power supply is a perfect example of this.
Pros: » No nonsense appearance looks sharp, » Plenty of connectors, including four PCI Express and eight SATA, » Solid performance, » 20A on each of four 12V rails, » High efficiency, » Runs cool and quiet, » Well finished cables with black mesh sleeving and black connectors, » $90 (US, after rebate)
Cons: » Somewhat generic and undersized internal components, » Price only gets competitive after $25 mail in rebate
Summary: To test the BFG Tech LS 680W power supply, I measured the 3.3V, 5V, and 12V output to the motherboard at idle and load with my Craftsman multimeter. A load situation was created with F@H SMP running on the processor for a nice 100% CPU and heavy RAM load, a CD copying to the storage drive, while the main drive defragmented, and ATI Tool was running 3D visualization on the GPU.
