BFG offers several different models of power supplies, from the value-oriented GS to the modular MX series, all the way up to their top of the line ES-800; they have something for every need and budget. The one I have for review today is the LS-550, which seems to fall somewhere in the middle of their lineup. Despite the relatively smallish power rating, the LS-550 offers quad +12v rails, 6 and 8-pin PCIe and ATX 2.2 version compatibility, all backed up by an impressive 5-year warranty.
