Hardware Secrets posted a review on the Ultra LSX 750 Power Supply

The new LSX series from Ultra so far features only two models, 650 W and 750 W, both with 80 Plus Bronze certification, single +12 V rail, synchronous design with DC-DC modules for the +5 V and +3.3 V outputs in its secondary, and lifetime warranty (if you register the product after buying it).
