PC Stats has posted a review on the HEC Ace Power 580UB 580Watt power supply

This all-black dual-fan PSU pumps out a maximum output (peak) of 580Watts, which should be quite sufficient for SLI and just about anything else you can throw at it. The power supply uses two discrete +12V rails to separate motherboard and videocard power flow. The Ace Power 580U also features a large array of connectors, including dual 6-pin connections for powering a set of SLI videocards. Obviously, the HEC Ace Power 580UB is designed with the possibility of an SLI system in mind, and would be quite suitable for that role.
