TechAddicts posted a review on the BFG ES Series ES-800 800 Watt Power Supply

This power supply would be perfect for anyone looking to build a quad core system with multiple video cards, especially because it offers SLi certification for up to two NVIDIA 8800 GTX's. At around $170, this power supply has great performance combined with high quality parts; with the lifetime warranty and 24/7 technical support, it is hard to find another power supply that offers the same peace of mind and performance.
