Virtual-Hideout posted a review on the Antec Signature 850 Watt Power Supply

You can find the Signature 850 Watt Power Supply for $230.00 at retailers like Newegg and Performance-PCs. That's not a bad price at all given the internal improvements made to the new Signature line. And besides, you're buying a product from a proven name in the PSU industry. And if that doesn't entice you, how about a 5 Year Warranty? They're that confident about this product. Why shouldn't you be? Until I see something better come along, this is my top recommended power supply in the 800 to 900 watt range.
