Conclusion: So earlier this year I took a look at the Quattro 850 and now I've had a chance to take a look at the Signature series. So what do I think? Antec has a great power supply with the Quattro 850 but the Signature's quality is a cut above. There is room for improvement still though, the half modular design is frustrating and the thickness of the cables makes it difficult to hide the wiring when doing a build.
Excerpt: Antec came to me the other day with a product and a promise. They told me they would let me have a look at their new flagship power supply, the SG-850, and promised me the world in performance. Come on in and see how she did.
Excerpt: The Signature is a top-of-the-line high performance power supply, available in 650 or 850 Watts and are compatible with ATX12V v2.3 and EPS12V v2.91 standards. Designed to appeal to system builders looking for a truly premium power supply, the Signature uses cutting-edge features, several of which have never before been offered in a consumer power supply.
Excerpt: La serie Signature , formada por los modelos 650 y 850 , que hemos probado, incorpora un conjunto de tecnologías que no habían sido aplicadas, hasta ahora, a fuentes destinadas al consumo “doméstico”.
