A quote from the article:
Antec TruePower Quattro 1,000W Power Supply Review
The Antec Quattro 1,000W power supply has a lot of very good features. The voltage regulation is excellent and the overall efficiency is very good. Under normal operating conditions (below 600W load) the Quattro 1kW is quiet and runs relatively cool. The Quattro comes fitted with a good balance of hard-wired and modular connectors that can support dual, high-end video cards. And let's not forget active PFC and Antec's 5-year AQ5 warranty!
