Ultra X4 850 W Power Supply

Link

"Ultra is a traditional power supply manufacturer and the first to come with the modular cabling system idea (which led the company to sue all manufacturers that launched power supplies with a modular cabling system, including Antec, Thermaltake, FSP, CWT, Seasonic and Corsair, just to name a few). Today they are launching a new series called X4 featuring a complete modular cabling system and single-rail design. Let's see if the 850 W model from this new series is a good buy. Power supplies from X4 series are manufactured by Andyson. The only other power supply from Andyson that we ever tested was BFG ES-800 (note that BFG uses other manufacturers besides Andyson)."
