Our colleagues from Anandtech just put online an article facing-off not less than 11 power supplies with this common feature of all: be rather entry-level models and offering power ratings from 350W to 450W.
It includes, for example, the Corsair CX430 V2, or the Enermax 450W NaXN, the Be Quiet! System Power 350W and other references like Thermaltake, FSB, or even Rasurbo Rosewill and Sinan. Which ones are unable to take their game well?
