Review: Picked this up after my former PSU, an MSI 850w, started failing and causing my computer to power down abruptly. Swapped this in and everything is working smooth as silk again. Combined with reasonable price and next-day shipping, this saved me a load of headaches (and downtime). Two cons: 1) no 12V HPWR connector for the newest video cards, it really ought to have this. And 2) the packed in modular cables are not great. It has three 8-pin 12vEPS cables (labeled "CPU") of which most users can only use one or two, and only two PCI-E cables, of which some GPUs need three. They should swap a CPU cable out for an extra GPU cable.
Review: Excelente fonte, não apresenta defeitos e suporta o computador mesmo quando este consome seus 500W~ sob full load e com picos de tensão. 10 anos de garantia da fábrica, qualidade Corsair/Seasonic. Altamente recomendado, nunca economize na sua fonte.
