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.

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.

Really well made product. Just for a good set up. I paired it with a i7 13700k and a 4070 super with around 8th fans. Works really good with no issues. It is quiet and will allow an upgrade for a 5080 or something like that. Really good one

Quise cambiar de fuente de poder porque la que tenía (una básica genérica) empezó a hacer un ruido extraño e insoportablemente molesto. La mayoría de mis componentes han sido Corsair, es una marca por la que bien puedo meter las manos al fuego, todo ha sido de muy buena calidad. Y esta fuente no fue la excepción. Al encender mi PC con esta nueva fuente "rugió" por unos segundos y después trabajó en silencio, incluso mientras juego. Su nivel de ruido es apenas perceptible, nada que te afecte al micrófono o tu teléfono para llamadas. El diseño es muy simple, a diferencia de otras que son más vistosas, pero bueno, hay gabinetes que la cubren por completo y eso ya no es un inconveniente.
