    A bit pricey but it will last a long rime. Comparable to the Seasonics and higher end EVGAs. Get this series, NOT the CV, which feel mush lighter and cheap. Get an 850 or better. You may need the extra juice down the line and the difference in price between a 600-750 and this one isnt much. Dont skimp on a PS.

    I am very pleased with my purchase and have to say this is a GREAT Power Supply. Robust and easily ran my RTX 2080 ti and Elgato 4k pro setup after off-brand 735w failed multiple times.

    I got this to replace a failed power supply, and am exceptionally pleased with it. While my old power supply had modular SATAPCI-E power supplement cords, the mainboard ATX connectors were hard-wired; This Corsair offering uses modular connectors for the mainboard as well, making routing, connecting, and keeping tidy the cables even better. Does what you expect of it (powers your rig), looks spiffy, modular design means less superfluous cables stuffed in odd nooks, and improved ease of installation in tight cases. Literally could not think of any design improvements, and while the last remaining concern is longevity, which takes time to assess, as this is a Corsair product I have a track record from which to draw expectations (which are that itll outlive the mainboard it serves).

    I bought this PS to replace my Corsair 750. I machine was shutting it self off and rebooting randomly and I believe that it was starving for juice. So I followed the advise of a PC guy and got the Corsair 1000 and put in about 5 fans and the problem went away.

    Power supply is perfect except the cables are a bit stiff making them dificult to cable manage. Other than that its quiet, reliable and efficient.

    Buena fuente de alimentación, lamentablemente no era compatible con mis necesidades (fue devuelta) pero sí requiriera una fuente de alimentación similar en el futuro consideraría comprar esta nuevamente.
