    Apparently you get what you pay for, this power supply model has gone bad on us every 3 months. We've bought 3 of them and will not buy any more.

    It’s worked great now for 3 years. Love that it’s semi modular don’t need to keep track of a ridiculous amount of extra cables.

    good psu for the money

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I have been using this psu for a year now and during that time I have had zero issues. I have found it to be very stable, stays in good temp and voltage range and is quiet. This is in an older pc running an overclocked i7 4770k, amd rx480, 2 hdd, 1 sdd , dvd as well as multiple usb ports in constant use and as I said have had zero issues. Have used many Corsair psu's over the years and have found them to be very good quality and very reliable, this unit is no exception and I would recommend this to anyone building a mid range system.

    Excellent for the price!

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I'm building a new PC slowly and ended up getting this earlier than planned as it was literally over 50.00 cheaper than the other sites. Even better was ready in an hour at my local store! Just this weekend between this normal price and a price match on another item BB has saved me over $140.00! The local staff is always great for curbside pickup. Technically now: Corsair is a great brand. This PS comes with all the proper connectors for a mid-high end PC and a great price. Solid wattage for all but the most extreme users and even some of them. Great value and great price!

    I bought the power supply a few months ago for my new PC build, at it was great. Modular with lots of cables to hook up all your things. A great value, and has been keeping my PC running ever since.

    Good but noisy

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    It's a good inexpensive semi-modular power supply but the fan is a bit too noisy for my application. My computer is about three feet from me while sitting at my desk so I can hear the fan noise. It's more like a ticking noise rather than the rushing of air like my current power supply. Other than that it's decent so I would still recommend it if a little noise won't bother you. Not all the cables are braided either. I guess that's why this is bronze rated instead of gold.

    Not-so-fine Whine

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    The power supply in my 3-year-old Dell XPS8700 tower computer started to make an unbearable, high-pitched whining noise, so I figured it was time for a new one. I like the modular feature of this unit, which eliminates unnecessary cables. But in spite of the promises of quiet operation, the fan in the Corsair whined just as badly as the old unit I was replacing. Back it went, exchanged at Best Buy for an EVGA 600W -- much quieter, although non-modular, with unneeded cables going all over the place.
