    Modularity made my cables much easier to deal with. I always liked corsair stuff.

    I just did a new ATX PC build a couple months ago and went with this PSU. So far Im very happy with it. Unlike one other reviewer, mine came fully and professionally packaged. Keep in mind this review is for a PSU that is way over what I need for power in my case - perhaps some of the negative reviewers where it died in a few days needed a higher wattage one.

    The power supply came a lot faster than expected, and the power to price ratio is a no brainer. Easy to install and does the job

    It’s great for saving energy and it only turns on fan if needed if to warm and good for the price

    Greater than one week

    Worked well for three days after installation. It was installed correctly and given sufficient airflow. A couple days later, my PC wouldn’t turn on. I started trouble shooting and eventually removed the PSU. I used a PSU tester and, unfortunately, there was no fan spin. The unit was dead. I returned the unit for a refund.

    Power supply was slightly longer than one removed but fit in slot nicely, only reason i didnt give 5 stars was the lack of proper instructions for installation, plugged my new video card in what was supposed to be a peripheral port & found it was for cpu so first time operated computer tried to boot from video card, is otherwise very quiet & operates well
