    Great for the price

    Bought because my previous psu died. Works perfectly and was easy to install. Love that it came with the new connector for Nvidia 50xx gpus!

    Power Supply

    A very strong PSU. I had an issue with my cables and connecting to a new gpu and I frantically drove to bestbuy 30 mins before closing and they had it. Not only with it imminently in stock but the power and performance of this unit is remarkable.

    Its a power supply alright

    It's really hard to talk about or rank a power supply among other power supplies. For one, they require a long time to know if there's problems. Second, they're inside of your pc, and if there is a smaller issue, usually you won't feel it. I needed a new power supply since the fan on my old PSU burnt out. This one gives more power than that one and matches with my hardware better. It keeps it powered, theres no throttling on my cpu or gpu, and its way more quiet than my 2018 PSU was. Really if you need this level of power and need a new power supply you can go for worse, and the price point is honestly pretty good. Really if you're looking at reviews of your PSU the only thing you should be ware of is a bunch of reviews saying it blew up their pc.
