The airflow is amazing! It was super easy to install all the parts inside. The cable management system inside is also super convenient 2 years passed still working perfectly.
I would recommend this to a friend!

Quiet, easy to install

Upgraded from 750W without EPS12V standard. Easy installation. Fit to my ATX CPU case without problems, like mounting screws fit properly. I did not adjust RPM fan mode, quiet operation. Power cord length is satisfactory. All cables included were good, no missing or loose or damage. Satisfied to my upgrade power supply.
I would recommend this to a friend!

I recently installed this into a new build with a Ryzen 9700 X and a Nvidia RTX 2070 super, it works well, it’s quiet and I have no complaints. Came with lots of cables for everything I need. Would recommend.
