    Bizarre design choice not to include any straight SATA power connectors makes it impossible to use with any flush-mounted SSD; every provided SATA connector is bent at a 90-degree angle.

    Not much to say, stays quiet and Ive had no issues so far with it over this last month.

    This was what I needed for my gaming PC. Easy to install and it is very silent too!

    Best PSU i have used PERIOD Supplies your rig with efficient power, fully modular so you dont have a clutter (not sure if thats the right word but you get the idea) of cables around making your build ugly or difficult to cable manage.

    Great for your pc build that leaves you room for upgrades on gpu unless going big from the start.

    I highly recommend hiring someone to instal but it is a great purchase, noise level is next to nothing, and it looks amazing in my pc the first delivery I got was broken somehow but the second one worked perfectly fine witch was really good too know great product and well worth the money!

    Steer clear. Less than a year in and this hunk of junk started causing my PC to restart at random. Dont risk cheaping out in this department, the rest of your hardware is at risk.
