★★★★★Very Reliable
Its reliable, it works perfectly with no issues, i havent encountered any whining from it, it runs 128gb ddr4 ram, a few terabytes of storage and RTX 5060 like its nothing, along with peripherals, i would recommend this for any future build

★★★★★Great PSU will be upgrading
Great PSU Cables are stiff, Had to foster of force them in the under part of my case. Will be returning only due to a better deal on amazon for a 1000W, same version, getting a new mobo and will require more power so I went with the upgrade. For for a ryzen 7 7800x3D and a 9070xt it worked great, Would like more headroom. So if your someone who has a 5060, 5070 or any 40 series (besides 4090) It’s great!
