Nice, affordable powersupply. The fan is pretty silent, and everything works fine. The 24 pin connector cable could have been a couple of inches longer , but it worked fine for my setup

### ⭐⭐⭐⭐⭐ Quiet and effective
*by M***G on May 31, 2021*

Replaced exact same PS - the first gave out after five years, possibly due to fine drywall dust getting in when doing some minor repairs. The new one works great and is much quieter. Hoping for a long life.
