    Bought this as a secondary option as the power supply I was originally going to go with was on back order. This one was the more expensive choice but im kind of happy I went with this one! So far it’s been working for over 3 months perfectly fine. Quiet and made well. No complaints!

    Out of the box it had a weird odor to it that faded after a day or two of usage. The cables were a bit short for my old HAF case, but was able to get them plugged in. I've had this running ~24/7 for the last 2 weeks and it stays cool and silent while powering 2 gpus.
