    I had to return because it was super small for my case, this is meant for smaller cases. I have the Gamdias Talos M1B ARGB. SO if you have larger cases dont pick ATX. For the price, it has really nice specifications and have corsair products and had no issue.

    Picked this up to power an EVGA FTW3 RTX 3080, one of the more power hungry 3080s out there. This PSU works great and is very quiet.
