    Good working power supply. Lots of cables easy to see labels to plug in cables. Got scared for a bit since the fan doesn’t power up until a big load is used. Otherwise quiet and heavy.

    Great PSU! Very quiet! Now I wish and wait for graphics card from the 30 series. Best buy needs to move product faster. Charter a ship to China. Target, Costco, and others have figured it out. We need some containers of cards.

    Got this after the EVGA unit I bought had coil whine, silent outside of expected fan noise while gaming. Currently supports my 3080ti which isn't light on power demands.
