2 years ago I bought a pre-built gaming computer with a RTX 3060. From the start it crashed during heavy game play. I replaced a few parts and even sent the GPU back for a replacement. Nothing fixed it and I just assumed that crashing once or twice a day was normal. Ever since upgrading with this power supply about a month ago, I've had zero crashes.

650w Bronze is a great bang-for-the-buck slot in the power supply game for this price point, and can't beat a 5-year warranty!
