Original PSU that came with system always crashed with certain games and under load. GPU is a GeForce 3080ti. Would have to reset using the power switch of the PSU before I could boot the computer back up. After I read about the problems with the Gigabyte PSU that came out last year I bought this one (1000GT). Runs great, silent, and no crashes. All the games that crashed now run flawlessly regardless of load.
