9070 xt red devil undervolt powersave

Been messing around with undervolting shaved off almost 100watts from the wall. 7600x3d CPU msi tomahawk b650 ddr5 6000mhz. -75mv undervolt and -20% power limit. Ran stress test in 3mark and passed. Only the computer is connected to watt meter. I estimate 100ish watts are the motherboard and cpu etc. as that how much it uses when the gpu isn’t being used. So that means you can save 100watts almost from stock with minimal performance loss. Undervolt and power limit score is 21944. Stock score is 22109
