yep it does work on the 480 tgu01 , just did it theres a little pot on a board turned it a bit and volts went upto 12.35 , 5.16 , 3.29. dosent seem to bother the psu as the smart fans are still spinning slowly. got a pic of the pot but its crappy quality. but the pots easy enough to find , its kind of a creamy white ish color
