Repeat the previous multimeter procedure to obtain those three digit voltage numbers. However, before measuring the red, orange, and yellow wires, first setup the machine to actually see a supply defect.

IOW download from the internet, while playing complex graphics (ie a movie), while searching the hard drive, while powering some USB devices, while reading a CD-Rom, etc. When the system is multitasking, measure any one red, orange, and yellow wires. Then report voltages from the six wires to see if the supply is sufficient. So that the defect need not become obvious after its warranty expires.
