You can clearly see that the Foxconn system’s idle power is a few watts below the minimum power requirement of the Gigabyte system, both using exactly the same hardware. Peak power, however, is similar; this is because of Gigabyte’s four-phase voltage regulator, which is more efficient at high loads.
