I have a T4-4 server with 2 CPUs.  I need to calculate the power I need but I'm only going to plug in 3 of the power supplies, since only 2 are needed to run.  The specs have these figures : T4-4  = Power Supplies • Four hot-swappable AC 2,060 W redundant (2   2) power supplies • Maximum operating input current at 200 VAC: 14.6A • Maximum operating input power at 200 VAC: 2770W.  I know there is a power-calculator link for the T4-4 but it doesn't let you select only 3 supplies.   I see the T4-2 has these specs,
