The mother board I'm using (the SuperMicro MBD-X10SL7-F-O) to run ESXi has a BIOS setting that relates to conserving power. Presently it's set to favor performance over saving power (which is the factory default). Are there any relevant settings in ESXi also? For instance, I see under "Hardware" there is a "Power Management Settings" section. Anything else, or other tweaks, or is that basically it?
I used a Kill-a-watt type meter to measure the motherboard, together with the CPU (an E3-1230v3), Intel's stock CPU fan, 16GB 1600 1.35v RAM, a Samsung 850 250GB SSD, and an older 500watt Corsair power supply, and an 8GB USB boot stick. All that combined measured out to 41 watts with ESXi at idle and no VM's running. In contrast, it measured as drawing 6 watts when the motherboard was off but in standby
For comparison, the Kill-a-watt measured a SuperMicro C2758 motherboard as consuming about 16 watts with ESXi similarly at idle. (though with a picopsu instead of a corsair power supply).
