Have you measured the power consumption of your "high power consumption" server?

Seriously. You can get running states around 1W these days.

Running states around 1W? How?

1W is a unicorn as just plugging in a power supply with no PC parts hooked up will register 1W. <10W is more realistic. Select a PC that can run off a laptop charger. Check manufacturer spec sheets for the idle power consumption. Don't install any PCIe cards or hard drives. Use powertop --autotune.

(looking at my 330W laptop charger)

I’m not sure that is the constraint you think it is.

To be more specific a 65W or 90W laptop power supply.
