Or not.
Say 50W difference for a 24*7 server.
That's around 1.2Kwh/day.
Boiling 1 cup of water will use around 55Wh.
You can make around 44 cups of coffee with the saved electricity.
Electricity is quite expensive in some places.
While you can get power supplies for $9(us), which will work fine, a
saving of 50W/24*7 would save me around $62(us)
If a power supply lasts 3 years in a server, then it might be worth
considering power supplies up to over a hundred (us) dollars, if they
may save electricity.

You can boil an extra 22 liters (5 gallons) with the saved electricity.

TVs generally use around 60W, to save as much you'd need to be on the
pot for 20 hours a day.
