Hello, I have 4 blade servers with a total present power of 5250 watts. Is the formula I should follow to calculate the total monthly KW/h consumption as 5.25 x 24 x 30 OR 5250 x 24 / 1000 x 30?

Assuming they’re running at their rated 5250 watts, which they’re probably not:
5250 watts x 24 hours = 126kWh per day. PER DAY!
126kWh x 30 days = 3780 kWh a month, which is approximately four times my entire domestic electricity consumption (including my own home lab, operational network, two EVs and heat pumps).
That is preposterous and ruinous financially. You do not want to do that, I promise you.
They almost certainly won’t be running at their rated maximum power, but even 20% of that run 24/7 is still a ruinous amount of electrical load. Unless your power is somehow free, you want to think very seriously before deploying that.
