## Re: wattage calculation

Hi Zung,

The MAX utilization is ..

power=voltage*current

hence...

it is 202*30

==> 6080watts ==> 6KW ( kiloWatt)

## Re: wattage calculation

but I almost sure that your equipment doesn't use 30A. You should ask your hardware vendor or read owner manual for real numbers.

## Re: wattage calculation

usually, power wattage is a product of VA and power factor:

Watt = VA * power factor

for electronic devices, power factor is usually 0.8. so, in your case 6KVA or 4.8 KW is the calculated requirement based on your inputs.

## Re: wattage calculation

average power consumption for a given box is rather like the question "how long is a piece of string?" you can only _really_ know by actually measuring it as it will vary based on configuration - how many discs in the thing - how much memory, how many and what type of I/O cards, how many CPUs etc etc etc

having said that, some of the system specs have a "typical" entry in them, but then, what might be "typical" for the spec creators may not be typical for you.

if the system were 120 V and < 1850 watts, you could connect a P4400 "Kill-A-Watt" meter to the thing and measure it. alas, the "Kill-A-Watt" doesn't do > 120V AC so you have to look into a more "hefty" (and more \$\$) watt meter.
