# MX204 Power Planning

## Power Consumption for an AC-Powered MX204 Router

Use the information in this topic to determine the power consumption for your router and plan the amount of power you need to provide to the router.

### Power Requirements for MX204 Components

Table 1 lists the power requirements for various hardware components when the router is operating under typical and maximum voltage conditions.

Table 1: Power Requirements for MX204 Components

Component

Power Requirement at 25° C (Watts; Typical)

Power Requirement at 55° C (Watts; Maximum)

240 W

280 W

Table 2 lists the power requirements for the fully configured AC-powered routers operating under typical voltage conditions.

266 W

Table 3 lists the power requirements for the fully configured AC-powered routers operating under maximum voltage conditions.

311 W

### Calculating System Thermal Output

After you have calculated the power consumption for your configuration, you can use that information to determine the system thermal output (BTUs per hour). To do so, multiply the power consumption in watts by 3.41.

For example, in Table 2 we calculated the power consumption for a fully configured chassis running at high activity at 25° C typical temperature to be 240 W. Using that information we can calculate the system thermal output for the configuration:

```Power consumption in watts * 3.41 = system thermal output in BTU/hr
240 W * 3.41 = 818.4 BTU/hr
```

## Power Consumption for a DC-Powered MX204 Router

Use the information in this topic to determine the power consumption for your router and plan the amount of power you need to provide to the router.

### Power Requirements for MX204 Components

Table 4 lists the power requirements for various hardware components when the router is operating under typical and maximum voltage conditions.

### Calculating System Thermal Output

After you have calculated the power consumption for your configuration, you can use that information to determine the system thermal output (BTUs per hour). To do so, multiply the power consumption in watts by 3.41.

For example, in Table 5 we calculated the power consumption for a fully configured chassis running at high activity at 25° C typical temperature to be 240 W. Using that information we can calculate the system thermal output for the configuration:

```Power consumption in watts * 3.41 = system thermal output in BTU/hr
240 W * 3.41 = 818.4 BTU/hr
