Physical specifications — microtower model

Dimensions

Height: 444.5 mm (17.5 in.)

Width: 165.1 mm (6.5 in.)

Depth: 497.8 mm (19.6 in.)

Weight

Minimum configuration as shipped: 9.1 kg (20 lb)

Maximum configuration: 10.2 kg (22.5 lb)

Environment

Air temperature:

System on: 10° to 35° C (50° to 95° F)

System off: 10° to 43° C (50° to 110° F)

Maximum altitude: 2134 m (7000 ft)

Note: The maximum altitude, 2134 m (7000 ft), is the maximum altitude at which the specified air temperatures apply. At higher altitudes, the maximum air temperatures are lower than those specified.

Humidity:

System on: 8% to 80%

System off: 8% to 80%

Electrical input

Input voltage:

Low range:

Minimum: 90 V ac

Maximum: 137 V ac

Input frequency range: 57–63 Hz

Voltage switch setting: 115 V ac

High range:

Minimum: 180 V ac

Maximum: 265 V ac

Input frequency range: 47–53 Hz

Voltage switch setting: 230 V ac

Input kilovolt-amperes (kVA) (approximate):

Minimum configuration as shipped: 0.08 kVA

Maximum configuration: 0.3 kVA

Note: Power consumption and heat output vary depending on the number and type of optional features installed and the power-management optional features in use.

Heat output (approximate) in British thermal units (Btu) per hour:

Minimum configuration: 257 Btu/hr (75 watts)

Maximum configuration: 789 Btu/hr (230 watts)

Airflow

Approximately 0.79 cubic meters every three minutes (28 cubic feet every three minutes) maximum

Acoustical noise-emission values

Average sound-pressure levels:

At operator position:

Idle: 38 dBA

Operating: 43 dBA

At bystander position - 1 meter (3.3 ft):

Idle: 33 dBA

Operating: 37 dBA

Declared (upper limit) sound-power levels:

Idle: 4.8 bels

Operating: 5.1 bels

Note: These levels were measured in controlled acoustical environments according to the procedures specified by the American National Standards Institute (ANSI) S12.10 and ISO 7779 and are reported in accordance with ISO 9296. Actual sound-pressure levels in a given location might exceed the average values stated because of room reflections and other nearby noise sources. The declared sound-power levels indicate an upper limit, below which a large number of computers will operate.

Note: The computer is classified as a Class A or Class B digital device. See the Quick Reference for further information about this classification.
