NSK 4000 / 4480 / 4480B

Super Mini Tower Case

This case is designed to meet Intel’s Thermally Advantaged Chassis (TAC) design guide requirements.

The NSK4000 Case Only

NSK 4000 comes without a pre-installedpower supply unit (PSU). This allows you to install your choice of Antec power supply to match your individual needs.

The NSK4480 Case with EA-380power supply

NSK 4480 and NSK 4480B come with an EarthWatts 380 watt PSU. Universal input, active PFC single 80mm fan cooled power supply that follows the ATX12V version 2.2 specifications. This includes dual +12V output rails that deliver safer and more reliable output to your system’s components. Featuring higher energy efficiency, which reduces power consumption by up to 25%, saving you money on your electricity bill. EarthWatts’ power supplies have achieved 80 PLUS® Certification, the latest independent standard in power supply efficiency.

n addition EarthWatts includes a variety of protective circuitry: OPP (over power protection), OVP (over voltage protection), and SCP (short circuit protection).

The power supply comes with a main power switch. Make sure you turn the switch to the ON (I) position before you boot up the computer for the first time. Normally, you won’t need to switch to the OFF (O) position, since the power supply includes a soft on/off feature. This lets you turn the computer on and off by using the soft switch on the computer case. If the computer crashes and you can’t shut it down using the soft switch, you can switch the main power to the OFF (O) position, to clear the fault, then reboot.

For models designed for sale in the European Union:

Antec power supply models feature Power Factor Correction (PFC) circuitry in accordance with European standard regulation code EN61000-3-2.By altering the input current wave shape, PFC improves the power factor of the PSU. A better Power Factor increases energy efficiency, reduces heat, improves output voltage stability and prolongs the life of all equipment. The PSU’s high efficiency design and the quiet fan deliver not only a cleaner but also a quieter operating environment.


Although care has been taken to prevent sharp edges in your Antec case, we strongly recommend taking your time and the appropriate care when working with it. Hurried or careless motion and use of excessive force, particularly when you are working in areas you cannot see clearly, are but a few examples of activity that should be avoided. Please use reasonable precaution.

Cooling System

The Rear Exhaust TriCool™ fan:

The NSK 4000, 4480 and 4480B come with one 120mm TriCool™ fan preinstalled. This fan has a three-speedswitch that lets you choose between quiet, performance, or maximum cooling. (See specifications below.) The fan is installed so that the air is blowing out of the case. Connect a large4-pinconnector from the power supply to the male4-pinconnector on the fan.

Note: The default setting of the fan is Low. We recommend this speed for maximum quiet computing.


Note: The minimum voltage to start the fan is 5V. We recommend that our users to set the fan speed to High if you choose to connect the fan to a fan control device or to theFan-Onlyconnector found on some of Antec’s power supplies. Afan-controldevice regulates the fan speed by varying the voltage to it.

The voltage may start as low as 4.5V to 5V. Connecting a TriCool™ set on Medium or Low to a fan-controldevice may result in the fan not being able to start. The already lowered voltage from the fan control device will be further reduced by the TriCool™ circuitry below 5V.
