Atlas 550 User’s Manual
Atlas 550 – Quiet Mini Server Case
This case comes with a TruePower Trio™ 550 Watt power supply unit (PSU).
It complies with the newest Intel® EPS12V specification. The PSU 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 PSU 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 shut the system down.
Then turn the switch back to the ON (I) position and reboot.
Antec TruePower Trio™ power supplies feature Power Factor Correction (PFC) circuitry in accordance with European standard regulation code
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.
