Antec Basiq User’s Manual

ATX12V version 2.01 power supply

Model: BP500U

Antec Basiq series power supplies are built to be compatible with the ATX12V 
version 2.01 specification. They include dual 12V output circuitry that delivers 
safer and more reliable output to your system’s components, as well as higher 
energy efficiency, which reduces power consumption by up to 25%, saving you 
money on your electricity bill. In addition we’ve included a variety of protective 
circuitry: OPP (Over Power Protection), OVP (Over Voltage Protection), and SCP 
(Short Circuit Protection).

BP500U includes Universal Input with Active Power Factor Correction (PFC). 
Universal Input allows you to connect your Antec Basic power supply to any AC 
power outlet between 100~240V without having to worry about setting a voltage 
switch. Active PFC improves the power factor value to the power supply by alter-
ing the input current wave shape, helping the power plant provide power to users 
more efficiently.

Power Switch

: This power supply comes with a main power switch. Make sure 

you turn the switch to the ON ( I ) position before you boot up your computer for 
the first time. In normal operation there is no need to turn the switch to the OFF 
(O) position since the power supply is equipped with a soft on/off feature which 
turns your computer on and off through the soft switch on your computer case. 
You may need to turn the switch to the OFF position occasionally should your 
computer crash and you cannot shut it down through use of the soft switch.
