3.3VI / O voltage needed by motherboard, while AT power supply has only 5V and 12V
output, because ATX power does not completely interrupt after shutdown, so the computer
will be able to achieve a soft boot, MODEM wake function. As regards to the power of the
power supply, you can generally choose about 450W ATX Power Supply. Please note that
poor power quality failure may lead to damage to the motherboard, CPU, Memory, hard
