The new TruePower (TP) series from Antec is based on a DC-DC converter on the secondary, i.e. it is basically a +12 V power supply with two small power supplies in charging of converting the +12 V output into +5 V and +3,3 V. This is the same concept used on power supplies series like Signature also from Antec, M12D from Seasonic, UCP from Cooler Master and HX (750 W and above) from Corsair. These other models proved to have an above-the-average efficiency. It is important to keep in mind that Antec used to have another series using the same name, but using a completely different internal design. That is why Antec is using the word "New" after the name "True Power".
