Antec's TruePower Classic series sets new standards for power supplies. TruePower Classic is one of the first series to comply with the tough energy standard, ErP Lot 6: 2013. By using a PSU that is 80 Plus Gold certified, operating up to 92% efficient, you can reduce your electricity bill by up to 20% when compared to many other power supplies. 2 high current rails and a 100% +12 V output ratio maximize TP-650C's capabilities to power the CPUs and GPUs. TP Classic's PhaseWave design is a server-class LLC design with a synchronous rectification based on a DC-DC topology. Japanese capacitors achieve unprecedented tight voltage regulation and low ripple and noise to maximize your system's performance. Antec's intelligent thermal manager fan control spins the high-quality 12 cm DBB fan optimally to cool your PSU quietly. CircuitShield makes the TP-650C safe and reliable in any environment with its eight industrial-grade protections.
