Seasonic G Series 450W

Seasonic G Series power supply units are 80 Plus Gold certified, which is a certification awarded to power supply units with efficiency over 87%. The ATX (revision 2.3) unit has a 450 W maximum power output and features the obligatory active PFC. The intelligent S2FC thermal circuit system (Smart & Silent Fan Control) monitors the temperature and adjusts the fan speed to keep the optimal balance between cooling and noise levels. The unit’s high-quality capacitors are manufactured in Japan, guaranteeing longer service life than other power supply series.
The unit’s connectivity includes an ATX connector 20+4 pin and 4+4 pin EPS12V cable, which are firmly connected to the device. Other cables, which include two 6+2 pin PCIe, 5x Molex, two FDD cables and six SATA connectors, are modular–they are attached separately. The power supply is equipped with a wide range of safety features in case of unexpected fluctuations in the mains supply (OVP, UVP, OPP, OCP, OTP, SCP), which are ready to intervene at any time. Another nice feature is it output voltage regulation, which keeps the rate of variation under 3%.If you are looking for a quality power supply unit with high efficiency and for a reasonable price, the Seasonic G Series is an excellent choice.

It paid to take the more expensive and more powerful source than is needed because it has massive components that should endure a noisy fan may not cool. The source is much quieter than the fans in the next plasma TV
Perfectly quiet
