The model is positioned by the manufacturer in the middle price range and can serve as a good choice for powering a powerful and performant gaming computer. So, this model has operational characteristics at the level of "80 PLUS GOLD". But the power supply did not pass independent certification, which explains that the Chieftec A-90 GDP-650C belongs to the most affordable price range (in the “80 PLUS GOLD” category). The efficiency of this model is excellent 90%. The operation of the power supply is built on the basis of innovative DC-DC voltage conversion technology. Circuitry of this type can be safely trusted to supply expensive and performant components. A complete set of protective systems is responsible for the reliability and non-failure operation of the power supply. The wires of t...his PSU model have a semi-modular principle of the device: the power wiring of the motherboard and the processor is non-removable, but all other wires can be used as needed. The active cooling system is represented by a 140 mm fan. The speed of rotation of the impeller depends on the load level. This PSU has an older modification, its rated power is 750 watts.

One of the most affordable PSUs with a Gold certification

For the money, Chieftec A-90 is one of the best options in the segment of high-quality PSUs with a capacity of 600 – 700 watts. When evaluating the block, first of all, it is worth noting the high efficiency in the region of 90% (there is a Gold certificate), and secondly, the use of modern circuitry and the element base. The latter provides a high load capacity of the +12V line and an acceptable state of all output voltages.

Silent operation

Also, it should be noted quite successful quiet and efficient cooling system. Plus, the platform on which this unit is based provides the presence of all types of protection and the use of a semi-modular cable design, which adds points to the model in terms of safety and functionality.

Perfect value for money

However, it was not without drawbacks. Compared to competitors with a gold certificate, the device from Chieftec operates in a relatively narrow range of input voltages (200 – 240 V), not all wires are unfastened from the case, and the cables are wrapped in cloth, and not combined into loops, which creates slight inconvenience during assembly. But given the price and all the positive factors, these little things can be easily closed eyes.
