PSU Chieftec Navitas

Solid high-power branded power supply (1000 W), fully compliant with the ATX 12V 2.3 standard. It is one of the older models of the popular 2013 Chieftec Navitas line, which consists of 4 relatively affordable units with power from 750 to 1250 watts. It has a partially modular cable system. Positioned as a product of the middle price category, designed to power high-performance gaming systems with demanding video cards, including flagship video adapters in multiGPU configurations.

Suitable for powerful workstations, equipped with AMD Radeon Instinct and Nvidia Tesla professional computing accelerators. Cope with overclocking experiments, accompanied by an extreme increase in CPU and GPU Power Limit. It will be a reliable source of energy for multiGPU complexes involved in cryptocurrency settlements. The Chieftec Navitas GPM-1000C power supply is built on a reliable hardware platform with a resonant LLC converter and DC-DC converters. It shows high efficiency of the 80 Plus Gold level (90% efficiency), provides high voltage stability and can deliver all the nameplate power along the +12 V line. The block is 14 mm longer than the standard one.

Top without reservation

Chieftec does not quite add up with the Hi-End segment of power supplies. The company's range is full of serious models with power from 750 W, however, due to minor flaws and the need to save, few of them could impose serious competition on top models from Be quiet, Thermaltake and Seasonic. But the Navitas model has finally succeeded.

One of the most affordable options in the 1000W + 80+ Gold class

For $110, this model offers 1000W of power, which should be enough for any overclocker build, 90% efficiency (80+ Gold certified), a basic set of protections, 4 PCI-E slots and the ability to partially disconnect unnecessary cables to give the case decoration more tidy look. Considering the price, the Navitas' virtually only competitor in the 1000W + 80+ Gold class is the good but rather noisy Zalman EBT. Everything else will cost much more.

Runs a system with four GTX 1070 Ti

However, what is more important here is not the price, but the final result. Due to the use of advanced circuitry and high-quality element base, Chieftec Navitas in tests proved to be a trouble-free small, stably withstanding any load of any nature and duration. Most of all I liked the quiet ball-bearing cooler, the ability of the power supply unit to deliver power 15% higher than the nominal power (1150 W) for a short time, and the ability of the stabilization system to keep the supply voltage deviation range on the main lines within ± 2% (instead of the permissible ± 5%). You can only complain about only 4 PCI-E slots, which may not be enough to connect additional power to video cards. However, in fact, he calmly “started” a system with four GTX 1070 Ti with a little overclocking. And this is more a story about mining, not video games.
