Chieftec Core BBS-700S

Available gold

Chieftec Core is one of the most affordable PSU series with 80 PLUS Gold energy efficiency certification. Includes models from 500W to 700W, all with a non-modular design, which is in fact the only savings. Otherwise, these are quite modern PSUs based on the circuitry of CWT, a longtime partner of Chieftec (almost the only exception is Polaris on the High Power platform).

Separate stabilization

It is built on a progressive circuit of separate DC-to-DC stabilization of low-voltage lines +5 and +3.3 volts. However, it is not possible at all to achieve an efficiency of up to 92 percent when using old-school group stabilization (Bronze maximum).

Stable power supply

De jure, a wide input voltage range of 100 – 240 volts is designed for household electrical networks around the world. But de facto, it allows the Chieftec Core to work stably in east european country houses, where the voltage often sags much below normal — from 220 to 170 volts.

Long wires

The non-modular design made it possible to make the Chieftec Core extremely compact by the standards of ATX standard power supplies — only 14 cm in length. The cables, although not removable, are long: for example, the 4 + 4-pin processor power cable, which is traditionally the most problematic for hidden installation in a PC case, has a sufficient 65 cm.
