Chieftec CS-12B-300 PSU 300 W black

The narrow Desktop-style case with a width of just 102 mm is designed not for gaming builds, but for office and multimedia systems where compactness and inconspicuousness are more important than performance. It comes with a GPF-300P power supply unit with a power capacity of 300W and an 80 PLUS Bronze certification, eliminating the need to find a PSU separately and ensures basic energy efficiency.

The Chieftec CS-12B-300 case supports micro-ATX boards and can be installed both vertically and horizontally, which is convenient for placement under a monitor or in a narrow desk slot. The internal layout poses strict limitations: only low-profile video cards up to 195 mm in length are allowed, and the CPU cooler height is limited to 85 mm, narrowing choices to compact solutions with low thermal design power.

The presence of a 5.25" bay — a feature nearly vanished from modern cases but useful for installing an optical drive in workstations. Cooling is minimal, with only a single mount for an 80-mm fan at the front, and the fan is not included. The front panel is solid, without ventilation openings, and it features two USB 3.0 and two USB 2.0 ports. Weighing 4.2 kg with wall thickness of 0.6 mm are typical figures for the budget office segment.
