Chieftec is a brand that needs little introduction to experienced PC builders, particularly in the European market. Their reputation was built on rugged chassis designs like the Dragon series, and they have expanded to providing solid and reliable power supplies that you can install and forget about. In response to market competition, Chieftec partnered with Channel Well Technology (CWT)—one of the industry's most respected OEMs—to leverage their well tested and proven platforms for a series of models conforming to the latest specification and certification standards. CWT know that the root of reliability is often headroom, and compared to other similarly-sized 1200 W models, the layout is dense and parts are kept well away from component limits.

The Stealth SPX-1200-FC is a high capacity model designed to take whatever you can throw at it without any stress or fatigue. Fully compliant with the ATX 3.1 standard and featuring dual native 12V-2x6 PCIe 5.1 connectors, this 1200 W unit is built to accommodate the most power-hungry graphics cards on the market. The platform boasts an 80 Plus Platinum certification, an LLC Half-Bridge converter with DC-to-DC technology, and exclusively uses high-quality Japanese capacitors for maximum longevity.

The fan is a 135 mm FDB fan set up to run constantly or semi-passively, depending on if you favor regular airflow or complete silence when under light loads. The unit includes comprehensive protection features (OCP, OVP, SCP, OPP, UVP, OTP, SIP, AFC) and comes with a five-year warranty. Weighing 2.86 kg, it has dimensions of 140 × 150 × 86 mm.
