The Cooler Master XG power supply series belongs to the premium segment and is designed for demanding gaming and work systems. These models have achieved a platinum efficiency certification, a fully modular cable system, reinforced primary +12V rail, and an extended 10-year warranty. Although the series was released in 2022 and complies with the ATX 2.5 standard instead of the newer ATX 3.0, in terms of reliability and component quality, it is absolutely top-tier.

The XG lineup is based on Cooler Master's proprietary platform with a modern full-bridge topology and LLC resonant converter in the primary circuit, synchronous rectifier, and DC-DC converters in the secondary. Active PFC and reliable Japanese Nippon Chemi-Con capacitors ensure stable operation and long lifespan, while the cooling system is tuned so that the 135 mm fan doesn't produce much noise even under serious load.

In fact, the series includes 2 XG modifications: the standard XG Platinum version with 650W power and the upgraded XG Platinum Plus model. The latter offers more power options (650, 750, and 850W), features built-in lighting (adjustable via Cooler Master MasterPlus+ utility), and has a side-mounted color four-digit indicator that alternately displays the fan speed, temperature of key components, and current power consumption. This set of features and capabilities makes the XG a great choice for those who are building a powerful system and want the power supply to be not just reliable, but also modern-looking.
